Automatic foam discharging ball filling device and method

Abstract

The invention discloses an automatic foam scrubbing ball filling device which comprises a storage mechanism, a conveying mechanism and a waste gas treatment device. The storage mechanism comprises a stock bin and a storage chamber which are communicated through a feeding pipeline, and the storage chamber is located above the stock bin. The conveying mechanism comprises a dewatering chamber communicated with the storage chamber and an air filtering chamber communicated with the dewatering chamber; the input end of the gas filtering chamber is communicated with the gas production tree; the gas filtering chamber is divided into two parts through a filtering unit arranged in the gas filtering chamber, the part below the gas filtering unit is communicated with a waste gas treater for absorbing waste gas in natural gas through a first exhaust pipeline, and the part above the gas filtering unit is communicated with a foam discharging ball collecting chamber through a discharging pipeline; the material storage chamber, the dehydration chamber and the air filtering chamber are respectively communicated with a centralized positive pressure air supply device through positive pressure pipelines; and the storage chamber is communicated with a vacuum generator through a vacuum pipeline. According to the device, automatic feeding and discharging of foam discharging balls are conducted through the air pressure difference, waste gas can be separated and treated at the same time, and the natural gas extraction efficiency and the extraction work stability can be improved.

Description

technical field [0001] The invention belongs to the technical field of natural gas exploitation, relates to the technology of filling bubble volleyballs at the wellhead of natural gas, and in particular relates to a device and method capable of realizing automatic filling of bubble volleyballs. Background technique [0002] In the middle and late stages of natural gas well exploitation, bottom hole liquid will accumulate due to insufficient liquid-carrying capacity, resulting in water flooding and shutdown of gas wells. Filling with solid bubble volleyball is an effective means to remove the gas well accumulation and maintain the stable production of the gas well. The traditional manual identification of effusion and artificial bubble discharge has the following problems: untimely early warning of effusion, high labor intensity, inability to maintain stable production of gas wells with the frequency of artificial bubble discharge, frequent use of vehicles and manual operatio...

AI Technical Summary

Problems solved by technology

The structure of the above-mentioned bubble volleyball automatic filling device is very complicated, not only difficult to maintain, but also prone to unpredictable accidents

Moreover, the above-mentioned automatic filling device cannot realize automatic feeding, and it is difficult to meet the needs in the field

At the same time, the above-mentioned device does not consider how to treat the exhaust gas, which does not meet the needs of today's green industry development
