Reservoir Geological Features Research Of Gang Dong Development Zone

In this paper, based on structural features of Gang Dong development zone, through the vertical and horizontal sealing characteristics of faults. According to modern principles of sequence stratigraphy, the study area was divided into eight reservoirs, 47 small layer of sand 118 single, six mid-level cycles, established sequence stratigraphic framework. Through to researching microscopic features, pore structure and"four properties"relations of reservoir, heterogeneity, systematically sum up reservoir geological features. After the water injection, reservoir rock porosity , permeability, the micro-heterogeneity and the relative content of clay minerals are increasing and clay content decreases, the reservoir sand is serious. By integrating mathematics and geology subject information, comprehensively evaluate that the study area is about 70% favorable reservoir. Based on study reservoir geological characteristics of before and after injection water, introduce a method of the operability of continental clastic reservoir classification and provide the geological basis for remaining oil field development .
