摘要
随着井网的加密,核三段Ⅸ油组局部区域构造发生变化,因此有必要对低部位油层而高部位为"水层"的储层重新进行认识;根据现有的地质、测井资料,从低阻油层的特征、成因出发,由沉积环境、油气成藏原理入手,结合地质认识成果和测井、录井资料的综合解释方法,准确判断低阻地层的含油气性,在双河油田核三段Ⅸ油组1层发现低阻油藏,提高了油田的储量动用程度并有效缓解了油田产量递减,对核三段Ⅸ油组下步开发有一定的指导意义。
With the well density increasing and the local structural changing in IX Oil Group of Eh3,it was necessary to make re-recognition of the oil-layers that lower part is oil and high part is water.According to the data of existed geology and logging,the characteristics and its causes of low resistance oil-layers,the deposition environment and oil-gas accumulation principles,in combination with the achievements of geological research and the logging data comprehensive interpretation methods,the oil-gas bearing properties of low resistant oil-layers could be accurately judged.The reservoir of low resistant oil-layers was found in IX Oil Group,Shuanghe Oilfield.The oil producing degree increased,and the production decline of oilfield was kept within limits effectively.It provides guidance for the next stage development of IX Oil Group.
