| Abstract: | Through observed outcrop sections,described cores from formations,analyzed test reports,and many other data,the reservoir rock characteristics,the main types and characteristics of diagenesis,diagenetic stage and evolution succession of middle-deep strata in Ganchaigou-Xianshuiquan region of Qaidam Basin in Qinghai Oilfield were studied systematically,and the influence and discipline of diagenesis on the reservoir properties were revealed clearly.The result shows:In this region,the reservoir mainly consiste... |
