Abstract

Degassing equipment, a fluid suction structure thereof and a fluid suction head of the fluid suction structure relate to an on-line degassing device for mud sucked in petroleum exploration drillings. A fluid suction head is provided with a fluid suction head body, and a fluid suction pipe portion is arranged on the fluid suction head body and is communicated with a fluid outlet of the fluid suction head body to suck mud; the fluid suction pipe portion is connected with a fluid inlet of the hose pump to feed the mud into the hose pump; and the fluid suction head body is provided with a fluid feed filter end plate for filtering the mud. The degassing equipment is provided with the fluid suction structure, the fluid suction structure is provided with the fluid suction head, and the fluid suction head is provided with a block clearing structure. According to the reasonable matching between the fluid suction structure and a sealing structure of a degasser, purposes of on-line degassing, constant current degassing and quantification degassing are achieved, and further, degassing efficiency is improved.

Description

technical field [0001] The invention belongs to equipment for comprehensive mud logging and gas logging, and relates to a device for on-line degassing of mud proposed in oil exploration and drilling, in particular to a liquid suction structure and a liquid suction head for absorbing mud liquid. Background technique [0002] Degassing equipment is an important part of comprehensive mud logging and gas logging equipment. It shoulders the important task of whether the sample gas can better represent the real gas content of the formation, and directly affects the accuracy of oil and gas field evaluation. [0003] The industry's research on its improvement has never stopped. [0004] In oil exploration and drilling, the mud is raised and the gas is separated online. For this type of degassing equipment, how to make the equipment better achieve "constant flow" and "quantitative" in the degassing operation has always been a constant search in the industry. [0005] The creative id...
