| 摘 要： | 该文考虑到水平井与直井联合面积布井水驱油的非活塞性，运用等值渗流阻力法将渗流区域分成３个阻力区，推导出了联合井网的产量计算通式及油井见水时间公式，并研究了水平井井长和井距对油井见水时间的影响。通过对安塞油田的应用，将所提出的理论计算方法与数值模拟进行比较，理论计算值与数值模拟结果基本一致，最大相差２０％ 。该文推导的公式比较简单，使用方便，能满足工程计算需要，可用于指导油田开发

| Abstract: | Considering the unpiston like displacement in horizontal well vertical well combined areal well pattern, the equivalent percolating resistance method is applied in which percolation region is divided into three resistance regions. The general equation of production in combined well pattern and the equation of water breakthrough time in well are derived. The influence of the length of horizontal section and spacing on water breakthough time is studied. By practical application in Ansai Oilfield and comparing present theoretical calculating method with numerical simulation, theoretical calculating value agrees with numerical simulation result basically. Maximum error is 20%. The equation derived in the paper is simple and convenient to use, meets the requirement for engineering calculation, and can guide oilfield development. |
