Description
Technical field
The utility model relates to a kind of heavy crude petroleum well and mixes conveying device, relates in particular to a kind of hollow rod down-hole and mixes defeated energy saver.
Background technology
In the numerous oil fields of China, have a large amount of heavy oil wells, the production of current more heavy oil wells adopts electrical heating process and tubing and casing annular space to mix two kinds of modes of sewage collection transmission.Electrical heating refers to that a kind of oil pipe and sleeve pipe of utilizing directly heats the method for crude oil in oil pipe as heater, electric energy is sent to oil pipe by Three-Phase Distribution Transformers through the output of AC-DC-AC inverter circuit, tubing and casing contactor through oil pipe bottom is connected to sleeve pipe, form a complete loop, utilize oil pipe to do heat source body, become heat energy directly to heat the liquid in pit shaft electric energy conversion, its energy consumption is large, expense is high, waste electric power resource; Tubing and casing annular space is mixed sewage collection transmission and is referred to a kind of toward the interior hot water that injects of tubing and casing annular space, lifting by sucker rod makes the water mixing mix with crude oil, by pump, make mixed liquor be lifted to well head, collect defeated, but this method crude oil lifting resistance is large, beam-pumping unit jig frequency is low, yield poorly, from sleeve pipe, mix causing greatly and easily and coagulate the shortcomings such as stifled along journey heat waste of hot sewage.
Summary of the invention
The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of hollow rod down-hole to mix defeated energy saver.
Defeated energy saver is mixed in hollow rod of the present utility model down-hole, by high-pressure hose, strainer, water filling three way cock, down-hole is mixed defeated ball-and-seat and is formed, the entrance pipe of device is provided with pipeline reducing diameter I, pipeline after reducing is connected to strainer through high-pressure hose, the output pipe of strainer is provided with flow meter, the two ends of flow meter are provided with pipeline reducing diameter II and pipeline reducing diameter III, pipeline after reducing is connected to water filling three way cock through high-pressure hose, the other end of water filling three way cock connects hollow polished rod, hollow polished rod and hollow rod are end to end, the afterbody connecting downhole of hollow rod is mixed defeated ball-and-seat, the output of mixing defeated ball-and-seat is connected to well head pipeline.
As further improvement of the utility model, described pipeline reducing diameter I is that 50 * 20 reducings, pipeline reducing diameter II are that 20 * 15 reducings, pipeline reducing diameter III are 15 * 20 reducings.
As further improvement of the utility model, described pipeline reducing diameter III and the pipeline between high-pressure hose 4 are provided with dosing branch road.
As further improvement of the utility model, described strainer is provided with pressure meter and thermometer.
Defeated energy saver is mixed in hollow rod of the present utility model down-hole, be applicable to have the heavy oil block of certain fluid supply capacity, it utilizes existing thermal source by original intensification, use hollow polished rod and hollow rod that hot sewage is fully mixed with crude oil, strengthen its mobility, and utilize water filling three way cock and down-hole to mix defeated ball-and-seat, avoided gas lock, improved pump efficiency, the use of this device has reduced crude oil lifting resistance, increased beam-pumping unit jig frequency, avoided that to mix causing greatly and easily along journey heat waste of hot sewage solidifying stifled due to sleeve pipe, and then reduced and produced liter originally, improved crude output.This device is also applicable to high viscous oil field simultaneously, to adding to become a mandarin in hot sewage by hollow stem with high viscous oil well, changes agent, and improvement downhole crude mobility is so that exploitation.
