Abstract
The utility model provides a safety circulating valve, belongs to the technical field of testing-perforation combined operation and aims at solving the technical problem that a tested oil reservoir is complicated in geological structure and large in operation difficulty, well conditions are complicated and the like. The technical scheme for solving the technical field is that a circulating valve connector is radially provided with a circulating hole, and the upper end of the circulating valve connector is provided with oil pipe inner threads. A circulating upper mandrel is fixed through a shear pin and the circulating valve connector and connected with a circulating lower mandrel, a circulating valve connector and a connecting outer barrel through screw threads. The connecting outer barrel, the circulating upper mandrel, the circulating valve connector and a rupture disk are sealed through seal rubber rings. The upper portion of an escapement sleeve is a spring claw, and the lower portion of the escapement sleeve is in threaded connection with a connecting sleeve. A power arm is connected with the connecting sleeve in a hung mode. The safety circulating valve has the advantages that an oil-gas layer is sealed when testing is finished, upper and lower pressures of a packer are balanced, the stratum pumping action can be reduced in the trip-up process, and blowout accidents can be prevented.
Description
Technical field
The utility model belongs to the technical field of test-perforation integration of operation, and what be specifically related to is safe circulating valve.
Background technology
Along with the development of oil-gas exploration and deeply, formation testing layer geological structure becomes increasingly complex.Task difficulty is increasing, particularly in the formation testing test of deep-well, deep-well generally has the feature of high temperature, high pressure, not only will consider the safety of oil reservoir, oil well, down-hole string in the formation testing test to this well, also will consider problem and the corresponding measure that in work progress, may occur.
Summary of the invention
Become increasingly complex in order to overcome formation testing layer geological structure, task difficulty is increasing, particularly in the formation testing test of deep-well, the problems such as deep-well hole condition complexity, the utility model provides a kind of new type of safe circulating valve, mainly packing oil-gas Layer in the time that test finishes, downforce on balance packer, carries out cycle operation formation fluid is circulated, and discharges tubing string, in trip-out process, can reduce the swabbing action to stratum, prevent the generation of gas blowout accident.
Technical solution adopted in the utility model is: the utility model is grouped into by power section, valve body; Described power section is made up of circulating valve joint, circulation upper spindle, rupture disk, connection urceolus, circulation lower spindle; Circulating valve joint radially has circulation port, and upper end is shaped with oil pipe internal thread, can be connected with the oil pipe on top, and upper and lower two ends are sealed by O-ring seal; Circulation upper spindle is fixed by shear pin and circulating valve joint, and circulation upper spindle is with circulation lower spindle, circulating valve joint and be connected urceolus and all adopt screwed connection; Sealed by O-ring seal by connection urceolus, circulation upper spindle, circulating valve joint, rupture disk; Described valve body part is made up of ball valve urceolus, escapement cover, adapter sleeve, upper ball base body, power arm, spheroid, lower ball base body, lower contact, and spring detent is made on the top of escapement cover, and bottom and adapter sleeve are with screwed connection; Power arm is connected to hang with adapter sleeve, and the spherical plush copper on power arm coordinates with the hole on spheroid as operative pin.
The beneficial effects of the utility model are that this safe circulating valve is packing oil-gas Layer in the time that test finishes mainly, downforce on balance packer, carrying out cycle operation circulates formation fluid, discharge tubing string, in trip-out process, can reduce the swabbing action to stratum, prevent the generation of gas blowout accident.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1 circulating valve joint, 2 circulation upper spindles, 3 rupture disks, 4 connect urceolus, 5 circulation lower spindles, 6 ball valve urceolus, 7 escapement covers, 8 adapter sleeves, 9 upper ball base bodies, 10 power arms, 11 spheroids, 12 lower ball base bodies, 13 lower contacts, 14 circulation ports, 15 shear pins.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described: as shown in Figure 1, the utility model is grouped into by power section, valve body; Described power section is made up of circulating valve joint 1, circulation upper spindle 2, rupture disk 3, connection urceolus 4, circulation lower spindle 5.Circulating valve joint 1 radially has circulation port 14, and upper end is shaped with oil pipe internal thread, can be connected with the oil pipe on top, and when circulation upper spindle 2 is during in upper limit position, circulation port 14 is closed, and upper and lower two ends are sealed by O-ring seal; Circulation upper spindle 2 is fixing with circulating valve joint 1 by shear pin 15, and circulation upper spindle 2 is with circulation lower spindle 5, circulating valve joint 1 and be connected urceolus 4 and all adopt screwed connection.Sealed by O-ring seal by connection urceolus 4, circulation upper spindle 2, circulating valve joint 1, rupture disk 3, formed air chamber, the power that this part provides operation ball valve to close; After annular pressure breaks rupture disk 3, the annular pressure acting in differential area will be cut off shear pin 15, and circulation upper spindle 2 and circulation lower spindle 5 move downward, and have closed ball valve.Described valve body part is made up of ball valve urceolus 6, escapement cover 7, adapter sleeve 8, upper ball base body 9, power arm 10, spheroid 11, lower ball base body 12, lower contact 13, and spring detent is made on the top of escapement cover 7, and bottom and adapter sleeve 8 are with screwed connection.Power arm 10 is connected to hang with adapter sleeve 8, and can relative sliding, spherical plush copper on power arm 10 coordinates with the hole on spheroid 11 as operative pin, under annular pressure effect, circulation upper spindle 2 and circulation lower spindle 5 interlocks operation downwards, the spring detent on escapement cover 7 opens, and props up the inwall that connects urceolus 4, play the effect of direction-locking, make the closed safe, reliable of ball valve; Axle continues descending, drives power arm 10 to move by adapter sleeve 8, and power arm 10 promotes spheroid 11 by operative pin and makes it to turn to fastening position, exposes circulation port 14.
