通过对东濮凹陷胡状集油田一台阶深层油气藏形成条件的分析探讨,总结出在进行深层油气勘探时,不但应重视勘探地区深层超压带的存在、预测及其与深层油气藏形成的关系,而且要深入研究勘探地区的地温史、生烃史、沉积构造发育史,油气多次运移特征、深层储、盖层发育特征(包括裂缝发育特征) 及深层流体特征等多种因素。

Based on analysis and researches on deep reservoir forming conditions in the first step of Huzhuangji Oilfield ,it is realized that not only we have to pay attention to the existence of the deep overpressure belts , but also the prediction of its relations with forming of deep hydrocarbon reservoirs. We have to make a thorough study on the history of geo-temperature , hydrocarbon generation and sedimentary structure development as well as the characteristics of multiple hydrocarbon migration , deep reservoir and cap rock development ( including fissure development ) and fluids in deep reservoirs. Such that we can achieve a better effect in the exploration of the deep hydrocarcarbon reservoirs. Several history cases are provided in this paper. The views and techniques presented in this paper could be instructive to the deep reservoir exploration in other oilfields.
