摘要
裂缝性油藏射孔参数优化设计与常规孔隙性砂岩油藏有较大的不同,裂缝的存在使得射孔完井油井的产能评价变得十分复杂。在对裂缝孔隙性油藏射孔参数与油井产能定量关系研究的有限元模拟基础上,对一组水平缝、一组垂直缝、两组垂直缝和三组直交缝情况下射孔参数对油井产能的影响进行了较为详细的讨论和分析,获得了很多有益的结论,研制了裂缝性油藏射孔参数优化设计软件。对裂缝性及裂缝孔隙性油藏的射孔参数优化设计具有重要指导作用,有利于提高油井产能。
The optimization of perforating parameters for improving well performance in naturally fractured reservoirs is quite different from that of conventional sandstone reservoirs. The productivity evaluation of perforated oil well becomes very complicated in the presence of natural fracture in reservoirs. In this paper, the effects of perforating parameters on well productivity for different fracture network configurations, including one set of transverse fracture, one set of vertical fracture, two sets of vertical fractures and three sets of mutual perpendicular fractures, were analyzed and discussed in detail on the basis of mathematical modeling of well productivity by the finite element method. Some useful results have been obtained, and the software.of optimal design for perforating parameters in naturally fractured reservoirs was developed. It is very nutritious to direct the operation of perforating completion in natural fracture reservoirs and thus enhance the well performance.
