Abstract

The invention belongs to the field of oil and gas resource exploitation, and relates to a wellhead foam drainage gas production foam automatic detection device which comprises an automatic detection front end, a detection system part and a mechanical structure part. The automatic detection front end comprises a capacitance detection front end and an infrared detection front end, and the detection system takes an MCU as a core controller to realize acquisition, processing and transmission of a detection result; the mechanical structure part comprises a sealing lens, an infrared mounting head, an infrared sensor shell, an optical cavity, a processing system upper shell, a processing system lower shell, a detection front end upper shell, a detection front end lower shell, a detection capacitor, a capacitance sensor shell, a capacitor mounting head and a device shell. According to the device, the wellhead foam can be detected in real time, the accuracy and the real-time performance of detection are improved by adopting the capacitance detection front end and the infrared detection front end, the collected data are analyzed and processed by utilizing the micro-control system, the result is automatically transmitted to the mobile terminal, and the automatic control is completed.

Description

technical field [0001] The invention belongs to the field of exploitation of oil and gas resources, and in particular relates to an automatic detection device for wellhead foam row gas recovery foam. Background technique [0002] Bubble row gas recovery is one of the main means of drainage in the process of gas recovery, and it is widely used in various large fields in my country because of its low cost and good effect. The principle is to inject a foaming agent into the bottom of the liquid-filled gas well. After the bottom-hole liquid is in contact with the foaming agent, a large amount of low-density water-containing foam is generated by the agitation of the bottom-hole natural gas flow. Carried to the ground, so as to achieve the purpose of draining the bottom fluid. However, if defoaming is not complete at some well stations upstream of the gas production pipeline, some single wells do not have defoamer filling equipment, and the separation and filtration are not compl...
