有生产潜力的含油气储集层的特征可以用几种特性表示,其中包括孔隙度和含水饱和度.然而,单靠测井得到的孔隙度和含水饱和度作出的结论,还不能区分“好”产层和“接近采完的”产层,也不能直接指出油井的预期产量、油水比和含水量等.但是,从地球物理测井资料可以得出一些补充的数据,从而作出比较完善的储集层分析.这类补充数据包括在完井或重新完井之前预期的油、气、水的比例(油水比,气水比)和预计的含水量.
Features of productive reservoirs can be characterized by several properties, including porosity and water saturation. However, the conclusions of porosity and water saturation based on well logging alone can not distinguish between “ Good ”and“ near-end-of-fill ”production layers, it is not straightforward to point out the well’s expected production, oil-water ratio, water content, etc. However, additional data can be derived from geophysical well logs A more complete reservoir analysis is made, which includes the expected oil, gas and water ratios (oil-to-water ratio, gas-water ratio) and expected water content before completion or re-completion.
