According to the oil-pumping operation system of the small-diameter pump, a water plugging assembly and a tubular column production assembly can go down to a well at the same time; the oil-pumping operation system is convenient in connection and good in interchangeability, has the functions of blowout preventing in oil pipe, water plugging assembly dropping preventing and oil pipe pressing preventing, and is saved in operation cost and shortened in operation time.
Description
Technical field
The invention belongs to a kind of oil field equipment, particularly a kind of little 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 little pump is fixed on well head; oil pipe more than little pump is provided with and supports anchor fastening devices; so the oil pipe distance more than well head to the little pump supported between anchor is fixing; because the impact of oil pipe more than little pump by factors such as temperature risings can be extended; will press the situation of the oil pipe of more than little pump; cause the tubing bending of more than little 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 suspension standing valve, tapping pin, back-off packer, extension spring valve and packer setting switch, it is characterized in that: suspension standing valve lower end is threaded tapping pin upper end, tapping pin is through back-off packer, extension spring valve and oil pipe and with one heart, 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 connects by being connected 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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 sets switch structure diagram.
Detailed description of the invention
See Fig. 1,2, the present invention is made up of suspension standing valve 1, tapping pin 2, back-off packer 3, extension spring valve 4, packer setting switch 5 five parts; Wherein be built-in with the suspension standing valve 1 of steel ball by existing product structure assembling, the main body of suspension standing valve 1 and the lower contact I of suspension standing valve are threaded connection; 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 all adopts existing product structure.
The drip irrigation device improved is as follows: suspension standing valve 1 lower end is threaded 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 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 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 5. 3 is fixed.
Operating principle
The little pump of oil well pump in suspension standing valve 1 upper end of the present invention and flow string is threaded connection, 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, oil pipe is suppressed, cut off the pin 5.4 of packer setting switch 5, ball seat moves down certain distance H, oil well liquid is unidirectional upwards to flow, continue to suppress, back-off packer 3 is set, slips E 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 little pump, cut off the connection pin C of tapping pin 2 and back-off packer 3, operating personnel carries the oil pipe of more than little pump, this system is fixed on well head, when carrying out normal oil producing operation, the plunger of the little pump of the oil well pump in flow string promotes the resilient sleeve of suspension standing valve 1, resilient sleeve moves down along lower contact male cone (strobilus masculinus), steel ball in resilient sleeve falls within lower contact I, play the effect of upwards liquid one-way flowing, thus realize disposable oil producing operation of going into the well.Owing to having cut off connection pin C, so distance A is variable, when oil pipe extends due to factors such as temperature the situation that just there is not pressuring oil pipe, solve the problem of eccentric wear.When workover treatment, trip out the little pump of oil well pump, suspension standing valve 1 and tapping pin 2, the panel turnover switch F of extension spring valve 4 is closed, realizes blowout prevention in oil pipe.
The present invention is applicable to the little pump of oil well pump of oil recovery factory.
