环江地区长8储层属于低孔、低渗型储层,影响产能的因素很多,测井资料能反映一定的地下信息,这是直接与储层产能有着必然的联系。如果忽略其他的影响,这些地质参数是可以说明一定问题的。根据前人经验,影响储层产能的主要因素是:孔隙度Φ、渗透率K、有效厚度H、含油饱和度So等参数。结合试油资料和储层特征的处理结果,得到该地区长8层油水识别标准。再根据各参数与试油日产量关系图,划分储层等级。单纯的利用一种参数去预测储层产能效果是不确切的,针对环江地区油层特点,利用有效厚度×含油饱和度乘积法预测与实际的的生产状况较为符合。
The Chang 8 reservoir in the Huanjiang area belongs to low-porosity and low-permeability reservoirs. There are many factors that affect the productivity. Well logging data can reflect certain underground information, which is directly related to reservoir productivity. If you ignore the other effects, these geological parameters can explain some of the problems. According to the previous experience, the main factors affecting reservoir productivity are: porosity Φ, permeability K, effective thickness H, oil saturation So and other parameters. Combined with the test results of oil test and reservoir characteristics, the oil-water recognition standard of the 8th floor in the area was obtained. According to each parameter and test oil daily output diagram, the division of reservoir grade. It is imprecise to simply use one parameter to predict the productivity of reservoir. According to the characteristics of the reservoir in the Huanjiang area, the product of effective thickness × oil saturation is more consistent with the actual production status.
