Abstract
The invention relates to a hydraulic reciprocating piston two-way oil production machine, which comprises a hydraulic station, a wellhead hydraulic cylinder, a connection pipe, a four-way wellhead, a well casing and an oil extraction pump. Two hydraulic pipes on the hydraulic station are respectively communicated with the upper and the lower sides of the wellhead hydraulic cylinder. A wellhead hydraulic piston in the wellhead hydraulic cylinder is connected with an oil extraction pump piston in the oil extraction pump cylinder through a connection rod. The lower end of the wellhead hydraulic cylinder is connected with the upper end of the four-way wellhead through the connection pipe, and the lower end of the four-way wellhead is connected with the oil extraction pump cylinder and an oil extraction pump pipe body through the well casing. The lower end and one side of the oil extraction pump cylinder is provided with an oil inlet (outlet), and an oil inlet on the lower end is provided with a retaining sealing ball. The oil extraction pump pipe body is connected with the oil extraction pump cylinder, one side is provided with an oil inlet, and an oil conveying passage and a one-way sealing ball are arranged inside the oil extraction pipe body. The oil production machine has the advantages of small land occupation area, low power consumption, convenient maintenance, long service life and high oil production, can reduce the energy consumption by 50 percent compared with the prior art, and can double the oil yield.
Description
One, technical field: the present invention relates to oil production equipment, particularly a kind of hydraulic reciprocating piston two-way oil production machine.
Two, background technology: existing overarm formula oil production machine and screw pump oil production machine are the ground machine transmission, and floor space is big, the power consumption height, and maintenance cost is expensive, and oil production is low; Electric submersible pumping is because the pump housing is big, and hole diameter is thick, and the cable price is also expensive, the cost for oil production height.
Three, summary of the invention: for overcoming technological deficiencies such as the above-mentioned floor space that has oil production machine now is big, power consumption is high, maintenance is expensive, oil production is low, the invention provides a kind of hydraulic reciprocating piston two-way oil production machine, it comprises Hydraulic Station, wellhead hydraulic cylinder, tube connector, four-way well head, well casing and oil extraction pump.Two hydraulic tubes on the Hydraulic Station communicate with the upper and lower side of wellhead hydraulic cylinder respectively.Well head hydraulic piston in the wellhead hydraulic cylinder joins by the oil extraction pump piston in connecting rod and the oil recovery pumping cylinder.The wellhead hydraulic cylinder lower end joins by tube connector and four-way well head upper end, and four-way well head lower end joins by well casing and oil recovery pumping cylinder and oil extraction pump body.An oil recovery pumping cylinder lower end and a side are provided with inlet (outlet), and the lower end oil-in is provided with the one-way sealing ball.Oil extraction pump body and oil recovery pumping cylinder join, and a side is provided with oil-in.Be provided with oil transportation channel and one-way sealing ball in the oil extraction pump body.
Operating principle: during work, the last hydraulic tube of Hydraulic Station is toward the interior delivery hydraulic pressure of wellhead hydraulic cylinder, and it is descending to promote the well head hydraulic piston, and it is also descending that connecting rod promotes the oil extraction pump piston.This moment, the one-way sealing ball A of oil extraction pump cylinder body lower end shut oil-in A.The oil of oil extraction pump piston bottom is forced through oil-out B one-way sealing ball B is backed down, and enters oil transportation channel again and enters well casing by oil-out D and export from the four-way well head.Simultaneously, because oil extraction pump descent of piston oil recovery pumping cylinder internal upper part negative pressure, subterranean oil backs down one-way sealing ball C by oil-out C from oil-in E and enters in the oil recovery pumping cylinder.On the contrary, instantly hydraulic tube during delivery hydraulic pressure, it is up to promote the well head hydraulic piston in the wellhead hydraulic cylinder.At this moment, one-way sealing ball B choke-out, one-way sealing ball A opens, and subterranean oil enters in the oil recovery pumping cylinder from oil-in A.Simultaneously, the oil of oil recovery pumping cylinder inner carrier epimere is forced in the oil recovery pump line from oil-out C, and one-way sealing ball C choke-out, one-way sealing ball D are opened, and oil enters well casing from oil-out D and also exports from the four-way well head.Reciprocal thus, two-way oil production.Because take that above-mentioned technical solution, beneficial effect of the present invention are that floor space is little, low in energy consumption, just maintenance, long service life, oil production height, can save energy half than prior art, oil production doubles.
Four, description of drawings: Fig. 1 is a structural representation of the present invention.
Five, the specific embodiment: below in conjunction with accompanying drawing, the present invention is further elaborated.Referring to Fig. 1 as can be known, hydraulic reciprocating piston two-way oil production machine comprises Hydraulic Station, wellhead hydraulic cylinder, tube connector, four-way well head, well casing and oil extraction pump.Two hydraulic tubes on the Hydraulic Station 1 communicate with wellhead hydraulic cylinder 2 upper and lower sides respectively, and the well head hydraulic piston 3 in the wellhead hydraulic cylinder 2 joins by the oil extraction pump piston 9 in connecting rod 4 and the oil recovery pumping cylinder 8.Wellhead hydraulic cylinder 2 lower ends join by tube connector 5 and four-way well head 6 upper ends, and four-way well head 6 lower ends join by well casing 7 and oil recovery pumping cylinder 8 and oil extraction pump body 12.Oil recovery pumping cylinder 8 lower ends are provided with oil-in 11A, and a side is provided with inlet (outlet) 11B, 11C, 11D, and oil-in 11A is provided with one-way sealing ball 10A.Oil extraction pump body 12 joins with oil recovery pumping cylinder 8, and a side is provided with oil-in 11E.Be provided with oil transportation channel 13 and one- way sealing ball 10B, 10C, 10D in the oil extraction pump body 12.
