碳酸盐岩油气田分布规律

勘探实践表明，碳酸盐岩油气田主要是沿断裂带、不整合面、生物礁发育带、裂缝带及有效烃源岩分布的。我国多旋回海相盆地碳酸盐岩一般经历了我期嘏藏过程。勘探难度很大，但近年来在鄂尔多斯、塔里木以及四川等盆地不断获得新的突破，我国碳酸盐岩在石油工业持续稳定发展中起着十分重要的作用。对碳酸盐岩油气田的勘探必须遵循碳酸盐岩油气田的分布规律、加强碳酸盐岩油气成藏的基础理论研究、开展碳酸盐碉油气勘探技术攻关。

DISTRIBUTION PATTERNS OF OIL-GAS FIELDS IN THE CARBONATE ROCK

Oil-gas fields in the carbonate rocks mainly distribute along fault belts, unconformity interfaces, reef zones, fissure zones and active source rocks. In China, carbonate rocks in the polycyclic marine basins generally experienced multi stages of reservoir formation, and exploration is difficult in these areas. However, there were some successful examples in Tarim, Sichuan and Ordos Basins recently. The carbonate rocks are important exploring areas to ensure Chinese petroleum industry developing steadily. Therefore, oil-gas field exploration in them must abide by the distribution patterns of carbonate oil-gas fields, and the basic theory studies of carbonate reservoir formation as well as the technologies of petroleum exploration in carbonate rocks must be improved.
