摘要
在地质综合研究的基础上,基于测井曲线活度分析,结合测井小波分析以及地层旋回特征,进行地层旋回划分方法的研究,并以HSS油田H1518井为例,运用以上方法进行HSS油田H1油层组的地层旋回的划分和地层精细对比。研究结果表明,在标志层研究的基础上,利用测井曲线的活度及小波分析,结合沉积旋回特征研究,可有效进行沉积旋回的划分,HSS油田H1油层组按照旋回特征划分为1个砂层组、3个砂层和7个小层。
The supplementary method of stratum sedimentary cycle division have been studied based on activity analysis,joining with wavelet analysis and stratum sedimentary cycle characteristics,after the comprehensive geology research.In the same time,take well H1518 in HSS oilfield as an example,to explain how to use the methods in stratum sedimentary cycle division and stratum fine contrast.The results show that the sedimentary cycle can be divided effectively from well logging data based on activity and wavelet analysis,joining with sedimentary cycle characteristics research,after key stratum be decided,stratum cycle division of H1 formation in HSS oilfield been done,and H1 formation can be divided into 1 sands group,3 sand layer and 7 single layer.
