Abstract
The utility model belongs to the technical field of underground operation in the field of petroleum and natural gas exploitation, in particular to a packer extruding and sealing device, which is characterized by at least comprising a ball seat, a compression type anchor packer, a bypass pipe and an oil pipe, wherein the ball seat, the compression type anchor packer, the bypass pipe and the oil pipe are sequentially connected through screw threads from bottom to top, and the oil pipe is connected to a well mouth; the compression type anchor packer is a Y221 packer. The packer extruding and sealing device lightens the labor intensity of workers and can finish extruding and sealing, pressure testing and lower oil layer protection through one trip.
Description
Technical field
The utility model belongs to the underground work technical field in natural petroleum gas field field, particularly a kind of extruding and sealing packer device.
Background technology
To the fuel-displaced and well of position, upper strata water outlet in lower floor position; if water exit is carried out squeeze seal; the blank tubing back-up sand is protected oil entry under then needing earlier; again water exit is carried out squeeze seal; to verify down after waiting with fixed attention that drilling tool carries out pressure testing checking or pumping checking; abrasive drilling is carried out if any screw drill under the cement plug elder generation in qualified back; descend blank tubing to carry out sand washing again; need multiple trips like this; a plurality of auxiliary links such as back-up sand are arranged before and after the squeeze seal, bore plug, sand washing etc.; long construction period, labor strength is big, the operating cost height.
Summary of the invention
The purpose of this utility model provides a kind of shortening construction period, alleviates labor strength and bores a process for extruding and sealing packer and the device that can finish squeeze seal, pressure testing, bottom oil layer protection.
The purpose of this utility model is to realize like this, a kind of extruding and sealing packer device, it is characterized in that: which comprises at least: ball seat, compression anchor packer, bypass pipe, oil pipe, from bottom to top by being threaded, oil pipe is connected to well head successively for ball seat, compression anchor packer, bypass pipe, oil pipe.
Described compression anchor packer is the Y221 packer.
The utility model has the advantages that:
Because process for extruding and sealing packer is that ball seat, compression anchor packer, bypass pipe are connected successively from bottom to top with oil pipe, pressurization sets the compression anchor packer and sits well head, and set good, pressurization makes and sets compression anchor packer packing element pressure-bearing and reach more than the 120KN, after finishing, the cement squeeze seal carries out big discharge capacity recoil with cementing truck immediately, unload well head, on carry several drilling tools, carry out big discharge capacity recoil once more, the purpose of recoil is that the cement paste in the compression anchor packer is rinsed well for the second time; Time coagulate qualified after, the position sets once more during down to former squeeze seal with drilling tool, carries out pressure testing and tests and levy.Solve like this and bore the technology requirement that just reaches squeeze seal, pressure testing checking and protect target zone simultaneously for one time, reduce job execution operations such as many times round trips, back-up sand, abrasive drilling, sand washing.Shorten construction period, reduce construction cost, alleviate labor strength.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the example structure schematic diagram.
Among the figure: 1, ball seat; 2, compression anchor packer; 3, bypass pipe; 4, oil pipe; 5, well head.
The specific embodiment
1) with ball seat 1, compression anchor packer 2, bypass pipe 3, oil pipe 4 successively from bottom to top by being threaded, connect oil pipe 4 to well head 5;
2) be drilled under on design attitude (oil layer section B) back and carry 1 meter-1.3 meters, rotation 1-3 circle, pressurization sets compression anchor packer 2 and sits well head, guarantee that compression anchor packer 2 sets below bypass pipe 3 perforated interval A about 1 meter, and setting well, pressurization makes and sets compression anchor packer 2 packing element pressure-bearings and reach more than the 120KN;
3) after cement squeeze seal construction finishes, carry out big discharge capacity recoil with cementing truck immediately, unload well head, on carry several drilling tools, carry out big discharge capacity recoil once more, the purpose of recoil is that the cement paste of 2 li of compression anchor packers is rinsed well for the second time;
4) wait to coagulate after 72 hours, the position during down to former squeeze seal with drilling tool is carried out pressure testing and is tested and levy.
The Y221 packer belongs to compression packer, adopts rotation to set.Before boring down, must fall groove to it to following brill state, under be drilled into design attitude after, on carry 1m-1.3m, dextrorotation 1-3 circle, the alignment pin in lower contact this moment skids off from the J type groove of traction body, the release central tube is descending, to at first close and seal bypass valve, and continue to transfer tubing string, it is descending to promote packing element and cone, because the rubbing action of the wiper block on the traction body, in transferring process, slips on the traction body and cone produce and relatively move, and cone will strut slips, make the slips on the packer firmly be anchored on the casing wall, continue to apply seating sealing load, the packing element of packer swells by compression, when load increases to 60-80KN, packer will reliably set, can reach the purpose that branch is asked packing this moment fully, but will realize packing under the condition of high voltage, load must be increased to more than the 120KN.After finishing construction, directly the upper lifting pipe post will at first be opened downforce on the bypass valve balance of packer, and continuing upper lifting pipe post packer will deblocking.Packer is in brill state down automatically behind the upper lifting pipe post, can continue this moment to pull out of hole, and also can directly transfer tubing string and continue to bore down, repeats to set action when need set and gets final product.This packer can need set repeatedly according to design.
