Abstract

The invention relates to a motor-driven complementary double-wheel foam bar releasing device applied to the field of natural gas well drainage gas recovery. An upper cover plate is arranged on a shelland connected with the shell through welding, and a charging hole is formed in the center of the upper cover plate; a lower cover plate is installed under the shell and connected with the shell through bolts, and a feeding hole is formed in the center of the lower cover plate; a driving shaft and a driven shaft are installed in the shell, and a driving shifting disc and a driven shifting disc aremeshed with each other and installed on the driving shaft and the driven shaft respectively; and a charging cylinder is arranged on the driving shifting disc and the driven shifting disc, and a driving motor drives the driving shaft to rotate. When the charging cylinder moves to the feeding hole position, a feeding motor drives a pushing rod to push foam bars to fall into a shaft. Compared with the prior art, the device has the advantages that the transmission is simple, the components are few, and the overall equipment is arranged in a centering manner; after one-time installation, remote multiple delivery can be automatically realized through the driving of the motors, the operation is safe and reliable, the labor intensity of operators is reduced, and the working efficiency is improved.

Description

technical field

[0001] The invention relates to the field of drainage and gas recovery of natural gas wells, in particular to a motor-driven complementary double-wheel foam row rod feeding device. Background technique

[0002] In the process of natural gas exploitation, due to the gradual decrease of gas reservoir storage pressure and natural gas flow velocity, the formation water or condensate of the gas well cannot be carried out of the wellbore by the natural gas flow, resulting in wellbore fluid accumulation, seriously affecting the normal production of the gas well, and even Water flooding of gas wells, rapid and effective removal of fluid accumulation in the wellbore of gas wells has become one of the main tasks of gas production workers. The foam row rod feeding device is mainly used for the wellhead of gas production. By putting the foam row rod into the gas well, it dissolves and foams with the water in the gas well, and the natural gas is taken out of the gas well ...
