Abstract
The present invention relates to a pneumatic jet pump for liquid production, which is composed of a center nozzle, an air duct, an air duct manifold, a pumping chamber, a throat, a diffusion pipe, etc. without a reciprocating component. The present invention has the advantages of simple structure, compactness, long service life, convenient operation and few maintenance workload, and is suitable for deep well liquid production and especially suitable for the oil production of oil wells of oil fields.
Description
The invention belongs to the air pressure jet flow pump.In the domestic test of once reporting the fluidics oil recovery of sixties Mo.After entering the seventies, advanced countries such as the U.S., the Soviet Union successively utilize the fluidics production of recovering the oil, and progressively promote, and this indicates that Jet injector enters the practical stage in oil producing operation.
Interrelated data report China units concerned also carry out the research of Jet injector in deep-well water lift and oil recovery.The hydraulic jets pump of China's Renqiu oil field development has carried out production testing, illustrates that fluidics has begun to use in production is recovered the oil in China oil field.
The major advantage of Jet injector is the reciprocating member that does not have close fit, and is not fragile, is applicable to bad working environment; Simple in structure, compact, form by workpieces such as central nozzle, air pipe, air guide menifold, truncated cone suction chamber, cylindrical trunnion and the diffusing tubes of falling the truncated cone, easy to operate, the life-span is long, maintenance load is few.Applying of overslaugh Jet injector is that Jet injector itself exists two major defects at present: (1) causes Jet injector must have higher suction pressure owing to the cavitation erosion problem, ground pressure equipment energy consumption height; (2) pump efficiency is lower, causes the input power on ground than common hydraulic piston pump height.Along with the improvement of Jet injector structure, the improving constantly of pump efficiency is also because the advantage that Jet injector itself is given prominence to, so, significance in oil producing operation is familiar with by people gradually, and the promotion and application in developed country are paid much attention to as a kind of new and high technology.
The Jet injector of oil producing operation application at present is divided into two classes.One class hydraulic jets pump forms jet with high voltage power liquid, drives Jet injector work.Another kind of is the air pressure jet flow pump, utilizes pressurized gas to be used as power, and forms jet and drives Jet injector work.The simple working principle of Jet injector is as follows: when highly pressurised liquid or gas when air guide menifold, air pipe are sprayed at a high speed by central nozzle, near the generation the low pressure area inner and nozzle at the suction chamber of the Venturi tube of Jet injector (or claiming Laval nozzle), thereby formation pumping action, take away the liquid stream that oozes out on the stratum, at this moment mixed solution or gas-liquid mixture partly enter diffuser by trunnion at a high speed, upwards lifting.Adopt plural serial stage, connect one-level as the relay race one-level buried crude oil in the depths, stratum is risen on the ground.
Fig. 1 is the working principle schematic representation of jet pumping, (1) Jet injector wherein, in oil pipe, press certain distance and install one, (2) ground power unit of generation highly pressurised liquid or gas, (3) oil pick-up tube, (4) oil well casing, (5) are installed on the packing annulus piece between oil well casing and the oil pick-up tube, seal, do not allow highly pressurised liquid or gas run into the stratum.
U. S. Patent 4083660 has been introduced the structural type of relevant gas jet pump.First kind of Jet injector structure is as follows, one taper suction chamber is arranged at pump housing center, several nozzles that shrink to the center are distributing on suction chamber, it below suction chamber a lifting auxiliary device (being equivalent to a kind of one-way valve), this auxiliary device is by menifold, and inverted cone valve ball seat and valve ball are formed.Obvious this pneumatic pump structure is very complicated, and several nozzle difficulty of processing are big, and labor content is also big, and nozzle is many, air-flow is not concentrated, and pump efficiency is low.
As to above-mentioned relatively backward architecture advances, this patent has been introduced a kind of improved air pressure jet flow pump again, and its structure is as follows: the Venturi tube of Jet injector is formed by truncated cone diffusing tube, trunnion with by the suction chamber that curved surface constitutes.A central nozzle is installed in suction chamber, and central nozzle communicates with streamlined chevron shaped menifold.After high pressure draught imports the central nozzle high velocity jet from chevron shaped menifold, near nozzle, form low pressure area, this moment, suction chamber formed pumping action, the oil gas mixed solution is sucked trunnion by ring pipe, enter diffuser, further mix at diffuser oil gas mixed solution, rise along oil pipe reposefully, in order to improve pump efficiency, between per two Jet injectors, increase the filter screen device of a multilayer, gas-liquid is fully mixed.
Obviously above-mentioned Jet injector has a kind ofly been done significant improvement than preceding on structure and pumping efficiency, become a central nozzle from a plurality of nozzles, pump efficiency has improved, but the difficulty of processing of annular pass and streamlined herringbone menifold curved surface suction chamber is big, shape is also complicated, and labor content is also big.
Purpose of the present invention is further simplified the air pressure jet flow pump structure, reduces difficulty of processing and workload, further improves the efficient of pump.Trunnion is one of essential elements of Jet injector, processes highly polishedly, and between the 700mm, sometimes even longer, generally the ratio of Jet injector central nozzle sectional area and trunnion cross section is 1 to the length of throat of general Jet injector: between the 1-2.7 at 300mm.Technological scheme of the present invention is:
