摘　　要：一种能够充分利用测井资料的测井解释处理软件———多矿物模型 ,通过将每种测井资料与地层中的各种矿物及其含量建立函数关系 ,获取地层中的各种矿物含量 ,并以此准确划分地层岩性、计算储层参数 ,大大提高了测井解释处理的精确度 ;还可以利用现有的测井资料有效合成一段缺失的测井曲线 ,使得因故缺失某种测井资料的井段也能够得到全面的解释处理。A new well_logging interpretation software—multi_mineral model is developed with well_logging data. This software can obtain the mineral_contents of well formation by setting up the relationship functions between every well_logging data and the mineral_contents of formation, and consequently the formation lithologies can be determined, the reservoir parameters can be computed on that, so the well_logging interpretation accuracy is risen greatly. A section of artificial logging curve can also be compiled by using other obtained logging data, so a full logging interpretation process can be getting on as well as in a section with a logging curve lost. Practical uses bear out the advantages of the software. This paper introduces mainly the interpretation and data process methods of determining the formation lithologies, compiling artificial logging curves and computing reservoir parameters with the multi_mineral model.
