一、墨西哥灰岩油气藏的勘探对我们有什么启发(一)海相灰岩发育区,油气勘探大有可为,贵在坚持墨西哥面积196万余平方公里。沉积盆地面积130万平方公里。目前石油年产量4500万吨,平均每人0.8吨,油田产油层主要为侏罗系、白垩系灰岩地层,产量占全国总产量90%以上。且主要集中在滨海平原的侏罗、白垩系台地边缘地区。从本世纪初开始,墨西哥灰岩油气藏的勘探曾经三起三落。一是1901～1938年,在 First, the exploration of the Mexican limestone reservoirs What is the inspiration for us (a) marine limestone development, oil and gas exploration promising, you insist Mexico area of ​​1960000 square kilometers. Sedimentary basin area of ​​1.3 million square kilometers. At present, the annual oil output is 45 million tons, with an average of 0.8 tons per person. The oil-producing reservoirs are mainly Jurassic and Cretaceous limestone formations, accounting for more than 90% of the country’s total output. And mainly concentrated in the coastal plain of the Jurassic, Cretaceous marginal areas. Since the beginning of this century, the exploration of limestone reservoirs in Mexico has been going down and down. First, 1901 ~ 1938, at
