Abstract

The invention provides an earth gas collection screw auger which belongs to the drilling tool technical field. In order to solve the problems of complex operation, inconvenient maintenance, poor strength and limited collection depth lying in the prior earth gas collection screw auger, the invention proposes the earth gas collection screw auger comprising a taper bit body, a close cover screw rod, a drill rod and a handle, wherein the taper bit body is in screwed connection with the taper end of the close cover screw rod, the other end of the close cover screw rod is connected with the drill rod, the drill is then connected with the handle, a gas collection chamber is arranged inside the taper bit, vent holes communicated with the gas collection chamber are arranged on the bit, a filter element and a gasket are arranged inside the gas collection chamber, a gas taking long slim pipe contained in the filter element passes through the center of the gasket, and a holding-down bolt is used to compress the gasket to separate the gas collection chamber from the outer atmosphere. The gas taking long slim pipe is connected with a gas taking device after passing through the close cover screw rod, the drill rod and the handle in turn. The earth gas collection screw auger is a manual earth gas sampling device integrating gas picking and collection with convenient carrying, simple assembly, convenient maintenance, high strength, convenient operation, simplicity as well as reliability.

Description

technical field

[0001] The present invention relates to a drilling tool, more particularly, the present invention relates to a drilling tool for collecting gas in soil. Background technique

[0002] The soil free hydrocarbon method is a gaseous hydrocarbon method that uses a gas collector to collect the gas in the soil pores, analyzes the hydrocarbon components in the gas, and conducts oil and gas chemical exploration. The use of soil free hydrocarbons in oil and gas exploration began in the 1930s. Due to the limitations of sampling and analysis and testing techniques, this method has not been greatly developed in my country.

[0003] The collection methods of soil free hydrocarbons are divided into active method and passive method. The passive method does not require any air extraction device, but the trap device must be placed on the sampling point for several days. The active method is divided into the active extraction method and the active concentration method. The act...
