Abstract

The invention belongs to the technical field of shale gas exploitation, and in particular relates to an impurity removal system and an impurity removal method for shale gas wells. The impurity removal system for shale gas wells, including shale gas inlet end, shale gas output end and several connecting pipelines, also includes cyclone separator, impurity storage tank 1 and filter separator 1, cyclone separation The filter is connected with the miscellaneous storage cylinder one, the miscellaneous storage cylinder one is connected with the filter separator one, and there is at least one cyclone separator, and the filter separator one is at least one. This system adopts the combination of cyclone separator and filter separator to remove impurities from shale gas. stage separation, and when removing impurities from shale gas, at least one separation can be performed in each stage of impurity removal, so that shale gas can be separated in two stages and multiple times in this system, thereby improving the efficiency of shale gas decluttering effect.

Description

technical field [0001] The invention belongs to the technical field of shale gas exploitation, and in particular relates to an impurity removal system and an impurity removal method for shale gas wells. Background technique [0002] The formation and enrichment of shale gas has its own unique characteristics, and it is often distributed in thick and widely distributed shale source rock formations in the basin. [0003] Shale gas contains a lot of impurities such as sand particles and water. During the exploitation of shale gas, these impurities will corrode pipelines, equipment, instruments, and block valves and pipelines. The existence of these impurities will make valves and pipelines on pipelines Various types of equipment are damaged rapidly, which greatly increases operating costs and even affects normal production. Therefore, when shale gas is exploited, it is usually necessary to remove impurities from shale gas. However, the impurity removal methods currently used ...
