The invention relates to the technical field of oil and gas exploration and development, and is a gas drilling formation gas purification and filtration device for mud logging, which includes a filter cartridge, a top cover, an air inlet pipe, an air outlet pipe, a splash baffle and a water vapor baffle, and the upper end of the filter cartridge is fixedly installed There is a matching top cover, and the top cover is provided with an air inlet and an air outlet through up and down at intervals on the left and right sides, and the lower end of the air inlet is fixedly equipped with an air inlet pipe whose lower end is located at the bottom of the filter cartridge. The invention has a reasonable and compact structure and is easy to use. By adding purification liquid into the filter barrel, the formation gas in the gas collection pipe enters the purification liquid through the intake pipe, and the dust in the gas is filtered by the purification liquid, and the purified gas is splashed After being blocked by the baffle and the water vapor baffle, it flows out from the outlet pipe, removes the dust and water vapor carried by the filtered gas, and avoids the damage of the subsequent gas detection equipment caused by the dust. It is safe, labor-saving, simple and efficient.
Description
technical field [0001] The invention relates to the technical field of oil and gas exploration and development, and relates to a gas drilling formation gas purification and filtration device for mud logging. Background technique [0002] At present, when gas is collected by mud logging at the production site of gas drilling, the existing formation gas filter device still contains air bubbles in the filtered gas, and the air bubbles carry water vapor and dust into the subsequent pipeline, which may easily cause dust in the gas to be filtered and polluted. After the liquid is sucked into the gas line, [0003] Increasing the burden of subsequent drying pipes not only increases production costs, but also easily causes inaccurate data detection in formation gas, thus affecting the quality of mud logging and the risk of drilling. Contents of the invention [0004] The present invention provides a gas drilling formation gas purification and filtering device for mud logging, whi...
