摘要
Abstract
The reservoir is characterized by middle-high formation water salinity (50 000 ~ 100 000 mg/L), lower oil viscosity (less than 10 Mpa ? S), higher irreducible water saturation (more than 40%) in Western oilfield of the Taibei sag, Tuha basin. So, there are plentiful oil reservoirs with low resistivity annulus in this area. The resistivity increase index is about 1. 5 in this oil reservoir, it is restrictive to identify such oil reservoir by laterologs. Analyzed are the genetic conditions of low resistivity annulus, the response characteristics of array induction logging in oil reservoir with low resistivity annulus. According to the six resistivity curves of different probing depths provided by array induction logging, and combing with distribution characteristic of low resistivity annulus in this area, proposed are identification methods for oil reservoir with low resistivity annulus. The study enriches evaluation method for low resistivity oil reservoir in the western of Taibei sag, Tuha oilfield.关键词
