摘要:
克拉玛依风城油田2012年开始规模化推广应用蒸汽辅助重力泄油(SAGD)开发技术,为保证循环预热效果、增加水平段连通程度、提高油藏开发效果,对启动阶段进行了注采参数优化研究。根据油藏数值模拟,确定了启动阶段的目标函数及注采参数,对“两目标、三因素、三因子”对比模拟进行敏感性分析,并对注采参数进行了优化。提出了启动阶段高压增温、低汽降耗的调控思路。启动阶段注采参数优化的结果为:预热压力应控制在低于油藏破裂压力0.5~1.0 MPa,水平段温度均匀后1~3 d增压,注汽速度在保证水平段温度均衡的条件下尽量降低。实例应用表明,该优化技术是实用有效的。
Abstract:
The large?scale application of steam assisted gravity drainage (SAGD) technology began in2012in Fengcheng oilfield. In order to ensure the circulation preheat performance, increase the horizontal section’s connecting degree and improve reservoir development efficiency, it is necessary to conduct the research of injection?production parameters optimization at the startup phase. In this paper, the objective function and the injection?production parameters of startup phase were confirmed by reservoir numerical simulation. Sensitivity analysis was done by compared simulation of“two goals and three factors”. The injection?production parameters optimization was then made according to their influencing results. Simulation results show that the high pressure and increasing temperature and the low steam consumption at startup phase should be adopted as follows: the preheat pressure is controlled by0.5~1.0MPa less than reservoir fracture pressure; the pressurization time is1~3days following uniform temperature in horizontal section; the steam injection rate reduces as much as possible in condition of horizontal section temperature equilibrium. The case study indicates that the optimization technology is practical and effective
