Cluster well development mode is the main mode for the efficient development of unconventional oil and gas reservoirs at home and abroad. Due to the dense well placement and the limited three-dimensional space of the borehole, cluster well trajectory design is faced with: Low wellhead and artificial target matching efficiency and cluster Wells around the barrier design difficulty,cluster Wells orbit design is difficult, to solve the above problems, improve the efficiency of cluster well group orbit design, based on the research, formed the wellhead and targets for efficient matching algorithm, automatic cluster Wells orbit around the barrier design algorithm, developed a cluster well group borehole trajectory automatic design software, The software is applied to complete the trial calculation of automatic trajectory design of 21 cluster well platforms in Sichuan and Chongqing area. The trial calculation results show that: The automatic design software of cluster well trajectory developed in this paper can greatly improve the efficiency of cluster well trajectory design and reduce the design time of cluster well trajectory. It preliminarily realizes the automatic design of cluster well trajectory and effectively promotes the development of cluster well trajectory design toward a higher level of automation
