中国石油网消息：8月14日获悉，西南油气田公司大203井标签式滑套分3段压裂施工顺利完成，标志着该公司首次在深层页岩气水平井成功应用该项压裂工艺。

China Oil News: On August 14th, it was learned that the label-type sliding sleeve fracturing operation of Well 203 in the Southwest Oil and Gas Field Company was successfully completed in three stages, marking the company's first successful application of this fracturing technique in deep shale gas horizontal wells.

大203井是典型超深层页岩气水平井。在该井部署实施标签式滑套分段压裂工艺试验，主要目的是探索新型完井方式。为保障试验取得良好成效，西南油气田组织相关专业技术人员提前对标签式滑套结构、性能参数、压裂施工特征等内容进行详细调研，开展了系统的室内评价，不断优化作业参数与应急预案，严格把控工具入井质量，确保各环节顺利衔接和实施。

Well 203 is a typical ultra-deep shale gas horizontal well. In this well, a label-type sliding sleeve staged fracturing technology trial was deployed and implemented. The main purpose was to explore a new well completion method. To ensure the successful outcome of the trial, the Southwest Oil and Gas Field organized relevant professional technicians to conduct detailed research on the structure, performance parameters, and fracturing construction characteristics of the label-type sliding sleeve, carried out systematic in-situ eva luations, continuously optimized operation parameters and emergency plans, strictly controlled the quality of tool entry into the well, and ensured smooth connection and implementation of all links.

作业过程中，技术人员全程驻井把关，加强专业间的协同联动，成功实现单日高效完成3段压裂施工，各项指标达到试验预期。大203井标签式滑套分段压裂工艺现场试验取得成功，验证了该工艺在深层页岩气地质工程中的适应性，丰富了分段压裂作业方式，为西南油气田公司深层页岩气高效开发提供了有力支撑。

During the operation process, the technicians were on-site throughout the process to supervise and ensure the coordination and collaboration among different specialties. They successfully completed 3 sections of fracturing construction in a single day, and all indicators met the expected results of the experiment. The on-site test of the label-type sliding sleeve segmented fracturing technology for well 203 was a success, verifying the adaptability of this technology in deep shale gas geological engineering, enriching the segmented fracturing operation methods, and providing strong support for the efficient development of deep shale gas in the Southwest Oil and Gas Field Company.
