川东北高温、高压、高含硫气井测试地面控制应用技术研究

Technology Study on Surface Controlling of Well Test in Gas Wells with High Temperature,High Pressure and High Sulfur Content in North-East of Sichuan

为消除或降低四川盆地川东北北海相碳酸岩含气区域气井深井试气因高温、高压、高含硫所带来的爆炸、泄漏、中毒等危险,对国内外先进测试设备进行改进研究,形成了一套独具特色的川东北测试控制工艺技术,满足了川东北地区气井测试施工要求,正确处理有毒有害气体,有序排放液体废物。

In order to avoid or reduce dangers,such as explosion,leakage,poisoning and so on,which is brought from gas well test in deep well with high temperature,high pressure and high sulfur content in the gas region with marine facies carbonate rock of Beihai of north-east of Sichuan basin,by comprehensive application and development research on advanced testing equipment at home and abroad,one set of special test controlling technology in north-east of Sichuan is formed,which meets the needs of gas well testing in this region,and can correctly dispose of noxious and harmful gas,and orderly discharge waste fluid.
