Abstract
The invention discloses a downhole oil-gas separation experimental device, relates to a separation device and particularly relates to an experimental device for simulating downhole oil-gas separation. The device comprises a water storage tank, a gas-liquid mixer, an air compressor and a separator, wherein the water storage tank, the gas-liquid mixer and the separator are sequentially connected with one another, the air compressor is connected with the gas-liquid mixer, an emptying valve is arranged on the separator, and positions of outflow ports of the water storage tank, the air compressor, the separator and the emptying valve are respectively provided with a pressure gauge and a flow meter. According to the downhole oil-gas separation experimental device, gases and liquids are fully mixed and then enter the separator, the valve is adjusted to control the mixing ratio of the gases and the liquids, and the flow meters and the pressure gauges are used for detecting separation effects. The downhole oil-gas separation experimental device is simple in structure and high in practicability.
Description
Technical field
The present invention relates to a kind of tripping device is particularly related to a kind of for simulating the experimental provision of downhole oil-gas separation.
Background technology
Gas-oil separation is one of chief component of submersible electric pump, be used for separating the free gas in well liquid usually used as pump intake, to prevent that free gas from entering in pump, affect the normal operation of pump, and the key that relates to of peaceful tripping device is to improve the separation efficiency of pump, because the fluid numerical model of oil-gas separator biphase gas and liquid flow is described very complicated, although oil-gas separator structure is simple, but the relation between its structure and separation efficiency still can not be resolved theoretically, thereby how to utilize experiment to study the downhole oil-gas separation device and become an important research theme.
Summary of the invention
The present invention be intended to propose a kind of can simulation well under the separating experiment device of gas-liquid mixture.
A kind of downhole oil-gas separation test unit of the present invention, comprise water tank, air and liquid mixer, air compressor and separation vessel, wherein water tank, air and liquid mixer, separation vessel connect successively, pore compressor and air and liquid mixer interconnect, described separation vessel is provided with exhaust-valve, and the flow export place of described water tank, air compressor, separation vessel, exhaust-valve is equipped with tensimeter and flowmeter.。
Preferably, also be provided with valve between described water tank and air and liquid mixer.
Preferably, described air and liquid mixer inside also is provided with filter screen.
A kind of downhole oil-gas separation test unit of the present invention, gas-liquid enters in separation vessel after fully mixing, and control valve is controlled the mixing ratio of gas-liquid, by flowmeter and tensimeter, detects separating effect, and the present invention is simple in structure, and practicality is very strong.
The accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention 1.
In figure: the 1-water tank; The 2-air compressor; The 3-air and liquid mixer; The 4-separation vessel.
Embodiment
Embodiment 1.
A kind of downhole oil-gas separation test unit of the present invention, water is pumped liquid by centrifugal pump from water tank 1, by valve regulated fluid pressure and flow, utilize flow and the pressure of gauge measurement liquid simultaneously, then liquid flows into air and liquid mixer 3; Gas pumps into air and liquid mixer 3 by air compressor 2, the valve that the pressure of gas and flow are carried by air compressor 2 is regulated, utilize flow and the pressure of gauge measurement gas, after gas, liquid mixture fully mix in air and liquid mixer 3, enter separation vessel 4 after filtering out impurities by filter screen, liquid after the separation of separation vessel 4 returns to water tank 1 and recycles, the amount of liquid that utilizes flowmeter and gauge measurement to return, then the gas exhaust-valve is emptying, utilize the flowmeter of exhaust-valve and gas flow and the pressure size that gauge measurement is discharged.
