扇三角洲储层露头精细研究方法

APPROACH FOR DETAILED STUDY OF RESERVOIR OUTCROP

通过对一个扇三角洲储层露头的详细解剖，探索了一条储层露头精细描述的技术路线，即详细的野外描述、测量和取样；系统的室内分析化验与统计总结和各种地质参数的预测方法研究。同时揭示了扇三角洲内部不同级决的储层非均质性的主要控制因素及其变化规律。在此基础上，通过进一步的研究和探索，建立了该类储集体的原型模型和储层地质知识库，对相同沉积体系的油田地下地质体的识别方法和可靠程度等主要问题作了阐述。

By a fandelta outcrop, a set of techniques and methods of detailed study of reservoir outcrop have been worked out, includ-ing detailed description, measuring and sampling on the outcrop, laboratory experiment, geostatistic analysis and predictionmethods of various geologic parameters. In addition, main controlling factors and space distributions of reservoir heterogeneitiesin different scales of a fandelta have been systematically summarized. As a result, the prototype model and knowledge databaseof reservoir deposited in environment are established so as to be introduced into subsurfacial reservoir analogies for identifying,predicting and evaluating the uncertainty in modeling.
