【摘要】 本文以霸县凹陷深潜山为研究目标,借助地震、地质、测井、录井等资料,并结合地球化学研究方法,分析了潜山油气成藏的基本要素、恢复了油气成藏的基本过程,探讨了烃源岩、储集层、盖层、运移、圈闭、保存等各要素和各阶段的特点及匹配关系,在此基础上对霸县凹陷潜山油气成藏条件进行了综合评价,剖析了典型的苏桥、龙虎庄潜山油气藏,预测出霸县凹陷潜山有利的勘探区带。霸县凹陷发育推进式和平衡式的基底结构,发育有诸多与主断层近乎平行的反向正断层;凹陷内油气源来自于古近系深层的烃源岩,围绕着霸县洼槽呈环带状分布。区内发育多套储盖组合,寒武系的府君山组、奥陶系峰峰组和马家沟组、蓟县系雾迷山组都是较好的储集层。霸县凹陷发育的有效圈闭均分布在了主要的构造带上,加之由不整合、大断层及渗透性储集层组成的庞大的运移网络,使得深层油气源不断的向潜山储层运移。按照圈闭落实有效、储集层良好、沟通油气源条件较好及油气聚集有利区带的评价原则,预测出霸县二台阶、兴隆宫、史各庄潜山带为有利勘探区域。更多还原

【Abstract】 In this paper studied buried hill of Baxian depression. Used seismic, geology, well logging and other data, combined with the geochemical studies method. This paper analyzed the buried hill hydrocarbon accumulation and reinstated the basic elements of oil and gas accumulation, explored the basic process of hydrocarbon source rocks, reservoir, cap rock, migration, traps, preservation and so on various factors, analyzed the characteristics of each stage and matching relation. Based on the above work, complement buried hill hydrocarbon accumulation conditions of comprehensive evaluation, analyzed LongHuZhuang and SuQiao buried hill hydrocarbon accumulation. Because of those, completed favorable prediction of exploration zones.Baxian depression development promoting type peace line-like basement structure, development has approximately parallel with the main fault of the reverse is fault, sag of oil and gas source from the inside of the ancient near deep hydrocarbon source rocks, within Baxian subsags around a ring belt distribution. Zone development reservoir-cap combination of the mansion, Cambrian JunShan group, Ordovician fengfeng group and majiagou group, jixian department fog fan mountain is a good group of reservoir. The effective trap Baxian depression development are distributed in the main structure bring, plus large faults by unconformity, reservoir and permeability of the migration network, making huge oil-gas source constantly to deep buried reservoir migration. According to trap implement effective and reservoir good, communication oil-gas source conditions are good and accumulation of the principle of evaluation, favoratble zones Baxian two steps, predicted the brisk palace, ShiGeZhuang buried hill band for the history for exploration areas.更多还原
