摘要
为充分认识大芦湖油田的油气成藏规律,提高大芦湖油田的勘探开发效果,针对该油田沙三段岩性油藏樊107块和樊162块在开发中存在的油层产能差别大、油层有效厚度下限标准不一致及油水矛盾等问题,通过沉积物源分析、古地貌恢复研究及储层岩性、物性特征、结构及构造特征、测井相特征等沉积特征的研究,建立了两块的滑塌浊积扇沉积模式。该模式合理解释了樊107块构造高部位为水层而相对低部位为油层的成藏机理,同时对大芦湖油田岩性油藏的勘探开发具有重要的指导意义。
In order to fully understand the rule of hydrocarbon accumulation in Daluhu oilfield and improve the effect of exploration and development of Daluhu oilfield,according to the problems during development of the lithologic reservoir in the 3 rd member of Shahejie formation of Fan107 block and Fan162 block in this oilfield,such as the productivity differences among oil layers,inconsistence of the minimum standards of reservoir effective thickness,and oil and water conflict,through sediment source analysis,paleogeomorphology restoration research and the study of the reservoir sedimentary characteristics such as reservoir lithology,physical property,structure,tectonic characteristics,and log facies features,the sedimentary model of the slumping turbidite fans in these two blocks were established.This paper explains the reservoir forming mechanism of the structural reservoir with high water layer and relatively low oil layer in Fan107 block.The model has important guiding significance for the exploration and development of lithologic reservoirs in Daluhu oilfield.
