Description
Technical field
The invention belongs to a kind of oil field equipment, particularly a kind of large 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 the oil pipe tripping out more than large pump, 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 large pump is fixed on well head, oil pipe more than large pump is provided with and supports anchor fastening devices, so the oil pipe distance more than well head to the large pump supported between anchor is fixing, because the impact of oil pipe more than large pump by factors such as temperature risings can be extended, the situation of the oil pipe of more than large pump will be pressed, cause the tubing bending of more than large 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.
The object of the invention is to realize water blockoff assembly and flow string assembly is disposable goes into the well, simultaneously easy to connect, interchangeability good, and can realize the function of blowout prevention in oil pipe, water blockoff assembly anticreep and not pressuring oil pipe, save operating cost, shorten the activity duration.
Technical scheme provided by the invention is as follows: comprise from sealed packer, tapping pin, back-off packer, extension spring valve and packer setting switch, it is characterized in that: arrange from the vulcanizate tube inner surface of sealed packer the circular cone that angle is 12 degree; Be threaded from sealed packer lower end tapping pin upper end, and tapping pin is through back-off packer, extension spring valve and oil pipe and with one heart, the linkage section 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, reserved certain distance between the lower surface of built-in ball seat and the lower end female end of main body; 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 invention 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
The present invention forms by from sealed packer 1, tapping pin 2, back-off packer 3, extension spring valve 4, packer setting switch 5 five parts, wherein assemble from sealed packer 1 by existing product structure, the central tube 14 connecting top connection 11 is set, central tube 14 there is the bowl-shape sulfuration packing element 12 of two pieces by fixing sulfuration core 13 sulfuration, and each assembly such as the extension spring valve 4 of the built-in panel turnover switch F of tapping pin 2, back-off packer 3 and main body.
The drip irrigation device improved is as follows: arrange from sulfuration packing element 12 inner surface of sealed packer 1 circular cone that angle is a, angle a is 12 degree; Be threaded from sealed packer 1 lower end tapping pin 2 upper end, tapping pin 2 through back-off packer 3, extension spring valve 4 and oil pipe G and with one heart, the linkage section 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 G, and oil pipe G 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 of the present invention with the valve be connected under the large pump of the oil well pump in flow string from sealed packer 1 upper end, packer setting switch 5 lower end and water blockoff assembly are threaded connection, connect the degree of depth that rear G.I.H designs in advance, packer setting switch 5 plays the effect of blowout prevention, suppress in sleeve pipe E, bowl-shape sulfuration packing element 12 is made to be adjacent to sleeve pipe E inwall under the effect of the pressure, it is that the circular cone of a adds the contact area with sleeve pipe E inwall that sulfuration packing element 12 inner surface arranges angle, namely improve the active force of bowl-shape sulfuration packing element 12, strengthen the sealing function with sleeve pipe E simultaneously, fluid pressure enters in oil pipe G by the entrance pressure hole I on sealed packer 1, 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 J opens grappling, back-off packer 3 can be prevented, extension spring valve 4, packer setting switch 5 and water blockoff assembly are thrown off, operating personnel presses down the oil pipe of more than large pump, cut off the connection pin C of tapping pin 2 and back-off packer 3, on carry the oil pipe of more than large pump, this system is fixed on well head, when carrying out normal oil producing operation, disposable oil producing operation of going into the well can be realized.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, trip out the large pump of oil well pump, from sealed packer 1 and tapping pin 2, the panel turnover switch F of extension spring valve 4 closed, realizes blowout prevention in oil pipe.
The present invention is applicable to the large pump of oil well pump of oil recovery factory.
