【摘要】 通过岩心、薄片、粒度、测井及地震资料综合分析,在霸县凹陷鄚州—高家堡地区沙三段首次发现了滑塌浊积岩,并对其沉积特征进行了研究。结果表明,研究区滑塌浊积岩的粒度较细,成分成熟度和结构成熟度都较低,结构和构造均反映了沉积物滑塌再沉积的特点,沉积单元从下到上可概括为鲍马序列:平行层理段(B)、流水沙纹层理段(C)、水平层理段(D)和泥岩段(E),常发育BCDE,BCD,BCE和DE型组合序列。霸县凹陷鄚州—高家堡地区沙三段滑塌浊积岩是三角洲前缘砂体在同沉积断层频繁活动和水体振荡作用下滑塌形成的,具备良好的生储盖组合和较大的油气勘探潜力。更多还原

【Abstract】 Based on comprehensive analysis of core.thin section,grain size,well logging and seismic data,it is presented for the first time that fluxoturbidite were discovered in Maozhou and Gaojiapu of Baxian Depression.and the features of fluxoturbidite were studied hprein.it is demonstrated that fluxoturbidite has finer granularity and lower maturity in composition and texture.Moreover,the features of fluxoiurbidite can be reflected by composition and structure and can be described by Bouma sequence from bottom to top,that is,B.parallel bedding segment ;C.water current ripple bedding segment:D,flat bedding segment;E.mudstonr segment,the sequence association.such as BCDE.BCD,BCE and DE are often observed.Fluxoturbidite,formed by slump of the delta sand-stones in the circumstances of disturbing water and syndepositional fault frequently action,has a good source-reservoir-cap rock combination and exploration potential.更多还原
