Abstract
The invention discloses a water cone controlled parallel canal type flow controller, which comprises a main fluid canal and a plurality of small throttling canals distributed on the external circumference of the main fluid canal in parallel, wherein the inner end of the small throttling canal is provided with threads for installing a throttling spray nozzle or a plug head; and both ends of the flow controller are provided with threads which are connected with the oil pipe of the water cone control tube pile of the horizontal well. With the flow controller, the distribution density of the flow controller can be greatly increased so that the flow borne by each flow controller keeps a lower value and the liquid supply of ground floor is uniform; the flow controller avoids forming of big saw type water cone and high-speed washout so as to change the hydraulic parameter of the flow controller quickly; moreover, the flow controller can greatly reduce the cost of the water cone control technology of the horizontal well.
Description
Technical field
The present invention relates to a kind of flow control valve, relate in particular to the parallel duct formula flow control valve of a kind of water awl control.
Background technology
At present, in oilfield exploitation procedure, the stratum feed flow flow control valve of horizontal well is that the mode that combines with sand control screen is used mostly, at the center of sand screen tubing string tubing string, in open hole well that does not need sand control and cased well, in the mode of nozzle control.The flow resistance of nozzle is little, and is very narrow to the control range of flow, bad adaptability.
And the horizontal section length of horizontal well does not wait from more than 100 meters to more than 1000 meters, normally about 500 meters, because the existence of pipe flow resistance, will make the skewness of net horizontal section stratum liquid supply rate, cause producing pressure differential there are differences, thereby water-coning phenomena occurs too early; Water awl is in case occur, and the moisture of oil well will fast rise, will have a strong impact on the production of oil well like this, influences the final economic benefit and the Oilfield developing benefit of individual well simultaneously.
Summary of the invention
The parallel duct formula flow control valve that the purpose of this invention is to provide the water awl control that a kind of control range to flow is wide, compliance is good.
The objective of the invention is to be achieved through the following technical solutions:
The parallel duct formula flow control valve of water awl of the present invention control comprises fluid main aperture road, the parallel one or more throttling pore road that is distributed with of the periphery in described fluid main aperture road, and the inner, described throttling pore road is equipped with throttle nozzle.
By the above-mentioned technical scheme that provides as can be seen, the parallel duct formula flow control valve of water awl of the present invention control, be distributed with one to a plurality of throttling pore road because main aperture road excircle is parallel, there is screw thread the inner in throttling pore road, be used to install throttle nozzle, the bore of the inner nozzle of installing in the aperture by the throttling pore road, quantity and aperture road or blind hole realize the control to flow resistance.By this parallel duct formula flow control valve, just can realize the accurate control on a large scale of fluid flow dynamic resistance, solve the technical bottleneck of horizontal well water awl control, the distribution density of flow control valve is increased greatly, the flow that each flow control valve is born keeps lower numerical value, prevent the high speed erosion and the hydraulic parameters of very fast change flow control valve, and can reduce the implementation cost of horizontal well water awl control technology aspect significantly.
Description of drawings
In order to be illustrated more clearly in the technical scheme of the embodiment of the invention, the accompanying drawing of required use is done to introduce simply in will describing embodiment below, apparently, accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite of not paying creative work, can also obtain other accompanying drawings according to these accompanying drawings.
