Description
Technical field
The utility model belongs to a kind of oil field equipment, particularly a kind of screw pump oil pumping operating system.
Background technology
Before well recovery is produced, first water blockoff assembly to be gone into the well, after water blockoff assembly realizes water blockoff function, also need flowline, and again transfer flow string assembly, just can carry out oil producing operation, owing to repeatedly operating, make downhole technique more loaded down with trivial details, operating cost is higher, will trip out tubing string when workover treatment, but owing to not there is blowout prevention procedure, thus cause well head oil spout, waste energy and contaminated environment; Because oil pipe more than screw pump is fixed on well head, oil pipe more than screw pump is provided with and supports anchor fastening devices, so the oil pipe distance more than well head to the screw pump supported between anchor is fixing, because the impact of oil pipe more than screw pump by factors such as temperature risings can be extended, the situation of the oil pipe of pressing more than screw pump will be there is, cause the tubing bending of more than screw pump, produce serious eccentric wear, eccentric wear main harm is: cause oil pipe to miss; The iron filings holddown etc. that eccentric wear produces.The damage that eccentric wear makes oil pipe column too early, affects the normal production of oil well, needs well workover, add activity duration and operating cost greatly.
Summary of the invention
The purpose of this utility model is to realize water blockoff assembly and flow string assembly is disposable goes into the well, simultaneously easy to connect, interchangeability good, and the function of blowout prevention in oil pipe, water blockoff assembly anticreep and not pressuring oil pipe can be realized, save operating cost, shorten the activity duration.
The technical scheme that the utility model provides is as follows: comprise two-way anti-rotation anchor, tapping pin, back-off packer, extension spring valve and packer setting switch, it is characterized in that: the cylindrical of the main body of two-way anti-rotation anchor has many enclosed slots be distributed on circumferentially, in each enclosed slot, fixture block is installed, the card rib of fixture block is two dental structures, polylith be separated by the card of fixture block distracted be that clockwise direction is arranged, the be separated by card of fixture block of all the other polyliths is distracted for counterclockwise arranging; Arrange the leaf spring of support between fixture block and main body, leaf spring is tabular arcuate elastic elements, and the spacing ring that fixture block two ends are threaded connection in main body carries out spacing connection;
The lower end of two-way anti-rotation anchor is threaded tapping pin upper end, and tapping pin is through back-off packer, extension spring valve and oil pipe and with one heart, it is 30mm that the linkage section annular projection lower surface of tapping pin upper end and the central tube upper surface of back-off packer arrange preset space; The outer tube of tapping pin is connected by pin with the central tube of back-off packer, and back-off packer lower end is threaded connection the upper end of extension spring valve, and extension spring valve lower end is threaded connection oil pipe, and oil pipe lower end is threaded connection packer setting switch;
The built-in ball seat of main body of packer setting switch, and fixed by pin, between the lower surface of built-in ball seat and the lower end female end of main body, reserved certain distance is 12mm-20mm, and steel ball is arranged on ball seat port, and pressing plate is connected with main body screw steel ball is fixed.
Good effect of the present utility model is: achieve water blockoff assembly and flow string assembly is disposable goes into the well, easy to connect, interchangeability good, and there is the function of blowout prevention in oil pipe, water blockoff assembly anticreep and not pressuring oil pipe, not only save operating cost greatly, but also shorten the activity duration.

Detailed description of the invention
See Fig. 1-5, the utility model is made up of two-way anti-rotation anchor 1, tapping pin 2, back-off packer 3, extension spring valve 4, packer setting switch 5 five parts; Wherein by the extension spring valve 4 of the built-in panel turnover switch F of existing product structure assembling tapping pin 2, back-off packer 3 and main body.
The drip irrigation device improved is as follows: see Fig. 2-4, the cylindrical of the main body 11 of two-way anti-rotation anchor 1 has 6 enclosed slots be distributed on circumferentially, fixture block 14 is installed in each enclosed slot, the card rib of fixture block 14 is two dental structures (the amplification F portion see Fig. 4), the card of three pieces of fixture blocks 14.1,14.3,14.5 of being separated by is distracted is clockwise direction setting, and another three pieces of fixture blocks 14.2,14.4,14.6 of being separated by are for counterclockwise arranging; Arrange the leaf spring 13 of support between fixture block 14 and main body 11, leaf spring 13 is tabular arcuate elastic elements, and the spacing ring 12 that fixture block 14 two ends are threaded connection in main body carries out spacing connection;
The lower end of two-way anti-rotation anchor 1 is threaded tapping pin 2 upper end, tapping pin 2 through back-off packer 3, extension spring valve 4 and oil pipe J and with one heart, the linkage section annular projection lower surface of tapping pin 2 upper end and the central tube B upper surface of back-off packer 3 arrange preset space A, and preset space A is 30mm; The outer tube D of tapping pin 2 is connected by pin C with the central tube B of back-off packer 3, back-off packer 3 lower end is threaded connection the upper end of extension spring valve 4, extension spring valve 4 lower end is threaded connection oil pipe J, and oil pipe J lower end is threaded connection packer setting switch 5;
The built-in ball seat 5.5 of main body 5.1 of packer setting switch 5, and fixed by pin 5.4, reserved certain distance H between the lower surface of built-in ball seat 5.5 and the lower end female end of main body 5.1, distance H is 12mm-20mm, steel ball 5.3 is arranged on ball seat 5.5 port, and pressing plate 5.2 is threaded with main body 5.1 and steel ball 53 is fixed.
Operating principle
Be threaded connection by screw pump stator in upper end of the present utility model and flow string, lower end and water blockoff assembly are threaded connection, connected the degree of depth that rear G.I.H designs in advance, packer setting switch 5 plays the effect of blowout prevention, oil pipe is suppressed, cut off the pin 5.4 of packer setting switch 5, ball seat moves down certain distance H, switching channels is opened, oil well liquid is unidirectional upwards to flow, continue to suppress, back-off packer 3 is set, slips K opens grappling, back-off packer 3 can be prevented, extension spring valve 4, packer setting switch 5 and water clogging tool are thrown off, operating personnel presses down the oil pipe of more than screw pump, tapping pin 2 is cut off with the connection pin C of back-off packer 3, on carry the oil pipe of more than screw pump, this system is fixed on well head, when carrying out normal oil producing operation, thus realize disposable oil producing operation of going into the well.When screw pump oil pumping operation, the utility model, under the effect of screw pump rotor rotating torque, is anchored in sleeve pipe by fixture block 14.1,14.3,14.5 by fixture block 14, and the two dental structure F on fixture block better serve grappling effect, prevent screw pump stator from rotating.Owing to having cut off pin C, so distance A is variable, avoids oil pipe and extend due to factors such as intensifications the pressuring oil pipe situation produced, solve the problem of eccentric wear.When workover treatment, have torque reaction to produce during screw pump stopping, fixture block 14.2,14.4,14.6 serves reverse grappling effect, prevents screw pump stopping from having torque reaction to drive stator to rotate.Serve screw pump oil production system and overcome shutdown torque reaction, the effect of protection screw pump, trips out screw pump, two-way anti-rotation anchor 1 and tapping pin 2, the panel turnover switch I of extension spring valve 4 is closed, realizes blowout prevention in oil pipe.
The utility model is applicable to the oil producing operation of screw pump.
