| 摘 要： | 在前人研究的基础上,利用保角变换、汇源反映和势叠加原理等渗流理论,对水平井与直井联合布井的五点矩形井网的产能公式进行了理论研究.推导出矩形井网条件下水平井的产量公式,提出了水平井无因次长度的概念,它比井网穿透系数能更好地反映水平井长度和水平井产量的关系,给出了水平井无因次长度与最优井网形状的无因次关系曲线.其结果可用于现场开发方案的设计及产能预测.

| Abstract: | Based on previous studies, this paper made a theoretic research of rectangular Five-spot network deliverability formula of combined horizontal and vertical wells, deduced the deliverability formula of horizontal well under rectangular well network and proposed concept of dimensionless length of horizontal well, which can better reflect the level of horizontal well length and the relationship between output than Penetration coefficient. The paper also gave the dimensionless horizontal well length and the optimal well spacing dimensionless shape curve. The results for all can be used for site development program design and production capacity forecast. |
