【Abstract】 A series of exploration techniques for carbonate buried-hill reservoirs applied in Shengli Oil Field were introduced. The application of joint inversion of gravity and seismic data, 3D pre-stack depth migration and 3D seismic jointing processing techniques gave high-quality data and improved the precisions of target selection and description of traps. The techniques of reservoir analysis, well bore description and the cross-hole reservoir lateral prediction could enhance the accuracy of well deployment. The application of pattern recognition and simulation technique for oil and gas transportation and accumulation provided a direct or indirect evidence for exploration decision-making oil and gas. A lot of drilling techniques, acid stimulation and compressive fracturing techniques effectively protected and stimulated the performance of reservoir. The use of these techniques improved the exploration level in carbonate buried-hill of Jiyang Depression.更多还原
