Dispositivo desarenador de crudos Crude dewatering device
CAMPO DE LA INVENCIÓN FIELD OF THE INVENTION
La presente invención se relaciona con un sistema para la separación del petróleo del agua y sólidos de producción de densidad mayor al petróleo producido, tales como arena, arcillas, cuarzos, sales y otros tipos de mezclas de materiales líquidos con materiales sólidos. The present invention relates to a system for the separation of oil from water and production solids of greater density than the oil produced, such as sand, clays, quartz, salts and other types of mixtures of liquid materials with solid materials.
ANTECEDENTES BACKGROUND
En el proceso de la extracción de petróleo del subsuelo siempre existe el problema de la presencia de sólidos y agua de producción en la corriente del mismo, particularmente cuando se esta llegando al límite de la vida útil del pozo. La arena y el agua se separan del petróleo de manera natural por efecto de la gravedad, donde la arena y el agua se decantan y se pueden retirar del fondo de cualquier depósito. In the process of extracting oil from the subsoil there is always the problem of the presence of solids and production water in the same stream, particularly when it is reaching the limit of the useful life of the well. Sand and water are separated from oil naturally by gravity, where sand and water are decanted and can be removed from the bottom of any deposit.
Este proceso de separación natural es muy lento cuando se trata de separar grandes volúmenes de petróleo contaminado con arena y agua, a menos que se empleen grandes tanques o pozos de sedimentación. El costo de construir y mantener tales estructuras hace que esta opción sea muy poco práctica, particularmente en los campos de exploración donde el espacio disponible es limitado. This natural separation process is very slow when it comes to separating large volumes of oil contaminated with sand and water, unless large tanks or sedimentation wells are used. The cost of building and maintaining such structures makes this option very impractical, particularly in exploration fields where available space is limited.
En procura de encontrar otras alternativas, se han desarrollado múltiples sistemas para limpiar el petróleo y remover el agua, la arena y otros sólidos suspendidos en él, permitiendo así obtener un petróleo crudo relativamente limpio, que no va a generar efectos indeseables en los oleoductos y en otros sistemas de transporte y almacenamiento que entran en contacto con el petróleo. La mayoría de los sistemas de separación buscan mejorar la tasa a la cual se separa la arena y el agua del petróleo, pero estos requieren de grandes superficies y no son fáciles de construir en zonas cercanas a los pozos de extracción. In search of finding other alternatives, multiple systems have been developed to clean the oil and remove the water, sand and other solids suspended in it, thus allowing to obtain a relatively clean crude oil, which will not generate undesirable effects on the pipelines and in other transport and storage systems that come into contact with oil. Most separation systems seek to improve the rate at which sand and water are separated from oil, but these require large areas and are not easy to build in areas near the extraction wells.
Con el fin de reducir la necesidad del uso de grandes superficies o tanques de sedimentación de gran capacidad, los inventores de la presente invención han desarrollado un sistema innovador para mejorar la velocidad y tasa de separación del agua y los sólidos del petróleo, en este proceso no solo se usa la separación gravitacional sino las fuerzas de inercia, los diferenciales de cantidad de movimiento y las fuerzas de arrastre que ejercen los líquidos a los sólidos en el suspendidos. Esto es que también se usa energía del movimiento del agua presente en la corriente de petróleo proveniente del pozo de extracción para acelerar la separación de la arena y el petróleo. In order to reduce the need for the use of large surfaces or large capacity sedimentation tanks, the inventors of the present invention have developed an innovative system to improve the speed and rate of separation of water and petroleum solids, in this process not only gravitational separation is used but the forces of inertia, the differentials of amount of movement and the drag forces exerted by liquids on solids in the suspended. This is that energy from the movement of water present in the oil stream from the extraction well to accelerate the separation of sand and oil.
