During the shale gas drainage test stage, the wellhead pressure and temperature are very high, and the produced gas contains a large amount of saturated water, which affects the normal operation of process equipment and gas production pipeline in the test platform. Based on this, on⁃site sampling and test analysis of saturated water were conducted to explore the cause of the effusion in the test platform. Aiming at the reason of liquid accumulation, the scheme of installing partition wall heat exchanger in front of the corrugated plate separator is proposed to reduce the airflow temperature and saturated water content at the inlet of the corrugated plate separator, and Fluent software is used to change the airflow temperature inside the heat exchange tube The situation was simulated. The results show that the average temperature of the air flow in the heat exchange tube can be cooled from 60.34 ℃ at the inlet to 30.00 ℃ at the outlet. The saturated water content can be reduced to 0.731 g/m3 by formula calculation. At the same time, the proposal of installing a hydrophobic hook in the flow channel of the corrugated plate separator is also proposed, and the separation characteristics of the streamlined and hooked corrugated plate separator are analyzed by Fluent software. The results show that the hooked corrugated plate the separation efficiency of droplets can be increased from 28.90% to 76.50%. When the droplet size reaches above 35 μm, the separation efficiency can reach up to 90.00%. The research results have important guiding significance for solving the problem of shale gas test platform liquid accumulation.

Based on the research results in gas field developmment, this paper summarized the development of optimization at domestic and foreign from two aspects: Infilled well deployment, piped network design, pointed out the difficulties and development directions of each part, and provided reference for gas field mining. The analysis points out that there are some difficulties in algorithmic improvement and well pattern density identification in the deployment of infill wells. Further research is needed in the deployment direction of shale gas field infill wells. Model establishment and algorithm improvement are the difficulties in pipe network research, further study of three⁃dimensional terrain relief layout analysis is required.
