改造现有工艺回收地面计量天然气

为解决牙哈作业区A区块3口井在见水后含水上升较快、单井产液量增加、现有装置处理能力不足,导致A区块所有生产井不能全部进站的问题,同时为提高最终采收率,需要延长见水时间,见水后控制含水的上升趋势。这就要求掌握含水井的生产动态,而现有装置无法对单井的含水进行计量,塔里木油田公司牙哈作业区A区块建造集中试采装置,文章介绍了改造前后的工艺流程及改造效果。

Recycling Ground Measuring Natural Gas by Transforming Existing Process

All production wells in Block A of Yaha operation area cannot stop because the water content of three wells in block A rise fast after water breakthrough,single-well liquid production increases and the capacity of existing devices is insufficient.To solve the problem and improve the ultimate recovery rate,we need to extend water breakthrough time and control water rising trend after water breakthrough.This requires dynamic control of production wells.However the existing devices can not measure water content of the single well.Block A of Yaha operation area of Tarim Oilfield Company builds concentrated production test devices.This article describes the process and effects before and after reconstruction and transformation.
