水平井井网整体开发产能研究

随着水平井技术的成熟与发展,以单水平井开发为主的开发模式已转化为以水平井井组整体开发为主,因此对水平井井组产能的准确分析与预测至关重要。从无限大地层内单一水平井、直井联合井网的解析产能出发,经过理论分析,得到了多个水平井、直井联合井网整体开发油藏的产能预测方法,并通过电解模型试验进行了验证与修正。修正后,半经验、半解析解的预测结果与试验结果拟合得非常好。

Productivity Study of Horizontal Wells Pattem

With the development of horizontal well technology, the fashion of exploiting pattern has been gradually changed to horizontal well pattern from single horizontal well, so it's very important to forecast the product condition of the horizontal well pattern exactly. In this paper, the analytical productivity of single horizontal well network in the boundless oil field is discussed, and with theory analyzing, the method is found to forecast productivity of the horizontal well network union. By comparing with the experimental productivity, the method has been also modified and the precision of the new semi-analytical and semi-experimental method is much better than before.