La presente invención se basa en la dinámica de los materiales con diferentes gravedades específicas con el fin de promover la separación de la arena y otros sólidos suspendidos de una corriente de petróleo. El principio consiste básicamente en hacer fluir la corriente de los fluidos de producción recién extraída del pozo por un espacio en donde se potencian las diferencias de fuerzas de inercia, cantidad de movimiento y arrastre con el fin de propiciar el contacto entre el agua presente en la corriente y los sólidos suspendidos, logrando así una separación de los sólidos y propiciando su separación por efecto de la gravedad. Este sistema tiene como una de sus características principales que la separación es dinámica y estable o sea que no hay acumulación de materiales en el sistema de tratamiento. The present invention is based on the dynamics of materials with different specific gravities in order to promote the separation of sand and other suspended solids from an oil stream. The principle basically consists in making the flow of production fluids fresh from the well flow through a space where differences in inertia forces, amount of movement and drag are enhanced in order to promote contact between the water present in the current and suspended solids, thus achieving a separation of solids and promoting their separation due to gravity. This system has as one of its main characteristics that the separation is dynamic and stable, that is, there is no accumulation of materials in the treatment system.
La solicitud de patente WO 2004/004863 enseña un proceso para la separación de arena del petróleo en el cual se emplea un tanque pequeño en el cual se fomenta la separación de la arena mediante el uso de irradiación ultrasónica para llevar a cabo la separación en un tanque horizontal relativamente pequeño. Dicho proceso es tecnológicamente complejo y costoso de mantener, por lo que es necesario encontrar una solución diferente de menor costo. Patent application WO 2004/004863 teaches a process for the separation of sand from oil in which a small tank is used in which the separation of the sand is encouraged by the use of ultrasonic irradiation to carry out the separation in a relatively small horizontal tank. This process is technologically complex and expensive to maintain, so it is necessary to find a different solution at a lower cost.
Por otro lado, la solicitud de patente US 5.770.078 describe un aparato para separar mezclas de líquidos y partículas finas suspendidas en estos. El aparato del arte previo consiste de un tanque vertical en la parte lata del cual se coloca una lámina perforada, debajo de la cual se desprenden una serie de mamparas que forman una retícula. El líquido con las partículas suspendidas ingresa por la parte baja del tanque y asciende, pasando por la retícula de mamparas y por la lámina perforada, saliendo por la parte superior del tanque con un contenido menor de partículas suspendidas. Si bien dicho sistema es eficiente para remover partículas suspendidas en fluidos poco viscosos, presenta problemas de obstrucción cuando se emplean fluidos como el petróleo crudo mezclado con arena. Además, el dispositivo del arte previo no permite retirar de manera simultánea parte del agua comprendida en la corriente de petróleo crudo. On the other hand, patent application US 5,770,078 describes an apparatus for separating mixtures of liquids and fine particles suspended therein. The prior art apparatus consists of a vertical tank in the can portion of which a perforated sheet is placed, under which a series of screens that form a grid are detached. The liquid with the suspended particles enters the lower part of the tank and ascends, passing through the screen grid and through the perforated sheet, leaving the upper part of the tank with a smaller content of suspended particles. Although this system is efficient for removing suspended particles in low-viscosity fluids, it presents obstruction problems when fluids such as crude oil mixed with sand are used. In addition, the prior art device does not allow simultaneous removal of part of the water included in the crude oil stream.
Por lo tanto, existe la necesidad de un sistema que permita trabajar con fluidos altamente viscosos y que además posibilite la remoción no solo de los sólidos suspendidos sino también del agua presente en corrientes de petróleo crudo. RESUMEN Therefore, there is a need for a system that allows working with highly viscous fluids and that also allows the removal not only of suspended solids but also of water present in crude oil streams.

Figure 5 shows a cross-sectional view of the intake and separation system of the present invention, in which the junction points of the main duct (4) to the upper ducts (5) and the lower ducts (6) can be seen ). The points of attachment to the upper ducts (9) have a diameter between 1/5 and 1/3 of the diameter of the main duct, while the points of attachment to the lower ducts (10) have a diameter between 1 and 1.5 times the diameter of the points of attachment to the upper ducts (9).
