Application of log-seismic interpretation technology of productivity construction in old areas

After 30 years of oilfield development, the productivity construction center of Jinzhou oilfield has shifted to complex small fault blocks. However, due to small area of fault block and lack of geological data, great difficulties exist in the application of traditional geological research and research methods. In recent years, by using log-seismic interpretation technology, strengthening comprehensive geological study, the structure and distribution of oil and water relations have been renewed and made clear. Aiming at different technologies for different types of reservoirs, the tapping of remaining oil is not only successful in old areas, but the secondary development has been applied in nearly abandoned oilfields. Therefore, the hard-to-recover reserves have been effectively exploited. At the same time, with the application of horizontal well, the successful development of TLC reserves has been realized. Jinzhou oilfield productivity construction is maintained to a certain scale and the development level has been further upgraded.
