基于多矿物模型分析的最优化测井解释

多矿物模型分析的最优化解释能采用多种测井信息和多种模型来研究和评价复杂油气层。与传统测井解释方法相比,它能将所有的测井信息、误差及某些地区地质经验综合成一个多维信息复合体,运用最优化的数学方法,进行多维寻优处理,来求取地层参数。将该方法应用到乌尔禾低效油田克拉玛依组复杂岩性低渗碎屑岩储层参数解释中,成功解释了该地区一百多口井的测井资料,得到了可靠的地层矿物(岩性)剖面和储层参数。与试油资料、录井资料等对比证实,该方法提供了一种比较有效的地层岩性和物性参数及流体性质的解释方法,效果较好。

THE OPTIMAL LOGG ING EXPLANATION BASE ON MULTIM INERALSMODEL ANALYSIS

Themultimineralsmodel analysis of optimization explanation can study and evaluate complex hydrocarbon reservoir adopting a great of logging formation and many kinds of models.Compared with tradition logging interpretation, it can synthesize multidimensional information complex compound with all logging information, error and some zones geology experiences. Usingoptimalmathematicsmethod and searching the optimal selection of themultidimensional information, which can solve stratum parameter. Applying this method inWu Erhe inefficient oil field Kelamayi group complex lithology and lower permeability clastic rock reservoirbed parameter interpretation, which had explained more than one hundred logging datum successfully, and had gained credibility stratum mineral ( lithology) section and reservoir parameter. Compared with testing for oil data and well logging data, which verified that itwas a newway in explaining the stratum lithology, the physical property parameter and the fluid property, the result is preferable.
