摘要

以东濮凹陷胡状集地区胡五块沙三中地层为研究目的层段,在前人研究的基础上,从岩心实验测量入手,应用地球物理测井和石油地质学的基础理论,通过对研究区内目的层段沉积环境、水流作用过程、骨架矿物和粘土矿物类型、泥质含量等方面的深入分析,揭示了区内低阻油层的成因。高矿化度、中高孔隙度和高束缚水饱和度是造成研究区油层低电阻率的主要因素,粘土矿物的含量和分布形式、导电矿物的存在是其次要因素。

Abstract

Take the Es₃ stratum with study objective interval in

Huzhuangji area in Dongpu depression , based on the former

research ,according to the result of core survey in lab ,apply the

basic theory of geophysical well logging and petroleum geology ,

by deeply analyzing the sedimentary environment and current

effect and the styles of framework mineral and clay mineral and

mud content , reveals the cause of formation of low resistivity

reservoir . In there has found the major factors that result in low

resistivity reservoir are high salinity and middle to high porosity

and high irreducible water saturation , the minor factors are

content and distribution of the clay mineral , the existence of

conducting mineral is also a minor factor.
