| 摘 要： | 川东北气藏属于高温、高压、高产和含硫海相碳酸盐岩气藏。该气藏气井常规地面测试流程存在地面管汇多处节流和转向，容易形成冰堵、现场操作复杂、含H2S气井测试现场安全性要求高，不易采用人工方式等难点。对气井常规地面测试流程进行了优化：①在测试期间原则上不频繁开关采气树闸阀，第一级节流管汇要临时起到作为井口装置的作用，多台管汇台组合使用；（参采用热交换效率高的EXPRO 35／14型换热器和EXPRO三相分离器；（蓼采用EXPRO地面数据采集系统，可实时采集监测数据，并可以以数字或曲线图的形式显示，按需生成各种报告；④在流程管汇与井口之间设置了ESD紧急关闭阀，可实现瞬时关井。PG101—3井和HB2井的现场应用表明，优化的“70MPa-35MPa”和“105MPa-70MPa”两级节流地面测试流程具有闸门倒换灵活、易于实现有效井控的优点。能适应高压、高产、较长时间下测试的需要，完全能满足川东北地区海相气藏的测试要求。

| Abstract: | The characteristics of Northeast Sichuan marine carbonate gas reservoir are high temperature,high pressure,high production and sulfur bearing.Conventional surface gas well test in this gas reservoir has some difficulties:throttle and steering at several parts of surface manifold,ice-barrier easily,complicated field operation,more safety on sour gas well test and non-artificial way.So,the conventional surface gas well test is optimized.First,during testing,the state of valve of the christmas tree should not ... |
