以渤海湾几个发现白云岩的油田为例,结合白云岩的几种主要成因理论,从岩性特征、测井曲线形态、薄片鉴定、岩石成因方面对渤海湖相白云岩进行分析研究,研究表明白云岩分布受气候和古地貌控制。根据湖平面变化和古地貌,结合沉积环境、地震,利用层拉平技术探讨了白云岩的分布特征。

Taking fields of Bohaiwan Basin as an example and combining with several forming theory of dolomite, lacustrine dolomite reservoirs in Bohai oilfield was discussed in terms of lithology characteristics, logging trace, thin section analysis and origin of lacustrine dolomite.It's found that the distribution of dolomite is dominated by climate and palaeogeomorphology, and the distribution of dolomite was summarized based on lake level change, palaeogeomorphology, seismic data, depositional environment and lay flattening technique.
