牛庄油田沙三段砂体成因类型及其形成机理探讨

A STUDY ON THE SEDIMENTARY ENVIRONMENTS AND ORIGINAL PROCESSES OF THE SANDSTONES IN NIUZHUANG DEPRESSION, EARLY OLIGOCENE(Es_3)

针对牛庄洼陷沙三段(Es_3)砂体成因本质的复杂性,以及由于过去地球物理和地质学家们对砂体多种解释的观点所带来的对本区进一步勘探与开发的困难等问题,本文应用了沉积学方法,结合地震地质学和测井资料综合研究的结果,提出了一个解释划分方案,认为牛庄洼陷砂体属牛庄三角洲—三角洲前缘斜坡扇的沉积物。

Directed against the problems of complexity in property generated by sand bodies of early Oligocene epoch (Es_3) in Niuzhuang depression, and the difficulties for further exploration and development brought from various points of view which are assigned by previous geophysicists and geologists, after getting the results from a sedimentology study, in combination with the synthesis findings from seismic stratigraphy and log data, a classification is presented in this paper that assigns sand bodies of Niuzhuang block to the process of Niuzhuang delta—delta front slope fan sedimentation.
