6) Cyclic gas injection
循环注气
1.
Yaha 2-3,recovered by cyclic gas injection,is the largest uncompartmentalized gas condensate field discovered in China.
牙哈2-3凝析油气田是目前我国发现的最大整装凝析油气田,采用循环注气开发,由于其凝析油含量高、相态变化复杂,给生产动态的预测带来了很大困难。
2.
The partial pressure maintenance and cyclic gas injection processes were used for development of Yaha 2-3 gas condensate reservoir in Tarim oilfield.
牙哈2-3凝析气田采用循环注气部分保压方式开发,历年的压力监测资料表明压力解释结果异常,采气井压力恢复测试的地层压力普遍高于注气井压降试井的地层压力,给动态分析带来了很大的困难。
3.
Furthermore,integrating effect of driving force,gravation and capillary pressure causes imbibition and diffusion easily, which makes the flowrage character more complex and some abnormal phenomena take place for cyclic gas injection in fractured condensate gas reservoir maitaining pressure.
对于裂缝性凝析气藏来说 ,由于压力下降至露点时析出凝析油 ,相态发生变化 ,加之驱动力、毛管压力、重力综合作用易发生渗吸、扩散现象 ,使得其渗流特征十分复杂 ,循环注气保压开采也会发生反常现象。
