针对茨榆坨斜坡带构造、沉积背景下岩性油气藏分布的控制作用，运用层序地层学理论，建立该区的层序地层格架；应用“地震储层微属性差异烃类检测新技术”与地震储层预测技术相结合，预测了该区油气聚集的有利区带。并结合储层沉积岩石学和成岩作用理论等技术和方法，加强多学科的有机配合，建立适用于本地区地质特征的配套勘探技术，确立该区岩性油气藏的分布特征，在岩性油气藏滚动勘探中取得了突破。

In view of the Ciyutuo slope structure features and the controlling effects of lithological hydrocarbon reservoir distribution
under the sedimentary background, the regional sequence framework is established based on the sequence stratigraphy theory. In
the study, the favorable oil and gas accumulation belt is predicted by using the reservoir forecast technology and hydrocarbon
detection by seismic micro-attribute difference. In addition, the associated exploration technology suitable to the area has been
developed combined with reservoir sedimentary lithology and integrated the seismic reservoir prediction method with multi-disciplinary team work. As a result, the distribution features of lithological hydrocarbon reservoir are defined, which is a great
breakthrough in the progressive exploration of lithological reservoirs.
