胡状集油田低电阻率油层的研究与应用

在开发过程中，通过有限的地质及测井资料，对低阻油田如何进行判别，是油气田开发中的一个难题。通过对胡状集油田低阻油层系统地研究，分析了低阻油层的成因机理，提出低阻油层的形成是由于其具有独特的储层展布及微观特征；而地层中具有较高含量的束缚水及高矿化度的地层水是低阻油层形成的主要地质条件，确定了以可动水分析法、电阻率增大值法，并参考录井显示的综合解释方法，在胡状集油田胡五块发现了S3中4-6、9-11层系整装低阻油藏，为老区油气滚动勘探和开发提供了重要的指导意义。

Studying and Application the Identifying Method of the Low-Resistvity Reservoir in Huzhuangji Oilfield

It is difficult to judge and develop low resistivity reservoir in term of limited geology information and logging data in the process of development of oilfield. Based on the removed formation water analysis method, the increasing resistivity and geologic log explanation, a comprehensive method of identifying the low resistivity has been introduced in this paper. The reason why the low resistivity reservoir is formed that the special micro characteristic and distribution of Huzhuangji's reservoir. In view of higher irreducible water, the increasing resistivity and higher salinity, there is a low resistivity reservoir of the 4 6, 9 11 zone of the third section of Shahejie of low resistivity reservoir of H5 Block, having an important guidance for rolling exploration and development of matured oilfield.
