摘要:
渤海辽东湾区域X油田构造陡,地层倾角约25°,地层厚,原油为轻质油,水油密度差大,注水开发中注入水受重力影响非常明显。基于渗流理论,推导了考虑重力的一维两相活塞式驱替油水界面移动到任意点处的时间,得到构造高部位和低部位油井同时见水的注采井距。通过贝克莱方程和数值模拟,研究了针对该油田的最佳注采井距,对陡构造轻质油油藏注采井距的优化具有指导意义。
Abstract:
X Oilfield in Bohai Bay area has characteristics of steep structure, a dip angle of about 25°, thick oil-pay, light oil, big density difference between oil and water. So injection water is obviously affected by gravity during waterflooding. Based on the theory of seepage, it was deduced the time of oil-water interface of one-dimensional two-phase piston-like displacement considering the gravity to any point. And the injection-production well spacing was obtained, that oil wells located in high and low positions of the structure have the same time of water breakthrough. According to Berkeley equations and numerical simulation, the injection-production well spacing for the oilfield was optimized. This provides a guide for optimization of the injection-production well spacing of light-oil reservoir with steep structure.
