Description

The known devices (ladders) for separating gas from oil, acting on a gravitational principle, are heavy, take up a lot of space, and are not efficient enough. In order to improve their operation, several ladders are installed in series, each of which has its own measuring and regulating automatic equipment to maintain the level and pressure constant. the ladder. This leads to large investments in the creation of fisheries and difficulties in exploitation.

The proposed hydrocyclone separator has high productivity, relatively small size and weight, as well as a high degree of gas purification from liquid. This is ensured by the fact that on the side surface of the horizontal apparatus, the upper part of which is a gas separator, one or two hydrodicones with screw screws are installed, having windows on the second and third turns, and a groove on the last turn.

FIG. 1 shows a structural diagram of a medium and low pressure hydrocyclone separator; in fig. 2 - high pressure hydrocyclone separator.

The medium and low pressure hydrocyclone separator consists of a single-screw helical cyclone body 1, a process tank 2, a screw screw 3, a gas sampling pipe 4 with windows 5 for sampling a part of gas, a distribution grid 6, a tangential gas injection 7, a gas separator 8 a gas distribution grid 9, an inclined flange 10, a base 11 of a separator with an oil outlet, a discharge gas pipe 12. At the last turn of the screw auger, a groove 13 is formed for transferring oil into the process tank.

The oil and gas mixture comes from the wells through a tangential injection, which, together with the auger, gives the mixture a rotational two. Fluid, having a larger specific gravity than gas, is thrown back by centrifugal force to the body, and in the center remains the volume,

valuable gas that comes out of the screw hydro cyclone through

in the gas pipe. Fluid making a few turns on

through the groove on its last turn enters through the pipe 14 into the technical container. The groove is positioned so that the oil is drained over

her pipe surface; it promotes further separation

Oil, the entrance to the process tank, spreads thin

 along an inclined shelf where final separation takes place

after which the last, passed through two systems of gratings and a bump in,

It comes from small fluid particles entrained in gas.

The high pressure irocyclone separator consists of two

single-flow hydrocycloi and two horizontal technological tanks installed one above the other. Single screw hydrocyclones and upper technological capacity are similar.

in a hydrocyclone separator of medium and low pressure.

1ft from hydrocyclones through the gap in the bottom

1 technological capacity, flows on a cylindrical baffle 5 in the lower technological capacity 16, where the end, and the separation of gas.

Subject invention

an irocyclone separator for separating gas from oil, characterized in that, in order to ensure a high degree of separation from oil, on the side surface of the horizontal apparatus, the first part of which is a gas separator, installs; or two hydrocyclones with screw screws having DM on and the third round of the window, and the last round of the groove.
