Abstract

The utility model relates to an unpowered piston type capsule oil increasing device in the field of oilfield oil production. The technical program is that the oil increasing device includes an oil pumping machine beam, a connecting bar and a pump barrel, which is characterized in that the oil pumping machine beam is hinged with the connecting bar through an upper hinged support, the other end of the connecting bar is connected to a piston provided in the pump barrel, three sealed rings are provided between the piston and the pump barrel, an oil storage chamber is penetrated in the lower part of the pump barrel, oil capsules are provided in the oil storage chamber, the oil capsules in the oil storage chamber are connected to the discharge pipelines through an inlet uniflow valve and an outlet uniflow valve, a safety valve is arranged on the bottom of the oil storage chamber, the safety valve is connected to the oil well port through a gate valve, and the lower part of the oil storage chamber is connected to a lower hinged support through a cardan joint. The utility model has effects of avoiding the crude petroleum from directly entering inside the pump body, scratching the soft sealed rings and plungers, resulting in the occurrence of oil spills, at the same time achieve the effect of oil pumping and oil increasing.

Description

A kind of unpowered piston type capsule increases oily device

Technical field

A kind of unpowered piston type capsule that the utility model relates in the oil recovery field, oil field increases oily device.

Background technology

The utility model is the improvement of being done on the basis of the utility model patent of application on November 14th, 2006 the patentee, patent name is " the unpowered oil rig of a kind of plunger type ", the patent No. 200620009571.2, its technical scheme is: comprise the connecting rod with oil pumper walking beam hinge, the other end of connecting rod and pump housing plunger hinge, five sealing rings are arranged between plunger and the pump barrel, the sealing ring J type of the top, middle three sealing rings are the height lip, the sealing ring of below is an O shape, the bottom of pump barrel is equipped with safety valve, the bottom of pump barrel is provided with import ball-and-seat and outlet ball-and-seat, be connected gate valve and well head gate valve successively between import ball-and-seat and the well head, between gate valve and well head gate valve, be connected with ball valve and pressure meter by tee piece, be connected ball valve by tee piece between well head gate valve and the oily main line gate valve, Parallet three-way valve pipe and gate valve between outlet ball-and-seat and the oily main line, tee piece connects ball valve and pressure meter, the advantage of technique scheme is that it need not to increase power, twitch up and down by the oil pumper walking beam, realized not changing the original production parameter, reduce wellhead back pressure, the oil well casing pressure, improve the polished rod system effectiveness, increase the oil well crude output, reach energy-saving and cost-reducing effect, but also have following shortcoming simultaneously: crude oil directly enters in the plunger displacement pump during oil pumping, crude oil includes sand and scratches plunger soft seal circle and plunger, cause leakage of oil, and the internal construction complexity, trouble made.

Summary of the invention

The purpose of this utility model is exactly at existing situation, provides a kind of and avoids crude oil to enter in the pump housing and a kind of unpowered piston type capsule simple in structure increases oily device.

Its technical scheme is: comprise oil pumper walking beam, connecting rod and pump barrel, described oil pumper walking beam is hinged by last free bearing and connecting rod, the other end of the connecting rod piston interior with being arranged on pump barrel is connected, be provided with three sealing rings between piston and the pump barrel, the bottom of pump barrel connects accumulator is set, be provided with oil capsule in the accumulator, be connected petroleum pipeline by the import ball-and-seat with the outlet ball-and-seat by the oil capsule in the accumulator, the bottom of accumulator is provided with safety valve, safety valve is connected with the oil well mouth by gate valve, and the bottom of accumulator connects free bearing down by universal joint.

Effect of the present utility model is: avoided crude oil directly to enter pump housing inside, scratched soft seal circle and plunger, caused the generation of oil accident, realized that oil pumping increases the effect of oil simultaneously again, and simple in structure, cost of manufacture reduces.

Description of drawings

Accompanying drawing is the structural representation of present embodiment, and 1 is the oil pumper walking beam among the figure, the 2nd, and connecting rod, the 3rd, piston, the 4th, petroleum pipeline, the 5th, outlet ball-and-seat, the 6, the 15th, pressure meter, the 7th, ball valve, 8, the 16th, gate valve, the 9th, oily main line, the 10th, oily main line gate valve, the 11st, well head, the 12nd, well head gate valve, the 13, the 14th, ball valve, the 17th, import ball-and-seat, the 18th, safety valve, the 19th, accumulator, the 20th, oil capsule, the 21st, pump barrel, the 22nd, universal joint, the 23rd, confinement plate, the 24th, last free bearing, the 25th, following free bearing, the 26th, sealing ring;

The specific embodiment:

With reference to accompanying drawing, present embodiment comprises oil pumper walking beam 1, connecting rod 2 and pump barrel 21, described oil pumper walking beam 1 is hinged by last free bearing 24 and connecting rod 2, the other end of connecting rod 2 is connected with piston 3 in being arranged on pump barrel 21, be provided with three sealing rings 26 between piston 3 and the pump barrel 21, the bottom of pump barrel 21 connects accumulator 19 is set, be provided with oil capsule 20 in the accumulator 19, be connected petroleum pipeline 4 by import ball-and-seat 17 with outlet ball-and-seat 5 by the oil capsule 20 in the accumulator 19, the bottom of accumulator 19 is provided with safety valve 18, safety valve 18 is connected with oil well mouth 11 by gate valve 12, and the bottom of accumulator 19 connects free bearing 25 down by universal joint 22.

Also can be: on pump barrel 21, aircleaner is installed, exhaust opening and fluid injection pressure hydraulic fluid port are installed on accumulator 19, confinement plate 23 is set in the accumulator 19, prevent the through hole that oil capsule 20 stops up between pump barrels 21 and the accumulator 19 with above-mentioned technological improvement.

Its workflow:

Close oily main line gate valve 10 before the start,

open gate valve

12,16,8,14 and 7, observe

pressure meter

6 and 15, close Sampling ball valve 13, starting up's pump work is when oil pumper is up, oil pumper walking beam 1 drives piston 3 and rises, crude oil in the well head 11 is inhaled in the oil capsule 20, and at this moment, well head 11 back pressure are very little, when oil pumper is descending, crude oil in the oil capsule 20 enters in the oily main line 9 by outlet ball-and-seat 5 and gate valve 8, and is moving and so forth.

This device is suitable for stratum fluid production force abundance, does not have the rod-pumped well of transferring the ginseng ability, is suitable for the rod-pumped well that pump leakage, oil pipe leakage etc. cause that pump efficiency reduces; It is higher also to be suitable for the oil well dry-pressing, influences the oil pumper of crude output, is applicable to that conventional all kinds beam pumping unit well installs and uses.
