地层倾角测井资料在山东马厂地区沙河街组沉积微相研究中的应用

本文论述地层倾角测井资料在山东马厂地区沉积微相研究中的应用。通过地层倾角资料进行特殊处理,结合岩心观察、常规测井资料,验证了倾角解释模式,成功地确定了砂体的沉积层理类型、古水流方向,指出了砂体延伸和增厚方向,阐明了下第三系沙河街组沙三中亚段四种沉积微相的沉积和分布特征。研究成果用于该区的砂层对比、开发注水、井网调整和预测砂体成因类型,指导该区的勘探和开发。

THE APPLICATION OF DIPMETER LOG DAIA IN THE STUDY OF MICROFACIES IN THE MACHANG AREA

This Paser discusses the application of dipmeter log data in the study of sedi-mentary microfacies in the Machang area. Through special processing of the dipme-ter log date combined with core observation and conventional log data, the authorsverified the model of dipmeter interpretation, determined successfully the beddingtypes of sandbody and the direction of paleocurrents and indicated the direction ofsandbody extension and thickening as well as the features of deposition and distri-bution of four sedimentary microfacies in the Shasanzhong Submember of Machang.These research achievements have been used for sand bed correlation,developmentand water inection, well network adjustment and prediction of the gentic types ofsandbody so as to direct exploration and development of the area.
