摘要(Abstract):
南堡凹陷2号构造东部是南堡凹陷油气勘探的外扩潜力区,但复杂的地质条件致使油气钻探成功率较低。通过对断裂系统特征、油气运移输导特征和油气保存条件的研究发现,油气的运聚成藏主要受圈闭构造形态、断裂组合样式、油源断裂通源属性、控圈断裂类型、盖层断接厚度、地层砂地比及断层侧向封闭性等因素控制。由于断圈的含油气性受多因素综合控制的影响,因此建立了断圈含油气性综合评价方法,结合已钻富油、较富油及失利断圈的数据,计算得出断圈评价优选标准,并对馆陶组、东一段和东二段的断圈进行了综合评价。
East Structure 2 in Nanpu Sag is the external potential-expanding area of the oil and gas exploration,but the complex geological conditions result in the lower success rate of the petroleum drilling.The studies on the features of petroleum migration transportation and the conditions of the hydrocarbon preservation show that the hydrocarbon accumulation is mainly controlled by the following seven factors;the trap configurations,fault combination patterns,the properties of the faults connected with the oil source rock,trap-controlling fault types,the broken and connected thickness of the cap rocks,sand-formation ratio and the lateral sealing property of the faults.As the oil-bearing property of the fault traps is generally influenced by many factors,the comprehensive evaluating method of the above characteristic is established.Combined with the data of the drilled fault traps enriched or much enriched with oil and in failure,the optimizing standards of the fault-trap evaluation are calculated and furthermore the comprehensive evaluation is engaged for the fault traps in Guantao,East Member 1 and Member 2 Formations.
