摘要
针对油田现场对底水油藏水平垂向位置优化的重要性尚未得到统一认识的现状,从水平井垂向位置对底水油藏临界产量和见水时间的影响入手,推导出了临界产量和见水时间与水平井垂向位置的关系曲线,给出了底水油藏水平井临界产量和见水时间的计算公式。在综合考虑临界产量和见水时间的基础上,得到了底水油藏水平井最优垂向位置的范围,其结果对底水油藏水平井的油藏工程设计具有一定的指导意义。
Based on that facts that no agreement has been achieved on the importance of optimum vertical location of horizontal wellsin reservoirs with bottom water, being started with the impacts of vertical location on the critical production rate and water breakthrough time in bottom water reservoir, the relation between and vertical location of horizontal wells was derived, the equation to calculate the reservoir with bottom water was provided. Comprehensively considering critical production rate and water breakthrough time, an optimum vertical location range was obtained and the results can somehow provide the guidance for design of horizontal wells in reservoirs with bottom water.
