Abstract

The invention relates to the oil industry and m. used to separate gas from fluid in the well. The purpose of the invention is to increase the separation capacity by increasing the rate of gas release from oil. The gas separator includes a housing 2 with a screw 3 placed in it, a single pipe 4 with a return valve 5 entering the gas exhaust. On the working surface of the screw 3 there are windows 7, above which canopies 8 are alternately positioned in different directions relative to each other in the housing 3, where it receives a rotational motion. Gas is introduced from this liquid, which rises up through the window system 7, enters the pipe 4 and through the valve 5 enters the annular space. Due to the visors 8 in the separator, the acceleration of the oscillatory motion is superimposed on the acceleration of the rotational movement of the liquid. 1 il. i (L

I The invention relates to the oil industry and can be used to separate gas from liquid in a well.

The aim of the invention is to improve separation resistance for increasing the rate of separation of ase from oil.

The drawing shows the separator, General view.

Under bore 1 of the borehole pump (not shown), a housing 2 is installed, a gas separator, in which the auger 3 is located. The upper part of the screw 3 goes into the gas exhaust pipe 4, in which a check valve 5 is installed. Pneck 3 is a belt 6 seconds. windows cut in it 7. The windows are cut on three sides of the perimeter-1) and with the formation of peaks 8, 1 turns alternately in opposite (Sides. Tape 6 when placed in Case 2 is twisted along a helix. For entering the gas separator-top well liquids in the lower hour of the 1 case 2 are made holes 9.

The gas separator works as follows.

 The carbonated well fluid flows into the separator through the holes: gi 9. In the separator body 2, the fluid receives a rotational, and at the same time, oscillating motion.

In this case, the rotational movement is caused by the curling of the tape 6 in the housing 2 along a helical line, and the oscillatory movement by the liquid flowing around the visors 8. The gas separating from the liquid through the window system 7 made: on the belt 6 rises up. it falls into the vapor pipe A and through the check valve 5 is brought into the annular space. In the gas separator, the acceleration of the rotational motion of the fluid is superimposed on the acceleration of the oscillatory motion by providing a sinusoidal engine of fluid flow, which is achieved at any angle of inclination of the goats other than O (180). The angle of the visors depends on the viscosity and the speed of the fluid.
