摘要
隐蔽油气藏的勘探是一切大中型油气田油气勘探开发中晚期所经历的必然阶段。胜利油区孤北低潜山已经取得一定的勘探成果 ,但基本上都是局限于低潜山之上的第三系地层中 ,潜山构造本身还没有取得突破。在勘探程度日益增高的胜利油区 ,类似的勘探目标由于埋藏深、经历了多期构造叠加和破坏 ,研究程度较低 ,但它将是下一步勘探的重点目标和方向。运用大量的实际资料 ,对潜山地层发育及构造特征进行了研究 ,通过构造演化过程的分析 ,论述了反转构造与油气聚集的关系 ,预测总结了油气藏类型和油气分布特征 ,划分了 3个成藏组合 ,指出了勘探潜力和方向。
It is an inevitable process for the mid large oil field to explore the obscure reservoirs in the mid late exploration and development phrase.Of the obscure reservoirs,the buried hill is an important one.In the exploration of Gubei low buried hill,some exploration fruits have been acquired,but it is only confined to the overlapped stratigraphy the tertiary system.There is yet no breakthrough for the buried hill itself virtually.For the high depth and complex tectonic,which result in its lower study,such objects will be the important target and direction by the promoting of the exploration degree in Shengli Oilfield.In this paper,the formation’s growth and the tectonic characteristics of the buried hill are systematically studied on the basis of many data.By the analysis of the process of the tectonic evolution,the relation between the reverse tectonic and hydrocarbon accumulation zone has been demonstrated and the hydrocarbon reservoir types and characteristics of the oil gas accumulation are foretold.In the end,three types of reservoir assemble have been classified and the exploration potential and direction are pointed out in this area.
