塔河底水砂岩油藏夹层对剩余油的影响分析
|
摘要
夹层是影响油水的渗流规律,控制剩余油的形成与分布的重要因素。由于夹层的存在,流体的垂向流动受阻,局部的驱替效果变差,容易形成剩余油富集区。以塔河9区砂岩底水油藏为原型,运用数值模拟方法建立了三维二相黑油模型,研究了不同采液速度、夹层半径、夹层位置对塔河9区砂岩底水油藏剩余油分布的影响。结果表明,剩余油主要分布于夹层下部,采液速度、夹层大小、夹层位置是影响该油藏剩余油分布的重要因素。
Sandwich was an important factor affecting the seepage of oil and water and controlling the formation and distribution of residual oil. Due to the presence of sandwich,the vertical flow of the fluid was blocked,the local displacement effect was worse,easy to form the remaining oil enrichment area. To Tahe 9 area sandstone bottom water reservoir as a prototype,using numerical simulation method,set up three dimensional two phase black oil model,the effects of different flow rate,sandwich radius and sandwich location on the remaining oil distribution in the sandstone bottom reservoir of Tahe 9 were studied. The results show that the remaining oil is mainly distributed in the lower part of the sandwich,the velocity of the liquid,the size of the interlayer,and the sandwich position is an important factor affecting the remaining oil distribution in the reservoir.
