Abstract
The utility model relates to a multi-phase underground liquid-gas separator, which is a separating device used for separating gases from liquids during the practice of oil pumping in an oil well. The utility model has the benefits of improving the effectiveness of an oil-well pump and the productivity of the oil well. The separator mainly consists of a gas-outlet upper joint, an inner central pipe, an oil inlet welding ring, a gas-outlet central pipe, an outer cylinder, a blade, a gas overflow ring, a shunt head and a bottleneck lower joint. Designed in consideration of the principles of fluid mechanics as well as the physical characteristics of liquid and gas, the separator can separate gases from liquids by a three-phase process of contraction followed by expansion, centrifugation and gravitation. The on-site evidence suggests that the utility model has the advantages of reasonable structural design and high gas-liquid separation efficiency.
Description
Technical field
It is a kind of oil well oil-pumping when producing that the utility model relates to a kind of multiple formula down-hole liquid, gas separating device, with the separator of separating in the gas from liquid, belongs to the oil recovery wellbore tool in the petroleum machinery.
Background technology
At present, the down-hole liquid of the routine of field use, gas separating device adopt Gravity Separation, separation principle is simple, liquid, gas separative efficiency only 30%～35%, have a strong impact on pump efficiency and oil well output, be difficult to satisfy the needs of oil field development, the utility model carries out structure design according to the physical characteristics of fluid mechanics principle and liquid, gas, adopt triple separation such as compression-expansion, centrifugal and gravity, liquid gas separative efficiency can reach more than 80%.
Summary of the invention
The purpose of this utility model is to provide a kind of multiple formula down-hole liquid, gas separating device, overcomes the drawback of liquid under the conventional well, gas separating device, improves the efficient of down-hole liquid, gas separation, improves oil well output.
The utility model adopts following technical scheme, a kind of multiple formula down-hole liquid, gas separating device are made of exhaust top connection, inner central tube, oil-feed welding ring, exhaust center pipe, urceolus, blade, the compression ring that overflows, shunt head, bottleneck lower contact, it is characterized in that inner central tube and exhaust center pipe link together by the oil-feed welding ring; Last seal head and shunt head are welded on the upper/lower terminal of inner central tube respectively, excessive compression ring and lower sealing ring are welded on the upper/lower terminal of exhaust center pipe respectively, be contained in the urceolus, exhaust top connection and the screwed connection of bottleneck lower contact difference are at the upper/lower terminal of urceolus.
Multiple formula of the present utility model down-hole liquid, gas separating device are between top connection and seal head, between urceolus and joint ring, be separately installed with sealing ring between urceolus and lower contact.
Bottleneck lower contact inwall car of the present utility model has 75 ° convergency, forms bottleneck, is compressed through herein the time to guarantee liquid, gas mixture.Blade is welded on the inner central tube with helical form, guarantees that liquid, gas mixture produce centrifugal force through herein the time.Evenly be drilled with a plurality of apertures on the body of exhaust top connection, in order to isolated gas is discharged.
In the utility model when work, be connected the bottom of oil well pump with multiple formula down-hole liquid, gas separating device, down design attitude in the well.When oil well pump is opened, liquid, gas mixture in the well are introduced into multiple formula down-hole liquid, gas separating device, after separating through compression-expansion, centrifugal and gravity etc., to separate in the gas from liquid, and be discharged in the oil casing annular space, make gas not enter oil well pump, thereby realize improving the purpose of oil well pump pump efficiency and oil well output.
Multiple formula down-hole liquid, gas separating device according to the physical characteristics of hydrodynamics and liquid, gas, utilize computer software design on structure design, structure design is science, rationally more, and technology content is higher, and liquid, gas separative efficiency are higher.
