Abstract
The utility model relates to a double-pump composite selective zone production device which is used for producing oil at selective zones in an oil field. The utility model is composed of plungers, pump barrels and an oil sucking rod. The difference of the diameters of the upper plunger and the lower plunger is a positive number, and the upper pump barrel and the lower pump barrel are connected by an eccentric check valve, a short joint and an oil pipe, wherein, the oil pipe is alternately connected with a telescopic head and a packer. The utility model solves the problems of complex procedure and high cost. The utility model has the characteristics of low cost, simple working procedure and long use period when the utility model achieves the same effect.
Description
The utility model relates to a kind of oil field development extracting device of oil, belongs to compound minute device for picking of double pump.
The oil field all needs to use devices such as hollow oil well pump, common tubing pump and hollow rod to the oil recovery well separate zone production time at present.Site operation labor intensity is big, complex procedures, and cost is very high, moreover pump detection period is short, is generally about eight months.
The purpose of this utility model is to avoid the deficiency of above-mentioned technology, and provides a kind of double pump compound minute device for picking.
The purpose of this utility model can reach by the following technical programs: this device is made up of oil pump plunger piston, oil well pump pump barrel and sucker rod, the diameter difference of oil pump plunger piston is a positive number up and down, link to each other with oil pipe by eccentric one-way valve, pipe nipple between the oil well pump pump barrel up and down, wherein oil pipe is connected with telescopic head and packet at interval.
The utility model has following advantage than above-mentioned prior art: because this device directly uses the oil pipe in the oil recovery well, and do not need to change hollow rod, cost reduces greatly, and labor intensity reduces a lot relatively; Moreover oil pipe connects telescopic head and packet at interval, makes oil reservoir be separated by packet, and the diameter difference of oil pump plunger piston is a positive number up and down in addition, can produce positive negative pressure when making operation, reaches the purpose of layering oil pumping.Secondly, because each parts of this device often do not damage, pump detection period can reach about 400 days, and operation is simple.
Accompanying drawing 1 is that structure of the present utility model is cutd open figure.
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, this device is by tubing pump plunger (8,2), tubing pump pump barrel (9,3), sucker rod 6 is formed, in the built-in sleeve pipe 1 of pump barrel (9,3), plunger (8,2) built-in pump barrel (9,3) in, the diameter of plunger 8 is greater than the diameter of plunger 2, plunger (8,2) link to each other with common sucker rod 6 between, reduced time and the expense of changing hollow rod; Link to each other with oil pipe 11 by eccentric one-way valve 7, pipe nipple 12 between pump barrel (9,3), wherein oil pipe 11 is connected with telescopic head 5 and packet 4 at interval, makes oil reservoir be separated by packet 4.
When using, can be according to reality, selecting plunger 8 diameters for use is 56mm, and plunger 2 diameters are 32mm or 38mm, as oil pump plunger piston (8, when 2) moving upward under external force, produce negative pressure, the valve of pump barrel 3 is washed open by oily stream, and the valve of eccentric one-way valve 7 also is opened owing to suction function simultaneously, the liquid of packet oil reservoir output about in the of 4 enters in the pump barrel (3,9) from plunger 2, one-way valve 7 respectively; When oil pump plunger piston (8,2) when moving downward under external force, produce malleation, the valve of valves and eccentric one-way valve 7 is closed in the pump barrel 3, the valve of plunger (8,2) is washed open, and liquid enters in the oil pipe 11, along with the to-and-fro motion of plunger (8,2), liquid is pumped into ground by sucker rod 10.
As seen, this device only needs the logical tubing pump of two Daeporis, has simplified technology, when reaching identical effect, has reduced cost, and application will be better.
Claims (1)
1, a kind ofly relates to compound minute device for picking of double pump that the oil field branch is adopted, by plunger (8,2), pump barrel (9,3), sucker rod (6) is formed, it is characterized in that: the diameter difference of plunger (8,2) is a positive number, pump barrel (9,3) link to each other with oil pipe (11) by eccentric one-way valve (7), pipe nipple (12) between, wherein oil pipe (11) is connected with telescopic head (5) and packet (4) at interval.
