摘　　要：针对古龙凹陷向斜区葡萄花油层岩性油藏的勘探潜力、勘探中面临的岩性油藏发育部位预测、油气聚集规律和薄储层预测技术等问题，分析了古龙凹陷具有形成大面积岩性油藏的地质条件。在葡萄花油层3个成藏带认识指导下，开展了以高分辨率层序地层研究为基础的大比例尺沉积微相工业制图、油藏精细解剖研究和薄储层预测技术攻关，进一步深化了向斜区岩性油气分布特征及油气成藏规律认识。通过深化勘探开发一体化评价提交了整装亿吨级储量，从而实现了古龙凹陷岩性油藏勘探的重大突破。在实践中探索形成的岩性油藏区带精细勘探及一体化评价思路和方法，对今后的油气勘探一体化评价工作具有重要的指导意义。According to the exploration potential of lithologic reservoirs of Putaohua formation in synclinal area of Gulong Sag, as well as the problems occurred during the process of exploration such as prediction of positions （ development place ） of lithologie reservoirs, hydrocarbon accumulation rule and thin reservoir prediction, based on the analysis of hydrocarbon source rock evolution and sedimentary distribution characteristics, this paper points out that Gulong Sag possesses the geological conditions of forming massive lithologic reservoir. With the knowledge of 3 hydrocarbon accumulation belts in Putaohua formation, on the basis of high-resolution sequence stratigraphy, key technical researches, including large-scale sedimentary microfacies industrial drawing, reservoir precise phantom and thin reservoir prediction, have been carried out, further deepening the cognition of distribution characteristics and accumulation rules of lithological hydrocarbon reservoir in synclinal area. Through integrated evaluation of exploration and development, over hundreds millions of tons of oil has been submitted, realizing a great breakthrough in the exploration of lithological reservoirs in Gulong Sag. The practical thoughts and approaches on precise explora- tion and integrated evaluation on lithological reservoirs are of great significances to future works.
