Abstract
The present invention relates to pressurized water-filling method and device thereof in the well of oil field, be characterized in utilizing the supercharging device pressurized water injection under water injection well, supercharging device uses pump, especially plunger water injecting pump, have and do not leak, pollution-free, energy-conservation, pump efficiency advantages of higher is without the ground water flooding pump station.This apparatus structure is simple, and low price has only the 1/4-1/10 of conventional waterflooding pump valency.Be highly suitable for the piecemeal well group exploitation of little oilfield and elephant.
Description
The invention belongs to oil-field flooding technology and equipment, be particularly useful for the piecemeal well group exploitation of little oilfield and elephant.
Present most Oilfield using waterflooding extraction, all have water flooding pump station to each water injection well dosing water filling than elephant, water injecting pump mostly is centrifugal multistage pump multiple centrifugal pump, multi-cylinder plunger displacement pump of big discharge capacity etc., build pumping plant to take up an area of, build a house, 24 hours on duty, very uneconomical, leakage accident appears sometimes.Find many block of cells near the oil field that has, many little fault blocks are also arranged in the oil field, they are not communicated with big block, only with several mouthfuls or tens mouthfuls of oil wells, often only need 1-2 mouth water injection well just can accelerate exploitation, this water injection well life cycle is short, sets up pumping plant and more seems uneconomical.
The purpose of this invention is to provide a kind of new water flood, this method do not leak, pollution-free, energy-conservation, economical, need not to set up ground pump station, and its apparatus structure is simple, low price, efficient height, convenient being suitable for.
Technical essential of the present invention is: the supercharging device pressurized water injection that in water injection well, directly adopts, and this supercharging device comprises pump and power set in the well, well pump can be used screw pump, electric submersible pump etc., the most handy plunger water injecting pump.Power set can place down-hole or ground, all can with existing oil pumper and simple and easy power set.The plunger water injecting pump can be used pressure lever type plunger water injecting pump or rod-pulling type plunger water injecting pump, and the former has pump barrel, depression bar, plunger and two one way valves that link to each other with pump barrel and plunger respectively.The latter has pull bar, packing chamber, the outlet pipe that shunting saves and pump barrel is connected and two one way valves that link to each other with pump barrel, plunger that pump barrel links to each other with plunger.
Because apparatus of the present invention are simple in structure, low price, the efficient height, convenient being suitable for, thus do not need to set up the big and complicated ground pump station of investment, and leakage accident can not appear, energy-conservation, pollution-free.In order to realize the very fast exploitation of a block or a well group crude oil, often oil production equipment is wherein rolled over and removed, change water injection well, connect the pipeline of water flooding pump station, the present invention can utilize original mechanical oil recovery equipment fully, only need to change the pump housing and can make flow process reverse, reach purpose to oil-bearing stratum flooding.Application the present invention recovers the oil, and convenient, flexible, cost is low, can improve oil recovery efficiency and oil yield greatly.The present invention also can be used for the exploitation of natural gas etc.
Fig. 1 is a depression bar plunger water injecting pump example structure schematic diagram.
Fig. 2 is a rod-pulling type plunger water injecting pump example structure schematic diagram.
Among Fig. 1, the 1st, depression bar, the 2nd, the water injection pipe box cupling, the 3rd, production string, the 4th, water injection pipe, the 5th, plunger, the 6th, the water filling pump barrel, the 7, the 8th, the one way valve that direction is opposite, 9 is upper packer, and 10 is ported sub, and 11 is lower packet, and 12 is the water injection pipe plug, 13 is oil-water-layer.
Referring to Fig. 2, the 14th, with the pull bar that reciprocating power set link to each other, water flows into the shunting joint 18 from water injection pipe 15, when pull bar 1 rises, water enters in the pump barrel 23 by one way valve 24, and pull bar 1 descends, and the plunger 20 that links to each other with it descends, valve 24 cuts out, water enters in the plunger by valve 22, and when pull bar 1 rose, the water in the plunger entered in the oil reservoir by hole on the plunger and the outlet pipe 19 that is connected with former pump 23, the packing chambers for sealing 17,16,21 are respectively upper and lower packer.
