Modular wellhead foam content detection device

Abstract

The invention provides a modular wellhead foam content detection device. The modular wellhead foam content detection device mainly comprises a main body, an outer reducer union, a first locknut, an inner sealing gasket, tempered glass, an outer sealing gasket, an inner reducer union, a second locknut, a laser emitter, a linear silicon photocell, a fixed column body, an explosion-proof joint and aconnecting pipeline, wherein the main body is used for mounting a large reducer union and a connecting pipeline; the large reducer union is used for mounting the inner sealing gasket, the tempered glass, the outer sealing gasket and the small reducer union; and the small reducer union is used for mounting the laser emitter, the linear silicon photocell and the explosion-proof joint. The power supply system and the signal processing system are arranged outside a well site, and the foam detection device is connected with an on-site gas production pipeline to directly measure the foam content inthe pipeline. The structure is designed in a modular mode, installation is easy, rapid replacement of parts of the device can be achieved, the anti-explosion requirement is met, the foam content detection threshold value is high, and precision is high.

Description

Technical field [0001] The present invention belongs to the field of oil and gas mining, and in particular, the present invention relates to a modular wellhead foam content detection device. Background technique [0002] More than half of the gas fields that have been put into development in China have a water gas, after a long time, most of the gas wells enters the primary low-pressure stage, and the foam drainage is one of the main means of drainage and gas, and the application of gas fields in China. very extensive, is an important measure to guarantee stable water wells, the foaming agent is injected from the wellhead to the bottom, and the bottom hole liquid foaming agent contacted later, with agitation gas flow, generating a large number of low density aqueous foam, with the air flow from the bottom Carry it to the ground to smoothly discharge the effusion in the wellbore. However, if the embarrassment in the gas pipeline is not thorough, it will cause a gas pipeline. The f...

Problems solved by technology

This method has serious hysteresis, and the real-time foam content in the pipeline cannot be detected. The detection accuracy is easily disturbed by human factors, and there are many factors that affect the error. It is easy to cause incomplete defoaming and waste manpower and material resources.
