在天然裂缝性油藏中有效裂缝间距对水驱和二氧化碳驱设计是很关键的。递减率数据和吸渗数据可结合起来以估算有效裂缝间距 .本文阐述了精心设计的实验室吸渗试验是如何与油田匹配的 ,以及这些简单的观察数据是如何用于估算一个大的天然裂缝性油藏的裂缝间距。裂缝间距也可用水平井岩心单独估算。用递减率 /吸渗间距计算的裂缝间距与从水平井岩心所得的结果极其吻合。
Effective fracture spacing in natural fractured reservoirs is critical for water flooding and carbon dioxide flooding designs. The rate of descent data and the imbibition data can be combined to estimate the effective fracture spacing.This article explains how well-designed laboratory imbibition tests match oil fields and how these simple observations can be used to estimate a large natural fracture Sexual reservoir fracture spacing. Crack spacing can also be estimated separately from horizontal well cores. The fracture spacing calculated from the rate of decline / suction spacing is in good agreement with the results obtained from horizontal well cores.
