Abstract

The invention relates to a gas pretreatment device for logging and the alarm controller, which is the assistant device of gas measuring equipment in logging work of oil exploration industry, comprising gas treatment mechanism with fluid collection tube and dried air collection tube. Said gas treatment mechanism is connected with the alarming controller with negative pressure valve by gas transmission line. The reasonable allocation of pipeline structure improves the insulation effect of pipeline. Desiccant is set in drying treatment zone so that air after drying flows into pipeline in loggingroom and various moisture drops down and is discharged form fluid collection pipe. The configuration of alarm controller can realize anti-explosion and alarming. The configuration of overflow pipe atthe lower of fluid collection pipe makes the fluid collected in collection pipe drain automatically, when the fluid enters into gas treatment mechanism. The invention is provided with simple structure, convenience and practical and ease popularization.

Description

technical field [0001] The invention belongs to an auxiliary device for gas detection equipment used in mud logging operations in the oil exploration industry, and in particular relates to a gas pretreatment device for further dehydration before entering a gas analysis program after being processed by a degasser, and an alarm control device thereof. Background technique [0002] Before the underground well fluid is pumped to the detection instrument room or the gas analysis device, since it has just been treated by the degasser, most of the degassed gas contains water, so that the pipeline often freezes and blocks during the gas-liquid transportation process, which not only seriously affects If the mud logging operation is stopped, it will also cause damage to related equipment. The industry has made a lot of efforts for this. [0003] The known gas-liquid separation technology, such as the published Chinese patent 200520109252.4, is a crude oil associated gas treatment dev...
