注产气剖面高压密闭测试技术在塔里木油田的应用

Research and Applications of High Temperature and High Pressure (HTHP) Gasinjetion Profile Hermetical Testing Technology in Talimu Oilfield

对于塔里木牙哈凝析气田的高产气井和高注气量井 ,由于受现有技术的局限 ,用常规注气井剖面测试技术存在一定的困难 ,通过对塔里木牙哈凝析气田 17口井、2 5井次高温高压注产气剖面的测试及资料分析解释 ,开发了一套适合此类井的注产气剖面高温高压密闭测试技术。该测试方法合理 ,剖面正确反映了注产气井各射孔井段的产出注入状况 ,为油田开发提供了科学的第一手动态监测资料。

For high gas rate well and high gasinjection well in Talimuyaha gascondensate reservoir, conventional gasinjection profile testing technology is limited to some degree due to its technical limitation. Through 25 HTHP gasinjecion profile testing in 17 wells and data analyses in Talimuyaha gascondensate field, we developed a new gasinjecion profile hermetical testing technique adaptable to this kind of wells. The testing technique is reasonable, the profile interpretations correctly describe the conditions of output and injection for gasinjection wells′ perforated intervals and provide first hand dynamic data for oilfield development.
