摘要
地下砂体存在不均匀性,导致利用油层平均体积法劈分地质储量偏大或偏小.分析影响储量的因素,推导单井地质储量与有效厚度和单井控制含油面积之间的关系.通过该关系可将油层组地质储量准确劈分到单井,进而劈分到井组和各沉积单元,以根据不同的研究对象进一步加密挖潜.
This paper dealswith the association of the geologic reserves of individual wells,effective thickness and using individual wells to control the oil-bearing area.In the light of the present problem about the geologic reserves of reservoir formation at the high water-cut stage,we begin with the factors of affecting reserves.We can divide the geologic reserves of reservoir formation into individual wells,further into well formation and each sedimentary unit.We have solved the difficult problem of dividing rationally the geologic reserves of reservoir formation into individual wells,different well patterns and different sedimentary units,clarified the distribution characters of geologic reserves.It is good for developing further infilling tapping potential work according to different objects of research.
