摘　　要：川西海相雷口坡组气藏资源丰富,具有高温、高压、高含硫、埋藏深的特点。面对越来越恶劣的作业工况及复杂的井下条件,针对其测试情况复杂、管柱受力复杂、改造难度大、录取资料难等难点,结合多口井现场案例,通过测试工艺优选、工具改进、管柱优化、降低破裂压力等对策研究,对安全、高效的完成测试,提出合理建议。Gas reservoir resource at Leikoupo unit in Chuanxi is rich and has features of high temperature,high pressure,high-sulfur content and being deeply buried. Facing increasingly harsh operating conditions and complex downhole conditions,according to difficulties of complex well test cases and string force,difficult transformation,hard to acquire data,combined with site case of multi- wells and through researching on countermeasures to optimization of testing process,improvement of tools,optimization of test string,reducing burst pressure,the reasonable suggestions to complete well test safely and efficiently are suggested.
