A device for putting foam and row sticks and a method for putting in foam and row sticks

Abstract

The invention discloses a foam discharging rod releasing apparatus and a foam discharging rod releasing method, belonging to the field of a gas well draining technology. The foam discharging rod releasing apparatus of the invention comprises a housing which is provided with releasing apertures at the bottom and a foam discharging rod bracket inside. In addition to that, mounting holes of the foam discharging rod are arranged in the foam discharging rod bracket, and all of the mounting holes of the foam discharging rod can match the releasing apertures. A rotary mechanism is arranged on the foam discharging rod bracket and drives the foam discharging rod bracket to rotate in the housing. The foam discharging rod releasing method of the invention includes (1) installing; (2) putting the foam discharging rods in the mounting holes of the foam discharging rod; (3) controlling a solenoid valve, and promoting the foam discharging rod bracket to rotate so that the foam discharging rods fall into the releasing apertures; (4) repeating the step (3) until all the foam discharging rods are released. According to the foam discharging rod releasing apparatus and the foam discharging rod releasing method, the functions of one installing for multiple releasings and the remote control releasing are realized, so as to control the amount of the released foam discharging rods, increase working efficiency and safety, and reduce working strength.

Description

technical field [0001] The present invention relates, in particular, to a gas well drainage technology, in particular to a gas well drainage rod insertion technology. Background technique [0002] The foam drainage device is mainly used for the wellhead of gas production. By putting foam rods 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 to realize the drainage function, so as to prevent the gas in the gas well from dissolving in water. Increase gas production. At present, the method of adding foam row is to install a new valve on the No. 7 valve of the gas tree, close the No. 7 valve, open the new valve, put the foam row stick between the new valve and No. 7 valve, close the new valve, open the No. 7 valve, and the bubble row will fall by its own gravity. This type of method is mainly realized by manually operating the No. 7 valve and the opening and closing of the new valve, and the above proces...

AI Technical Summary

Problems solved by technology

This type of method is mainly realized by manually operating the No. 7 valve and the opening and closing of the new valve, and the above process must be repeated every time it is put in, which is time-consuming and laborious, and this work must be completed on the gas production tree, which poses safety hazards to the operators
