Abstract

Disclosed is a gas pretreatment device with an alarm mechanism, which is a gas treatment mechanism with a liquid collector tube and a dry gas collector tube; wherein the gas pretreatment device is connected with an alarm equipment provided with a negative pressure valve structure via a gas transmission pipeline; an inner chamber of a valve chest of the alarm equipment forms a negative pressure chamber which enables a valve plug to slide up and down; a counterbalance is fixed on the upper end of the valve plug. Reasonable allocation of pipeline structure improves heat preservation performance of pipelines; desiccating agent is arranged in the drying treatment section, so that dried gas flows into the pipelines towards a logging room and various moistures are discharged into the liquid collector tube after dipping down; arrangement of the alarm equipment with the negative pressure valve structure facilitates the timely discovery of problems that liquid is pumped into the gas treatment mechanism or the pipelines are frozen or blocked due to other causes, and prompts operators to troubleshoot problems; and the arrangement of a spilled-liquid tube beneath the liquid collector tube enables the automatic discharge of the liquid even though the liquid is in the gas treatment mechanism and stored in the liquid collector tube. The invention is simple in structure, convenient, practical and easier for industrial extension.

Description

Technical field [0001] The invention belongs to an auxiliary device of a gas detection equipment for logging operations in the petroleum exploration industry, and particularly relates to a gas pretreatment device with an alarm mechanism for further dehydration of the gas processed by a degasser before entering a gas analysis program. Background technique [0002] Before the underground well fluid is pumped to the testing instrument room or gas analysis device, because it has just been processed by the degasser, most of the removed gas contains water, which causes the pipeline to freeze and block during the gas-liquid transportation process, which is not only serious Logging operations will also cause damage to related equipment. To this end, the industry has made a lot of efforts. [0003] The conventional gas-liquid separation technology, such as the published Chinese patent 200520109252.4, a crude oil associated gas processing device, is mainly composed of a liquid collecting p...
