川东北海相气藏埋藏深、温度压力高、普遍含硫、平面及纵向产量变化大，测试工艺复杂，面临井下工具受限、井下事故复杂、井控及环境污染风险大等难题。在川东北高含硫气井测试实践与经验基础上，形成了高压高产含硫气井测试技术。形成了三类六套APR射孔—酸压—测试联作短期测试管柱；管柱力学分析、多级压力控制、国产抗硫及复合地面流程等测试配套工艺满足各类测试要求；以压井、防喷、防漏为主的测试应急方案及措施确保了作业安全。该技术在YB1-侧1，YB12，HB1-1D等井中成功应用，为该类气田勘探开发的顺利进行提供了技术支撑。

There were many characters in marine gas reservoir of the northeast Sichuan, such as deeply buried, high-pressure and high temperature, generally sulfur-containing, production changes significantly in flat and vertical. Which lead to the complicated testing technologies, containing the limited tools, complicated downhole accidents, well-control and the risks of the environment. Based on large numbers of laboratory practices and experiences, well testing technology in high-pressure and high-production sulfur-containing gas reservoir were put forward, including three classes of APR perforating and acid fracturing combined well testing string, string mechanical analysis, multi-pressure control, domestic sulfur resistance and compound surface flow process, which could meet all kinds of testing technology requirements. Emergency schemes and strategies ensure the operation safety, including well killing, blowout prevention and leak proof. These technologies were successfully applied in YB1-C1,YB12 , HB11D and other HPHT sulfur-containing wells, which provided technical support for these gas field exploration.
