摘要
本文首先简述了交会图制作原理及人工用交会图计算孔隙度的方法,接着说明了计算机模拟人工使用交会图计算孔隙度、视颗粒密度以及可能的矿物成分的方法原理。根据所述原理编制的程序处理了若干口井的资料,最后给出了处理实例。
The principle for making crossplot and calculation porosity manually are first introduced briefty. And then use of computer simulation instead of manual calculation of porosity, the apparent grain density and the possible mineral components with crossplot are described. Logging data in several wells have been processed with the programs edited according to the above principle, and final examples are also given.