El tanque de separación (1) tiene una altura entre 2 y 5 veces su diámetro y la parte inferior del mismo tiene una forma cónica con una altura equivalente a entre 1/3 y 1/10 de la altura total del tanque. En la base del tanque se encuentra una válvula de salida (11) que regula la remoción de los sólidos depositados en el fondo del tanque. Adicionalmente, la parte superior del tanque comprende una válvula de salida (12) que regula el flujo de líquido libre de sólidos suspendidos que asciende a la parte alta del tanque (1). The separation tank (1) has a height between 2 and 5 times its diameter and the lower part thereof has a conical shape with a height equivalent to between 1/3 and 1/10 of the total height of the tank. At the base of the tank is an outlet valve (11) that regulates the removal of solids deposited at the bottom of the tank. Additionally, the upper part of the tank comprises an outlet valve (12) that regulates the flow of liquid free of suspended solids that ascends to the upper part of the tank (1).
Sin querer ceñirse a una teoría específica, el solicitante propone el siguiente principio de operación para el sistema de su invención. El petróleo proveniente del pozo entra al tanque por el ducto de alimentación a una velocidad tal que garantiza un flujo adecuado para la separación. A esta velocidad y en el espacio reducido del ducto principal (4), las moléculas de agua libre presentes en la corriente de petróleo comienzan a colisionar con las partículas de sólidos suspendidos en dicha corriente fomentando la separación y el arrastre de los mismos. De igual manera, debido al flujo las partículas de sólidos suspendidos de mayor tamaño se decantan y arrastran las partículas más pequeñas. Por los orificios en la parte inferior del ducto principal (10) sale una corriente rica en sólidos suspendidos y agua capturada por dichos sólidos, en tanto que por los orificios de la parte superior (9) sale una corriente rica en petróleo. El contenido de sólidos suspendido disminuye a lo largo del ducto principal, de tal manera que al final de dicho ducto la presencia de sólidos en la corriente es mínima. Without wishing to adhere to a specific theory, the applicant proposes the following principle of operation for the system of his invention. Oil from the well enters the tank through the feed pipeline at a speed that ensures adequate flow for separation. At this speed and in the reduced space of the main duct (4), the free water molecules present in the oil stream begin to collide with the particles of solids suspended in said stream, promoting their separation and entrainment. Likewise, due to the flow the particles of suspended solids of greater size decant and drag the smaller particles. A stream rich in suspended solids and water captured by said solids flows out of the holes in the lower part of the main duct (10), while an oil-rich stream flows out of the holes in the upper part (9). The suspended solids content decreases along the main duct, so that at the end of the duct the presence of solids in the stream is minimal.
Este proceso se repite nuevamente en los ductos inferiores (6) y superiores (5) unidos al ducto principal. En los ductos inferiores (6) los sólidos suspendidos fomentan aún más la separación de sólidos y agua de la corriente de petróleo, en tanto que en los ductos superiores (5) el petróleo al ser forzado por un área aún menor promueve la unión de las gotas de agua dispersas y los sólidos suspendidos restantes, logrando su separación. Por lo tanto, el dispositivo de la presente invención no solo remueve sólidos suspendidos en corrientes líquidas, sino también mejora la remoción de agua de corrientes de petróleo crudo recién extraído del pozo a un costo menor y en un área superficial mucho más pequeña que los sistemas empleados convencionalmente en el estado del arte. This process is repeated again in the lower (6) and upper (5) ducts connected to the main duct. In the lower pipelines (6) the suspended solids further promote the separation of solids and water from the oil stream, while in the upper pipelines (5) the oil being forced by an even smaller area promotes the union of the dispersed water drops and the remaining suspended solids, achieving their separation. Therefore, the device of the present invention not only removes suspended solids in liquid streams, but also improves the removal of water from crude oil streams just extracted from the well at a lower cost and in a much smaller surface area than the systems conventionally used in the state of the art.
