| 摘 要： | 随着时间的推移,早期对辽河西部凹陷牛心坨地区成藏条件的认识已经无法满足现时开发需要,有必要对其进行重新分析。通过对该区烃源岩、储层、盖层及油气运移等要素的研究,对该区成藏特征有了新的认识。研究表明:牛心坨地区具备沙4和中生界2套烃源岩供油条件;储层具有"纵向成层,横向分带"性,混合岩类储层为优质储层;沙4段高升亚段暗色泥岩即是主要烃源岩,也是区域盖层;沙4段和中生界烃源岩紧邻太古界潜山,潜山内幕具备近源成藏条件。研究认为牛心坨地区太古界变质岩潜山深层具备很大勘探潜力。

| Abstract: | The early knowledge about hydrocarbon accumulation conditions in the Niuxintuo area in the Western Depression of the Liaohe Oilfield has been outdated and it is necessary to be reanalyzed.New understandings have been obtained through investigation on key elements such as source rock,reservoir,cap rock,and hydrocarbon migration.The study indicates that: the Niuxintuo area has two source rocks,which are Es4 and Mesozoic rocks;the reservoirs are vertically laminar and laterally zonal,with mictosite reservoirs ... |
