Abstract:

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.

Key words: Hzhuangji oilfield, low-resistivity reservoir, increamental value of resistivity, slinity
