摘　　要：本文从储层岩性、物性、含油性、电性特征四个方面系统地总结了姬塬地区长4＋5、长6低渗透储集层特点．指出了姬塬地区长4＋5、长6低渗透储集层的特殊性。Through the analysis of characteristics of sedimentary, reservoir, physical properties and well logging etc., the profitable exploring layer are discussed in the paper. The profitable layer must have a good porosity and relative good permeability. All these are determined by the depositional environment.

关 键 词：长4+5 长6油层组 低渗透储集层 特征 姬塬地区
