摘要：

With the geologic-seismic integrated survey techniques, such as calibrating fractures and caves and taking seismic attributes on the seismic section; combining seism and log to invert impedance; fracture identification; visual 3-D technology to research the unit of petroleum; semi-quantitatively and quantitatively interpretation of reservoirs etc. , to determine the karst reservoir body and the fracture growing zone, the description and prediction ability is improved obviously for secondary caves and fractures. It is found a series of carbonate oil/gas reservoirs including Well Lungu 100- Well Lungu 12 area; Well Lungu 15 area, Well Lungu 2 area and Well Lungu 13-19 area etc. And high oil/gas production is achieved in Wells Tz 58, 62, and 4-7-38 of Ordovician in central Talimu Basin, and in Well Ym 32 of Cambrian of Yingmaili region in north Talimu Basin. The major breakthrough is made for the carbonate oil/gas exploration of lower Paleozoic in craton of Talimu Basin. As exploration and development go on deeply, the problems appear very seriously such as the high and stable productivity wells are few, the wells produce water soon after production, and the general E&D benefit is low. The accuracy requirement is higher and higher for survey and descriptions of join fracture and cave bodies. So the recent technical key problems to solve are the quantitative prediction of carbonate reservoirs, the identification of karst cave fillers, the quantitative prediction and building model of fractures, and the description of petroleum units.
