摘要: 将水平井简化为具有等效井筒半径的直井,考虑了水平井与直井联合布井水驱油的非活塞特性,运用等值渗流阻力法将渗流区划分为3个阻力区,推导出了5种典型的水平井与直井联合井网的油井见水时间计算公式.并研究了水平井长度对不同井网见水时间的影响.引入见水系数对计算公式进行了修正,理论计算值与模拟值基本一致,能够满足油藏工程计算的需要.

关键词: 水平井, 直井, 渗流阻力, 水驱, 井网, 见水时间, 计算公式

Abstract: A horizontal well was simplified into a vertical well with equivalent well bore radius.The seepage flow region was divided into three resistance regions by the equivalent seepage flow resistance method,in consideration of the nonpiston-like displacement in the horizontal-vertical well pattern.The formulas for determining water breakthrough time of five typical combined well patterns were derived.The influence of the length of horizontal well on water breakthrough time was analyzed.The theoretical formula was amended by introducing a correction coefficient.The theoretical calculation value is consistent with the numerical result basically.It is shown that the corrected theoretical formula can meet the requirements of reservoir engineering calculation.

Key words: horizontal well, vertical well, seepage flow resistance, water flooding, well pattern, water breakthrough time, calculation formula
