摘要
The Triassic Yanchang Formation Chang-3 reservoir is formed by the gray fine-grained arkose, with bad quality of low porosity and low seepage. The main development space is the pore among grains and solution pore. The pore structure is cotrolled by the diagenesis. According to the lithologic characters, the authors divided the reservoir in this area into 4 types, i.e., 1) good reservoir; 2) fairly good; 3) relatively poor; and 4) non-reservoir.
