Description
Technical field
The utility model relates to a kind of oil pumper, is specifically related to a kind of combined type multiple well pumping unit, belongs to crude oil mining equipment technical field.
Background technology
Oil pumper is one of main ground installation of extraction down-hole, oil field crude oil, and the oil pumper of countries in the world more than 90% all is beam pumping unit at present.It is by quadric chain, drives downhole pump the pumping of cycle that fix, thereby realizes the oil pumping purpose.Though beam pumping unit has reliable operation, the advantage of being convenient to manage, but based on its mechanism principle, the oil pumper of this kind mechanism is bulky, energy consumption is high, load performance is poor, and every oil pumper can only carry out oil exploitation to individual well, can not be simultaneously to the operation of pumping of two mouthfuls of oil wells, exploit oil well more than two mouthfuls simultaneously as need, must set up a cover oil pumper equipment in addition, be difficult to satisfy the needs of oil field oil production technology.
On the other hand, existing beam pumping unit is in the oil pumping operation process, and downhole pump has only the stroke of half extracting crude oil, and second half stroke is an oil-absorbing process, so just causes crude oil discontinuity to flow out, and influences yield of unit time and benefit.
Summary of the invention
The purpose of this utility model is: providing a kind of can carry out oil producing operation to many mouthfuls of oil wells simultaneously, and can guarantee that the continuity that extracts crude oil flows out, and reduces the equipment and the capital investment in oil field; Big to solve existing oil pumper energy consumption, the cost for oil production height can not carry out oil producing operation to two mouthfuls of oil wells simultaneously, is difficult to satisfy the combined type multiple well pumping unit of oil field oil production technology needs problem.
The utility model is to realize above-mentioned purpose by the following technical solutions:
A kind of combined type multiple well pumping unit, it is made of support A, support B, support C, power set, crank A, crank B, oil cylinder, oil cylinder piston bar and connecting rod, it is characterized in that: support B and support C are separately positioned on the both sides of support A, on the support A power set are installed, the top of support B and support C is separately installed with crank A and crank B, on the crank A drive is installed, drive is connected with power set by driving-chain, and crank A is connected by connector with crank B; The bottom of support B and support C is symmetry shape respectively and is provided with oil cylinder, and oil cylinder is connected with crank B with crank A respectively with connecting rod by the oil cylinder piston bar; Described oil cylinder one side is provided with flow string, and the two ends of flow string are provided with inlet valve and delivery valve.
The beneficial effects of the utility model are:
This combined type multiple well pumping unit both can be to the operation of single port oil well, also can carry out concentrated oil producing operation simultaneously to Liang Kou and the oil well more than two mouthfuls, thereby can significantly improve oil recovery efficiency, save time and the space, reduce the manufacturing cost of oil production equipment and the capital investment in oil field.This combined type multiple well pumping unit modern design, simple in structure, solved that existing oil production equipment is bulky, energy consumption is high, load performance is poor, and every oil pumper can only carry out oil exploitation to individual well, can not be simultaneously to the pump problem of operation of many mouthfuls of oil wells; And energy continuous drawing crude oil, transportation and easy for installation.Be specially adapted to concentrate in the zonule, oil field the use of recovering the oil.
Description of drawings:
Fig. 1 is a kind of structural representation of combined type multiple well pumping unit;
Fig. 2 is a kind of operating principle schematic diagram of combined type multiple well pumping unit.
Among the figure: 1, support A, 2, support B, 3, support C, 4, power set, 5, crank A, 6, crank B, 7, oil cylinder, 8, connector, 9, the oil cylinder piston bar, 10, connecting rod, 11, flow string, 12, inlet valve, 13, delivery valve, 14, drive, 15, driving-chain, 16, driver module, 17, the production module.
The specific embodiment:
This combined type multiple well pumping unit is made of support A1, support B2, support C3, power set 4, crank A5, crank B6, oil cylinder 7, oil cylinder piston bar 9 and connecting rod 10, support B2 and support C3 are separately positioned on the both sides of support A1, the top of support A1 is equipped with power set 4, and the top of support B2 and support C3 is separately installed with crank A5 and crank B6.Drive 14 is installed on the crank A5, and drive 14 is connected with power set 4 by driving-chain 15.
Crank A5 and crank B6 interconnect by connector 8, and the bottom of support B2 and support C3 is symmetry shape respectively and is provided with oil cylinder 7, and oil cylinder 7 is connected with crank B6 with crank A5 respectively with connecting rod 10 by oil cylinder piston bar 9.Each oil cylinder 7 one side of support B2 and support C3 bottom are respectively arranged with flow string 11, and the two ends of flow string 11 are respectively arranged with inlet valve 12 and delivery valve 13.Inlet valve 12 is used for being connected with oil well with oil storage tank (oil storage tank and oil well figure do not draw, referring to accompanying drawing 1) with delivery valve 13.
This combined type multiple well pumping unit is made of two parts, and a part is the driver module 16 that is made of power set 4, and another part is to go up production module 17(that symmetrically arranged oil cylinder 7 constitutes referring to accompanying drawing 2 by support B2 or support C3); The combination of production module 17 and driver module 16 can be selected different schemes according to the different situations (the interior pressure of oil well or the density of oil well) of oil well; Two production modules 17 and driver module 16 combination (referring to accompanying drawing 1) can be used to the four-hole well recovery for one.
The operating principle of this combined type multiple well pumping unit is: when pressure in the oil well was less than or equal to zero, oil pumper was under stopped status, and inlet valve 12 and delivery valve 13 are in closed condition; After the oil pumper start, when oil cylinder piston bar 9 moves upward under the effect of crank A5 or crank B6 and connecting rod 10, make and produce negative pressure in the oil cylinder 7, inlet valve 12 is opened, and crude oil enters oil cylinder 7 by oil country tubular good; When oil cylinder piston bar 9 ran to top dead centre, the pressure in the oil cylinder 7 was identical with oil well pressure, and inlet valve 12 cuts out under the effect of gravity automatically; When oil cylinder piston bar 9 is moved downwards by top dead centre under the effect of crank A5 or crank B6 and connecting rod 10, produce malleations in the oil cylinder 7 delivery valve 13 is opened, crude oil enters oil storage tank through delivery valve 13 and pipeline and stores.
The box-like oil pumper of these many well groups adopts 21 combining structures of two production modules 17 and 16 combinations of a driver module, has four work units, works under open state that it is separate to move between the unit, and the duty between the production module also is separate; By the connection angle of connector 8 adjustment crank A5 and crank B6, can make the duties of four work units differ four/one-period, thereby guarantee the continuity of former oil obtd.When four work units were inserted a bite well simultaneously, oil recovery efficiency can be multiplied.
This combined type multiple well pumping unit modern design, simple in structure, solved that existing oil production equipment is bulky, energy consumption is high, load performance is poor, and every oil pumper can only carry out former oil obtd to individual well, can not be simultaneously to the pump problem of operation of many mouthfuls of oil wells, be specially adapted to that concentrating in the zonule, oil field recovers the oil uses.
