Abstract
The utility model belongs to the technical field of oil pumping machinery and relates to a viscosity reduction pump. A pump cylinder assembly is connected with a plunger assembly which is connected with a fixed valve base connector. The fixed valve base connector is connected with a fixed valve assembly. A viscosity reduction agent conveying pipe is connected with the fixed valve base connector. A single-way constant pressure valve is arranged on the viscosity reduction agent conveying pipe. The viscosity reduction pump has the advantages that stratum liquid supply capacity is not affected, methods such as chemical agent viscosity reduction, water heat catalytic cracking viscosity reduction, thinly-mixed viscosity reduction and microorganism viscosity reduction can be used, the crude oil physical property is changed at a crude oil extraction and conveying source, and crude oil extraction is convenient.
Description
Technical field
The utility model relates to a kind of viscosity reduction pump, belongs to oil pumping field of mechanical technique.
Background technique
Viscous crude refers to that under reservoir temperature viscosity is greater than the degassed crude of 100mPas, but on-the-spot viscosity of thickened oil is conventionally all more than 100mPas.
Viscous crude has the outstanding features such as viscosity is high, density large, poor fluidity.The high viscosity of viscous crude is mainly mutually tangled and is caused due to solvable pitch particle, in the exploitation of viscous crude with collect in defeated process, causes the mobility variation of crude oil in pit shaft and ground oil conduit.Viscous crude can flow at oil reservoir, flow into pit shaft in oil pipe on while flowing, because ground temperature constantly reduces, viscosity of crude constantly rises, flow resistance increases thereupon, extraction and difficulty of transportation.
Therefore reduce viscosity of thickened oil, improve the mobility of viscous crude, be solution thickened oil recovery, collect defeated key.
Existing oil well pump adopts whole core structure, and crude oil does not have viscosity reduction passage after entering pump;
Existing product is not for the pipeline of reducing thick oil viscosity, so can not carry out viscosity reduction to underground viscous crude targetedly in oil pumping process;
If directly reinforced to stratum from other pipelines, likely change stratum permeability, affect fluid supply capacity.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of viscosity reduction pump.
A pump, pump barrel assembly connects plunger piston assembly; Plunger piston assembly is connected and fixed valve base joint, and fixed valve base joint is connected and fixed valve assembly; Viscosity depressant delivery pipe is connected and fixed valve base joint; On viscosity depressant delivery pipe, there is an one-way constant pressure valve.
The utility model has the advantages that and do not affect stratum fluid supply capacity, can adopt chemical agent viscosity reduction, hydrothermal catalytic cracking viscosity reduction, mix the methods such as rare viscosity reduction and microorganism viscosity reduction, from crude oil extraction, change crude oil property with carrying source, facilitate crude oil to adopt and take out.
