Gas-liquid separation device for single-well booster set

Abstract

The invention discloses a gas-liquid separation device for a single-well booster set. The gas-liquid separation device comprises a tank body, wherein a gas inlet and a gas outlet are formed in two sides of the tank body; a filtering core barrel is arranged in the tank body; the gas inlet is opposite to the side wall of the filtering core barrel; the top end of the filtering core barrel is inclined and is opposite to the gas outlet; a separation filtering net which is bent in the direction of pointing to the top end along the bottom end of the filtering core barrel is arranged at the bottom end of the filtering core barrel. The gas-liquid separation device also comprises a flow blocking plate and a water absorbing plate, wherein the flow blocking plate is opposite to the gas inlet; a gap is formed between the flow blocking plate and the water absorbing plate; liquid moves upwards after direction changing, so that the distance, entering the interior of the filtering core barrel, of the liquid is increased, namely kinetic energy of rest liquid cannot move upwards continuously after the consumption that the kinetic energy is converted into potential energy after direction changing or upward moving, and falls down to the bottom of the tank body directly, so that the gas-liquid separation of mixtures is finally realized, a condition that the residual liquid enters the booster set to cause the halt of the booster set when the residual liquid is conveyed from the gas outlet is avoided, and simultaneously the separation treatment capacity of the booster set is improved.

Description

technical field [0001] The invention relates to a filter, in particular to a gas-liquid separation device for a single well booster unit. Background technique [0002] In the process of oilfield exploitation, abnormal low pressure occurred in some oilfields, which brought certain difficulties to well workover. Some gas wells were exploited at low pressure, and sand was buried in the strata, which could not be cleaned up in time, which reduced the production of gas wells or even stopped production. When downhole operations are carried out without external energy supplementation, the workover fluid pollutes the formation more and more seriously, which makes the drainage period after the action continue to prolong. Therefore, it is necessary to pressurize this type of gas wells no matter during production or liquid drainage. In the prior art, the Gasjack unit can carry out gas-water mixed transmission, that is, the unit has its own separation device, and the separated liquid e...
