【摘要】 目的探讨中央拗陷带南缘构造特征与油气勘探的关系。方法对野外调研、地震勘探、钻探及解释结果进行综合分析。结果中央拗陷带南缘自北西向南东依次发育对冲、叠瓦和构造楔 ,其中的石板墩与黑墩构造带中二叠统烃源岩叠置,构造裂缝十分发育,油气成藏条件较为优越。结论中央拗陷带南缘构造带呈现自北西向南东渐趋复杂的构造面貌,且石板墩与黑墩构造带是下一步勘探的最有利区带。更多还原

【Abstract】 Aim To discuss the relationship between the center geotectogence and prospecting for oil and gas. Methods Investigating and studying the field, explaining data of seismic exploration and drilling well and analyzing the whole data. Results There is thrust, imbricate structure and tectonic wedge from north-west to south-east in the south of the center geotectogence. The conditions of pools are best in Shibandun tectonic belt and Heidun te tonic belt because of accumulation of hydrocarbon source rocks and growth of tectonic cracks. Conclusion The tec tonization becomes more and more complex from north-west to south-east in the south of the center geotectogence and Heidun and Shibandun tectonic belts are famous for abundant petroleum resources and very promsing areas for the next prospecting.更多还原
