Abstract
The utility model relates to a rubber stopper packer which comprises a pipe mandrel, at least two of bowl-sealed rubber stoppers which are sequentially connected with each other, and a press ring, wherein the bowl-sealed rubber stoppers are sheathed at the outer side of the pipe mandrel, and the press ring is tightly pressed to locate the bowl-sealed rubber stoppers and be fixed with the pipe mandrel in a sealing way; and the outer diameter of each bowl-sealed rubber stopper is larger than the diameter of an open hole. The rubber stopper packer with the structure can provide a preferable technical solution for completing a soil locating horizontal well, sectionally grouting during normally pipelaying, etc. According to the size of the diameter of the open hole, the bowl-sealed rubber stoppers with different diameters can be designed to meet the requirement for packing the horizontal wells with different hole diameters.
Description
Technical field
The utility model relates to a kind of packing instrument that a kind of annular gap that is used for interior pipeline of directed horizontal well and bore hole carries out packing, the purpose that pipeline and bore hole annular gap are carried out packing is in order to carry out segmentation well cementation or other special operation, and particularly a kind of soil environment is administered the packer of directed horizontal well completion operation.
Background technology
At present, external a lot of soil environments are administered and are all adopted peupendicular hole soil to be carried out modes such as exhaust or gas injection, carry out soil environment and administer, and domestic soil environment is administered at the early-stage.Yet, administer the directed horizontal wells that adopt for the large area region soil environment more, adopt horizontal well to mainly contain following advantage: to adopt horizontal well for the pollution in wide area zone, can reduce integrated cost; Adopt horizontal well to help controlling the further diffusion of pollution more; Have on the face of land under the situation in obstruction (for example building, river), can only adopt horizontal well to carry out soil environment and administer.When soil environment administer to adopt directed level, when implementing completion practice, need carry out different operations, thereby need the annular gap between packing horizontal well gut line and bore hole different pipe sections.How needing to adopt the packer of different packing modes according to different bottoms is technical barriers that those skilled in the art need to be resolved hurrily.
The utility model content
In view of this, the purpose of this utility model be to provide a kind of can the directed horizontal well gut line of packing and the packer of bore hole annular gap, satisfy the completion practice requirement of directed horizontal well.
For achieving the above object, the technical scheme that the utility model adopted is: a kind of plug packer, the bowl sealing plug and the pressure ring that comprise the die axle, connect more than two successively, this bowl sealing plug sleeve is located at the outside of die axle, this pressure ring compress location this bowl sealing plug and with die axle sealing and fixing mutually; The external diameter of described bowl sealing plug is greater than the diameter of bore hole.
The drift angle of described bowl sealing plug is 45 °.
External diameter 〉=1.2 times bore hole the diameter of described bowl sealing plug.
Described bowl sealing plug is a bowl-type.
Described bowl sealing plug is provided with two side by side.
Technique effect of the present utility model is as follows: plug packer of the present utility model, can be the completion of the directed horizontal well of soil and the operation of conventional pipe laying segmenting slip casting etc., and preferable technical solution is provided.According to the size of naked bore dia, the bowl sealing plug of design various outer diameter can satisfy the packing requirement of different apertures horizontal well.
Description of drawings
Fig. 1 is the packing sectional view of the utility model plug packer.
The specific embodiment
Be described below in conjunction with the specific embodiment of accompanying drawing the utility model plug packer.
As shown in Figure 1, plug packer of the present utility model, it includes die axle 1, bowl sealing plug 2 and pressure ring 3.Its structure comprises: a bowl sealing plug sleeve is located at the die axle outside, this pressure ring 3 compress location this bowl sealing plug 2 and with die axle 1 sealing and fixing mutually; The two ends correspondence of bowl sealing plug respectively adds a pressure ring 3, from axially applying suitable pressure, carries out wiper seal and fixes.In the present embodiment, bowl sealing plug 2 is provided with two side by side, and bowl sealing plug 2 is a bowl-type, and drift angle is 45 °, and external diameter 〉=1.2 times bore hole diameter contacts closely with hole wall.The dish plug adopts certain compression performance (＜30%) and the good rubber parts of elasticity,
When being lowered to horizontal well, the horn mouth of plug packer is outside, helps into well, finishes the packing to pipeline and bore hole annular gap when going into automatically, thereby can carry out other operation.
Adopt the plug packer of the utility model structure, can be the completion of the directed horizontal well of soil and conventional pipe laying slip casting operation etc., preferable technical solution is provided.According to the size of naked bore dia, design various outer diameter bowl sealing plug can satisfy the packing requirement of different apertures horizontal well.
The above is a preferred embodiment of the present utility model only, is not to be used for limiting to claim of the present utility model, and the equivalent structure that all utilization the utility model manuals and accompanying drawing content are done changes, and all in like manner is contained in the scope of the present utility model.
