Description
Technical field
The utility model relates to the field, oil field, specifically water injection well location pressure measurement disconnecting apparatus.
Background technology
During present water injection well in oil fields static pressure test, need to use the equipment such as lubricator, pulley, cylinder, make that the well head facility is many, the well testing truck carrying is overweight, the well head facilities such as lubricator that are contained in simultaneously on the well head also may be lost, the phenomenons such as blowout-preventing choke plug seepage perhaps occur, be unfavorable for the admission of environmental protection and data.
Summary of the invention
The facility that need to use when overcoming existing water injection well pressure measurement is many, make the well testing truck carrying heavy, and be prone to the deficiency of Seepage, the utility model provides a kind of water injection well location pressure measurement disconnecting apparatus, the application of this water injection well location pressure measurement disconnecting apparatus does not need to carry too much well head facility when making pressure measurement, alleviated well testing load capacity, reduce cost, can avoid the well head seepage simultaneously.
The technical solution of the utility model is: a kind of water injection well location pressure measurement disconnecting apparatus, comprise the locator main body, locator main body upper end is connected with fishing bell, described locator main body upper cavity is built-in with spring A, locator main body middle part axially has several grooves, be provided with the location centralizing arm in the groove, described location centralizing arm top is fixed on the locator main body by shipping and reselling on another market, the locator main body of location centralizing arm bottom is built-in with movably cylinder, cylinder is built-in with spring B, and the spring B upper end is fixed by bearing pin, and described bearing pin two ends are fixed on the locator main body; Described locator lower body part has groove along axis, is connected with lockwheel by rotating shaft in the groove, and an end of lockwheel contacts with bottom of cylinder, and off-centre is connected with claw on the lockwheel.
Have axial strip groove on the described cylinder side wall, two ends were fixed on the locator main body after bearing pin passed groove.
The utlity model has following beneficial effect: owing to take such scheme, be inlaid with lockwheel and claw in the housing, claw rotates and can drive the lockwheel rotation, make cylinder break away from stopping of lockwheel, be subjected to the elastic force of spring and move down, thereby unclamp the location centralizing arm, the location centralizing arm is ejected, prevent that instrument from falling well, thereby can remove well head and the ground installation such as lubricator during pressure measurement, realize single cylinder multiwell test, saved lubricator, the well head pulley, the ground installations such as cylinder reduce the phenomenon that seepage occurs, have reduced on the one hand cost, simultaneously also alleviate operating personnel's labour intensity, alleviated the load of vehicle.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1-fishing bell among the figure, 2-locator main body, 3-spring A, the 4-spring base, 5-ships and resell on another market, 6-location centralizing arm, 7-groove, 8-cylinder, 9-bearing pin, 10-spring B, 11-claw, 12-lockwheel, 13-pressure gauge cylinder.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, a kind of water injection well location pressure measurement disconnecting apparatus comprises locator main body 2, and locator main body 2 upper ends are connected with fishing bell 1, are connected with fishing head by fishing bell 1.Described locator main body 2 upper cavity are built-in with spring A3, spring A3 bottom is fixing by spring base 4, and locator main body 2 middle parts axially have several grooves, and groove is along circumferentially uniform, can according to the diameter quantification of locator main body 2, be generally 2.Be provided with location centralizing arm 6 in the groove, described location centralizing arm 6 tops 5 are fixed on the locator main body 2 by shipping and reselling on another market, and the top of location centralizing arm 6 contacts with spring base 4, and spring base 4 is descending to be promoted location centralizing arms 6 and 5 rotate along shipping and reselling on another market, thereby stretches out locator main body 2 outsides.The locator main body 2 of location centralizing arm 6 bottoms is built-in with cylinder 8, is matched in clearance between cylinder 8 and the locator main body 2, and cylinder 8 can move up and down.Cylinder 8 is built-in with spring B 10, and spring B 10 upper ends are fixing by bearing pin 9, and spring B 10 lower ends withstand on cylinder 8 bottom surfaces.Have two relative axial strip grooves on described cylinder 8 sidewalls, two ends were fixed on the locator main body 2 after bearing pin 9 passed groove.Described locator main body 2 bottoms have groove along axis, are connected with lockwheel 12 by rotating shaft in the groove, and an end of lockwheel 12 contacts with cylinder 8 bottoms, and off-centre is connected with claw 11 on the lockwheel 12, and claw 11 rotates and can drive lockwheel 12 rotations.The locator bottom part body is connected with pressure gauge cylinder 13.
The course of work of this disconnecting apparatus is such: will take off the cassette fishing head and be connected with the fishing bell 1 of this disconnecting apparatus, and disconnecting apparatus is lowered into injection well downhole flow regulator or horn mouth bottom after connecting manometer, at this moment, claw 11 upwards rotates, income is in the groove at locator main body 2 middle parts, simultaneously, location centralizing arm 6 also is recovered in the locator main body 2, and the boss of its lower end is stuck on the cylinder 8.Then carry instrument on, claw 11 is subject to the backward lower rotation of friction of tube wall, driving simultaneously lockwheel 12 rotates, unclamp cylinder 8 is supported, cylinder 8 moves down under the elastic force effect of spring B 10, unclamp the stopping of location centralizing arm 6 lower end boss, and location centralizing arm 6 outwards opens under the elastic force effect of upper end spring A3; Transfer instrument to the box cupling place that injection well downhole flow regulator or oil pipe are connected with oil pipe, location centralizing arm 6 is stuck in the box cupling place, prevents that the pressure measurement instrument from falling well again, and this moment, fishing head discharged this disconnecting apparatus, carried out pressure measurement, tripped out simultaneously and took off the cassette fishing head, disassembled blooie pipe.After the pressure measurement time finishes, be lowered to fishing head and salvage instrument, pressure measurement is finished.
Owing to adopt this disconnecting apparatus, blooie pipe can be dismantled, realized " well one pipe one pulley ", reached simple in structure, cost is low, alleviated labour intensity, realizes the possibility of single cylinder multiwell test, has shortened labour hour.
