港东东营组低阻油层解释方法研究

本文将地质沉积背景与储层岩性结构有机结合，研究低阻油层的成历机理，提出地质条件的特殊性是形成低阻油层的根本原因，弱水动力沉积是低阻油层集中分布的主要地质条件。确定了以地质分析为基础、结合岩性、束缚水分析的综合解释方法，该方法在港东二区东营组应用效果良好。

Interpretation Method for Low Resistivity Reservoir in Dongying Formation in the East of Dagang Oil Field.

Combining the geologic sedimentary background with the reservoir lithologic structure,the origin mechanism of low resistivity reservoir is studied.It is concluded that the speciality of geologic conditions is the basic reasons for forming low resistivity reservoir,and points out the weak hydrodynamic deposition is the major geologic conditions for concentrated distribution of low resistivity reservoir.The intergrate interpretation methods are developed combining with lithologic and irreducible water analysis on the base of geologic analysis.Fairly good application result is obtained in Dongying Formation of the Second Area in the east of Dagang Oil Field.
