Abstract
The utility model belongs to the field of the oil extraction device of the pumping well, and relates to a vacuum negative pressure production assembly. The utility model comprises an oil sleeve, an oil pumping pipe column, an air exhauster, an oil-well pump, a valve, a fluid flow meter and relevant pipelines. The oil pumping pipe column is arranged in the oil sleeve which is connected with the pumping well. The oil pumping pipe column is communicated with a vacuum container by the pipelines, and the vacuum container is communicated with the air exhauster and the oil-well pump via an air inlet pipe and an oil pipeline. Making use of the vacuum negative pressure theory to extract the oil in hyposmosis stratum is beneficial to the accumulation and the exploitation of the crude oil in the bottom of the low voltage and low yield oil well. So the daily output of the crude is improved. Furthermore, the hypotonicity oil layer can be exploited and used sufficiently to increase the oil production. The utility model has advantages of simple structure, economy, practicality, easy use and safety. The utility model is suitable for rebuilding or installing the national hypotonicity oil field and the low voltage and low yield oil well.
Description
Technical field
The utility model belongs to the extracting device of oil field of pumpingh well, relates to a kind of negative pressure of vacuum extracting device of oil.
Background technology
Conventional mechanical oil recovery is that oil extraction pump is arrived by below the producing oil liquid level down, must guarantee that promptly oil extraction pump has certain submergence, oil exploitation could be come to ground.But for China hypotonicity oil field, conventional mechanical oil recovery is incompetent, thereby many hypotonicity oil reservoirs are not also exploited normally and utilized.
Summary of the invention
It is a kind of with the oil storage tank negative pressure that is evacuated that the purpose of this utility model is to provide, and utilizes the crude oil of negative pressure of vacuum suction low permeability pay, increases the negative pressure of vacuum extracting device of oil of oil production.
The technical solution adopted in the utility model: a kind of negative pressure of vacuum extracting device of oil, comprise oil jacket, pumping pipe string, air exhauster, oil well pump, valve, fluid flowmeter and associated pipe thereof, pumping pipe string is arranged in the oil jacket, oil jacket is communicated with pumpingh well, its pumping pipe string is by the pipeline connection vacuum storage tank, and vacuum storage tank is communicated with air exhauster, oil well pump by air inlet pipe, petroleum pipeline.The oil pumping control valve is installed on the pumping pipe string, outlet valve is installed on the oil jacket.One way valve, fluid flowmeter are installed on pipeline, the air inlet pipe.Air exhauster is provided with stack.Draining valve is installed on the oil well pump.Oil transportation control valve, fluid flowmeter are installed on the petroleum pipeline.
The utility model utilizes the negative pressure of vacuum principle to extract the low permeability formation oil, helps the gathering and the extraction of low-voltage and low-yield oil well shaft bottom crude oil, improves crude oil day constant rate of production rapidly; Make the hypotonicity oil reservoir be exploited fully and utilize, increase oil production; The utility model is simple in structure, and is economical and practical, easy to use, safe, is suitable for domestic hypotonicity oil field, the transformation of low-voltage and low-yield oil well is installed and used.
