圣地来哥 (Sandirego)油田是 6 0年代投入开发的老油田。该文针对油田具体地质特点 ,建立了“凹陷—斜坡关联体”含油气系统概念模型。通过大量钻井、地质、地震、测井、油藏工程资料的分析 ,在各含油气子系统 ,尤其是圈闭和储集子系统评价等方面取得了突破性的认识。文中指出 ,圣地来哥斜坡北缘 1号断层下降盘逆牵引滚动背斜带和西部低部位断块群 ,是两个极有前景和潜力的扩边滚动勘探新目标 The Sandirego field was an old oil field that was put into operation in the 1960s. According to the specific geologic characteristics of the oilfield, a conceptual model of “sag-slope associated body” petroleum system is established. Through a great deal of drilling, geology, seismic, well logging and reservoir engineering data analysis, breakthroughs have been made in various oil and gas subsystems, especially trapping and reservoir evaluation. It is pointed out that the reverse traction-rolling anomaly belt on the north margin of the Sao-Gelao slope and the fault block group in the western part of the lower part of the fault are two promising new targets for expanding-edge rolling exploration
