摘要: 克拉玛依风城油田2009年开辟重32、重37井区两个超稠油蒸汽辅助重力泄油(SAGD)试验区,通过重32井区2012年SAGD开发区循环预热实践总结,将循环预热细分为4个阶段:井筒预热阶段、均衡提压阶段、稳压循环阶段和微压差泄油阶段,并确定各阶段关键控制节点及判断依据,据此进行实时跟踪优化调控,平均连通程度由34.3%提高至86%,大幅提高了循环预热效果,形成了蒸汽辅助重力泄油循环预热阶段优化控制技术,对以后循环预热现场实践具有指导意义。

Abstract: In 2009, the steam assisted gravity drainage (SAGD) pilot areas of Zhong?32 and Zhong?37 wellblocks were successively estab?lished in Karamay Fengcheng oilfield. Based on the circulating preheating practice summary of SAGD development zone in Wellblock Zhong?32 in 2012, the circulating preheating is subdivided into four stages: wellbore preheating stage, balanced pressure?elevating stage,steady pressure stage and micro?pressure drainage stage, determining the critical nodes and criterions of each stage. Through the real?timetracking optimization and control, the interwell communication degree has improved up to 86% from 34.3%, greatly increasing the effect of the circulating preheating. Such a technology for optimization and control in circulating preheating stage of SAGD will be as a guide for its field practice in the future
