| 摘 要： | 本文基于渗流力学原理,综合运用保角变换与等值渗流阻力法推导出扇形板状油藏的产能公式,该公式可以考虑断层夹角、供给边界半径以及井在油藏中的位置等因素对产能的影响。通过与数值方法进行对比,验证了本文产能计算方法的准确性。为指导生产实践,采用本文方法对扇形油藏的产能进行敏感性分析,得到以下结论:产能指数随着供给边界半径的增大而减小,随着井到断层交点距离、断层夹角、井到断层交点连线与断层夹角的增大而增大,断层夹角对产能的影响最大,其次为井到断层交点距离、供给边界半径、井到断层交点连线与断层夹角。

| Abstract: | For its application to production, this work has made sensitivity analysis on the performance of the wells in fan-shaped slab-like reservoirs. This results shows that the productivity index decreases with the radius of supply boundary, increases with the fault included angle, the distance between well and fault intersection, and the angle between the fault and the line linking the well and fault intersection. Of them, the fault included angle has the greatest impact, in turn flowed by the distance between well and fault intersection, the radius of the supply boundary and the angle between the fault and the line linking the well and fault intersection. |
