为简化井身结构 ,节约勘探时间和费用 ,塔里木探区一些深井、超深井只下表层套管 ,不下技术套管 ,裸眼井段长达 350 0～ 4 30 0m。鉴于此 ,开发了长裸眼井测试新工艺 ,该工艺采用裸眼支撑跨隔测试技术 ,一开一关工作制度 ,适用于低压地层的直井 ,其测试成功率与泥浆性能、井眼质量有着密切的关系。长裸眼井测试工艺已在塔中 4 0 4、哈得 4和哈得 1
For simplifying hole structure and saving exploration time and cost, people only run surface casing in some deep and extra-deep wells of Tarim exploration area, intermediate casing is usually not run, open hole interval is as long as 3500-4300 m, for this purpose, the long open hole new test technology has been developed. This technology, utilizing bottom support open hole straddle test technique and one opening and one shut-in work system, is applicable to straight wells with low formation pressure, its test success ratio has close relationship with mud property and hole quality. The long. open hole test technology has been successfully used in Tazhong 404,Hade 4 and Hade 1-2 wells. Subject heading
