A wellhead foam content detection sensor

Abstract

The invention provides a wellhead foam content detection sensor, which belongs to the field of natural gas exploitation equipment, and consists of a cylinder, a lower sealing gasket, a tempered glass sheet, an upper sealing gasket, inner and outer wire bushings, an infrared emitting head, a silicon photocell, a silicon photocell Seat, battery pack, processing circuit, wireless transmission module, box body, box bottom, box cover, sealing ring, bolts and flanges. The foam content is measured according to the infrared signals of different intensities received by the silicon photocells installed on the inner and outer wire bushings. , the box is welded on the cylinder, the battery pack, the processing circuit, and the wireless transmitter module are respectively installed at the bottom of the box and connected to the silicon photocell and the infrared transmitter to form a circuit with wires, and the foam content detection sensor is connected to the gas production pipeline through a flange. Data is transmitted wirelessly to the display unit. The detection data has the advantages of real-time, high precision and good stability, saving resource costs, improving economic benefits, real-time analysis of the gas production process, and improving production stability.

Description

technical field [0001] The invention relates to a method for measuring foam content in pipelines during wellhead gas production, in particular to a wellhead foam content detection sensor. Background technique [0002] As one of the main means of drainage and gas recovery, foam drainage is widely used in large gas fields in my country. Foaming agent is injected from the wellhead to the bottom of the well. Water-containing foam is carried from the bottom of the well to the surface with the air flow, so as to achieve the purpose of draining the wellbore fluid. However, if the defoaming inside the gas production pipeline is not complete, it will cause secondary foaming of the foam removal agent in the gas collection pipeline and air compressor equipment, which will seriously affect the production and operation of downstream equipment. At present, the foam content detection method of the wellhead gas production pipeline is to rely on manual sampling and detection in the gas-liqui...
