Abstract
The utility model relates to a long-distance hydraulic oil pump composed of an oil reciprocating pump mounted at the bottom of the shaft oil pipe, belonging to pump technical field. The bottom port of the oil pipe is screwed on an upper pump cover of the oil pump; an upper short connector, a pump cylinder, a lower short connector, a lower pump cover, a pump head and a choke are screwed at the bottom of the upper pump cover in turn; oil incoming path of the choke gets through a check valve, a side hole of the check valve on the lower pump cover and an annular gap in the pump case bushing and communicates upwards with the hole path of the upper pump cover for entering the oil pipe. The upper and lower ports of the pump case bushing are nested with the upper and lower pump covers respectively; and the outlet connecting pipes of the positive and negative frequency hydraulic pumps mounted at the ground well mouth are connected with the hydraulic oil pipe, which enters into the shaft oil pipe to the middle or lower part of the pump cover for connection with the pump cylinder. The utility model has the advantages of reasonable design, simple structure, reliable mechanical performance, low failure rate, small unit volume so as to reduce the field occupation, saving energy, safety, high efficiency and low cost.
Description
Technical field
The utility model belongs to pump, particularly a kind of long-range hydraulic driving down-hole oil production pump.
Background technique
Traditional well recovery pumping unit is to drive the reciprocal tractive sucker rod of lever by motor by rocker-arm link to constitute, and is commonly called as the machine of kowtowing.This equipment is widely used in the oil recovery field, technology maturation, and its structural principle does not have to change substantially for a long time.This and the relative development of mechanical ﹠ electrical technology at present generally adopt today of new high-tech technical development incompatible, and its deficiency manifests gradually, as existing mechanical equipment is very huge, cost is high, rate of fault is high, energy consumption is big etc.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of long-range hydraulic driving down-hole oil production pump is provided.
Long-range hydraulic driving down-hole oil production pump of the present utility model is in the lower end of oil well oil conduit the reciprocating oil-well pump formation to be installed, and the last pump cover screw thread of the lower end mouth of oil pipe and oil well pump is connected.The lower end of last pump cover successively screwed connection last short circuit, pump cylinder, short circuit, pump cover, pump head and oil nozzle down down.The upper/lower terminal mouth of pump case sleeve pipe respectively with upper and lower pump cover mutually intussusception fix.The positive negative frequency oil hydraulic pump outlet PRESSURE PIPE of being located at well head ground connects hydraulic oil pipe, and hydraulic oil pipe enters in the pit shaft oil pipe, is connected with pump cylinder down to pump cover.
As further improvement of the utility model, wherein the embedded popple type plunger of pump cylinder is provided with ball check valve in the pump head, is provided with ball check valve in the following pump cover.
Further improve as the utility model, wherein the oil-feed duct of oil nozzle through one-way valve enter down the side opening of the one-way valve of pump cover, the duct that enters pump cover in the annular space of pump case sleeve pipe, the up connection again enters in the oil pipe.
Described ground hydraulic pump is to have connected leading screw, plunger in succession by thrust shaft block, and plunger enters in the cylinder body through gland, and the outlet of cylinder body connects PRESSURE PIPE.
The working principle of long-range hydraulic driving down-hole oil production pump of the present utility model is to provide the hydraulic pressure frequency by the hydraulic reciprocating pump of being located at ground, this hydraulic pressure frequency is the positive and negative waveform power source of pulsed, transfer to the reciprocating pump pumping unit of being located at pit shaft oil pipe lower end through hydraulic tube, the plunger in the pumping unit oil hydraulic cylinder is also along with the positive negative frequency of hydraulic pressure is back and forth moved.During negative pressure, plunger is up, and the non-return valve in the following pump cover cuts out, and the non-return valve in the pump head is opened, and crude oil enters in the pump housing chamber from the duct of oil nozzle.During malleation, plunger is descending, and the non-return valve in the pump head cuts out, and squeezes into down the endoceliac crude oil of pump in the pump cover and its one-way valve is opened, and oil flows from its side opening and enters annular space and continue uply, enters in the pit shaft oil pipe through the duct, until the ground well head.So go round and begin again and back and forth move, make oil extraction continuously.
Long-range hydraulic reciprocating pump pumping unit of the present utility model and the particularly supporting use of horizontal well of oil recovery well can realize that the super large stroke recovers the oil, and this model utility has replaced traditional rocker-arm link reciprocal reciprocating oil pumping of being located at ground machine of kowtowing fully from equipment and on the method.
Long-range hydraulic driving down-hole oil production pump of the present utility model is reasonable in design, simple in structure, reliable in mechanical performance, rate of fault is low, equipment volume is little, reduced land seizure, has advantages such as energy-conservation, safe, efficient, low cost.
