摘　　要：川东北地区海相超深碳酸盐岩储层具有高温、高压、含硫等特征,给测试安全性、成功率带来了极大的挑战。为此,在川东北碳酸盐岩含硫气藏测试难点分析的基础上,以提高测试施工的安全性为目的,开展了测试地面控制技术优化研究:通过优选井口装置、优化地面流程,确定出适合于元坝、普光和通南巴地区的井口装置,设计出3套适合于不同工况含硫气井的地面控制流程,最终形成了一套针对性强、适应性好的川东北含硫超深气井测试工艺技术,为川东北含硫气藏测试工作的安全开展提供了安全技术保障。Ultra-deep marine facies carbonatite reservoir is characteristic of high temperature,high pressure and sulfur coated etc. in Sichuan Northeast area,the safety and success ratio of testing face great challenge. On the basis of testing difficulty analysis in carbonatite sour reservoir in Sichuan Northeast area,and in order to improve the safety of testing,the testing ground control technology was optimized. Through wellhead assembly and surface operation regulation optimization,the wellhead assembly suited for Yuanba,Puguang and Tongnanba area was determined and 3 ground control operation regulations suited for sour gas well in different operation condition were designed. Finally,the testing technology suited for ultra-deep sour gas well in Sichuan Northeast area was formed. It provided the safety guarantee for testing sour reservoir in Sichuan Northeast area.
