川东北海相碳酸盐气藏具有埋藏深、高压、高产、高含硫化氢的特点,针对这种深井及超深井,地层条件恶劣且复杂的试气测试,不仅要求工艺技术安全可靠,确保测试的一次成功,而且也要求工业技术操作性、可行性强,容易掌握与实施。经过几年的摸索与实践,结合目前川东北地区现场试气测试工艺技术,对该地区测试工艺技术进行了总结,形成了一套比较完善、容易掌握与实施的测试工艺技术,为该区的试气测试提供技术保障。
The marine carbonate gas reservoirs in northeastern Sichuan have the characteristics of deep burial, high pressure, high yield and high content of hydrogen sulphide. For such deep well and ultra-deep well, gas test of poor and complicated formation conditions not only requires safe and reliable process technology, Test a success, but also requires the operation of industrial technology, feasibility, easy to grasp and implement. After several years of exploration and practice, combined with the current test gas test process technology in northeastern Sichuan, the test technology in the region was summarized, forming a set of more perfect, easy to grasp and implement the test technology for the area Test gas test to provide technical support.
