Abstract
The invention relates to a depressurizing and charging device for an oil production well, which is characterized in that a depressurizing hydraulic distribution device is installed on an oil production pipe column; the oil production pipe column and the depressurizing hydraulic distribution device are arranged in a sleeve; the depressurizing hydraulic distribution device and the sleeve are matched and sealed; the sleeve is divided into an upper cavity and a lower cavity by the depressurizing hydraulic distribution device; the lower part of the oil production pipe column is in communication with the lower cavity; an oil layer is in communication with the lower cavity; the outlet end of the oil production pipe column is in communication with an oil separating and dosing device; the charging pipe of the oil separating and dosing device is in communication with the upper cavity; and the upper cavity and the lower cavity form two pressure systems resulting from the division of the sleeve into the upper cavity and the lower cavity by the depressurizing hydraulic distribution device. The depressurizing and charging device has depressurizing and throttling functions, which ensures that the pressure in the lower cavity is close to that in the oil layer, so that added liquid containing viscosity reducing drugs can not enter the oil layer, and the oil layer is prevented from being polluted; and as the added liquid entering the lower cavity is mixed with thick oil flowing out of the oil layer, the viscosity of the thick oil is reduced, the fluidity of the thick oil becomes better, and the thick oil can smoothly enter the oil production pipe column and be taken out. Therefore, the depressurizing and charging device for the oil production well has the beneficial effects of ensuring regular production in the oil well, improving oil well production and bringing about remarkable economic benefit of the thick oil well.
Description
Technical field
The present invention is the device that oil-field thick-oil well oil recovery viscosity reduction is used, and is a kind of producing well decompression liquid-adding device.
Background technology
The producing well oil that has is very thick, and is mobile poor, need to adopt the measure of dosing viscosity reduction well-flushing that its viscosity is descended after the ability ordinary production; But because formation pressure is low; The pit shaft back pressure that the viscosity reduction liquid that adds produces is stressor layer above Ground, and oil layer pollution is caused on the viscosity reduction liquid stratum of can bleeding; Well oil output is descended or stopping production, produce heavy economic losses.
Summary of the invention
The objective of the invention is to design a kind of producing well decompression liquid-adding device, make its viscosity reduction liquid can not get into the stratum, prevent oil layer pollution, avoid economic loss.
The objective of the invention is to realize like this: comprise the decompression liquid dispenser, the decompression liquid dispenser is installed on the flow string, and flow string, decompression liquid dispenser are lowered in the sleeve pipe; Decompression liquid dispenser and sleeve pipe fitted seal; The decompression liquid dispenser is divided into epicoele and cavity of resorption with sleeve pipe, flow string bottom and cavity of resorption UNICOM, oil reservoir and cavity of resorption UNICOM; The flow string port of export and the fuel-displaced chemicals dosing plant UNICOM that separates, the liquid-feeding tube of fuel-displaced separation chemicals dosing plant and epicoele UNICOM.
Fuel-displaced separation chemicals dosing plant comprises and separates that filling, liquid-feeding tube, drug discharging tube, drug storage filling, gutter, water storage are irritated, flowline, and UNICOM is irritated with separating in the flow string upper end, separates to irritate top flowline is installed; Separating the filling bottom fixes a drainpipe; Gutter and water storage are irritated UNICOM, and water storage is irritated the bottom liquid-feeding tube is installed, and drug discharging tube is installed on the liquid-feeding tube; The other end of drug discharging tube is installed in the bottom that drug storage is irritated, liquid-feeding tube one end and epicoele UNICOM.
Flow string upper outlet end is installed flow transmitter, and interstage valve is installed on the liquid-feeding tube, and flow transmitter is connected with interstage valve.
The invention has the beneficial effects as follows: the decompression liquid dispenser is divided into epicoele and cavity of resorption with sleeve pipe, makes epicoele and cavity of resorption become two pressure systems, and the decompression liquid dispenser has the decompression throttling action; Cavity pressure and formation pressure are approaching under guaranteeing, therefore, the adding liquid that contains the viscosity reduction medicine can not get into oil reservoir; Can prevent oil layer pollution, the adding liquid that gets into cavity of resorption mixes with the viscous crude that oil reservoir flows out, and viscosity of thickened oil descends; Flowability improves, and can get into flow string smoothly by extraction, oil well ability ordinary production; Can improve oil well output, make heavy oil wells have remarkable economic efficiency.
Description of drawings
Fig. 1 is the sketch map of the embodiment of the invention.Among Fig. 11 is meant all devices composition in the phantom wire frame.
The specific embodiment
Below in conjunction with Fig. 1 embodiments of the invention are described.
Can know that by figure comprise decompression liquid dispenser 4, decompression liquid dispenser 4 is installed on the flow string 3; Flow string 3, decompression liquid dispenser 4 are lowered in the sleeve pipe 2, decompression liquid dispenser 4 and sleeve pipe 2 fitted seal, and decompression liquid dispenser 4 is divided into epicoele 6 and cavity of resorption 7 with sleeve pipe 2; Flow string 3 bottoms and cavity of resorption 7 UNICOMs; Oil reservoir 5 and cavity of resorption 7 UNICOMs, flow string 3 ports of export and fuel-displaced chemicals dosing plant 1 UNICOM that separates, the liquid-feeding tube of fuel-displaced separation chemicals dosing plant 1 and epicoele 6 UNICOMs.Fuel-displaced separation chemicals dosing plant 1 comprises separating irritates 1-3, liquid-feeding tube 1-4, drug discharging tube 1-5, drug storage filling 1-6, gutter 1-7, water storage filling 1-8, flowline 1-9; 1-3 UNICOM is irritated with separating in flow string 3 upper ends; Separate to irritate 1-3 top flowline 1-9 is installed, separate and irritate the 1-3 bottom 1-7 that fixes a drainpipe, gutter 1-7 and water storage filling 1-8 UNICOM; Water storage is irritated the 1-8 bottom liquid-feeding tube 1-4 is installed; Liquid-feeding tube 1-4 goes up drug discharging tube 1-5 is installed, and the other end of drug discharging tube 1-5 is installed in the bottom that 1-6 is irritated in drug storage, liquid-feeding tube 1-4 one end and epicoele 6 UNICOMs.Further measure of the present invention is that flow string 3 upper outlet ends are installed flow transmitter 1-1; Liquid-feeding tube 1-4 goes up interstage valve 1-2 is installed; Flow transmitter 1-1 is connected with interstage valve 1-2, and when flow string 3 not during fluid, flow transmitter 1-1 passes to interstage valve 1-2 with signal; It is complete that interstage valve 1-2 is closed, and in well, do not add viscosity reduction liquid.
During production run; Extraction liquid flow to 1 li of fuel-displaced separation chemicals dosing plant from flow string 3; In separating filling 1-3, carry out water-oil separating then, the oil of separating is drained through flowline 1-9, and the water of separating flow to water storage through gutter 1-7 and irritates 1-8; Water storage is irritated 1-8 and is also had heating function, can the water that drain into water storage filling 1-8 be heated.After handling, the water that water storage is irritated 1-8 flow to liquid-feeding tube 1-4 again; Mix epicoele 6 interior storages that the back adds sleeve pipe 2 with the viscosity reduction Ji that drug storage filling 1-6 flows out; Mixed liquor flows in the cavity of resorption 7 of sleeve pipe 2 after the 4 decompression throttlings of decompression liquid dispenser, and mixes its viscosity reduction with the viscous crude of oil reservoir 5 outflows.
