申时新等：综合测井和地震资料描述岩性的蒙特卡洛法，测井技术，１９９６（４）２０，２６８～２７０。考虑了测井纵向分辨率高但横向分辨率低的特点，利用地震资料作为测井岩性外推过程的约束，对地下岩性进行描述。利用地震资料时，该方法考虑了地震信息的不确定性和模糊性，将地下岩性分布看作随机场的一个特定实现，利用ＭｏｎｔｅＣａｒｌｏ法对井孔以外的岩性进行横向模拟，能够给出储层岩性多种可能的图象。
Shen et al.: Comprehensive Log and Seismic Data to Describe Lithology by Monte Carlo Methods, Logging Techniques, 1996 (4) 20, 268-270. Considering the features of high vertical resolution but low horizontal resolution, seismic logging is used as a constraint of logging lithology extrapolation to describe the underground lithology. When using seismic data, the method takes into account the uncertainty and fuzziness of seismic information, considers the underground lithology distribution as a specific implementation of random field, and uses Monte Carlo method to simulate lateral lithology other than borehole to give Various possible images of reservoir lithology.
