东海平湖油气田八角亭构造区H4段沉积展布特征和相模式研究
|
摘要
八角亭构造是平湖油气田的潜力区块,随着老区可动用储量的不断减少,澄清H4砂层组的沉积相展布和相模式是油藏挖潜的前提和迫切需要。结合岩芯、测井进行了层序地层学研究,将H4砂组划分为四个亚段并进行了精细地层对比,通过地震反演资料追踪确定了砂体平面分布特征。H4沉积时期是三角洲不断向前推进的过程,H4d-b沉积时期水体相对校深,砂体规模小、非均质性较强;H4a沉积时期水体变浅,物源充足稳定、砂体叠置交错、平面上连片分布,连通性好。
The Bajiaoting structure is the potential oil source of the Pinghu Oil-gas Field,with the decline of available residual oil in old areas,implementation of facies distribution and facies model of the Member H4 is urgent and essential to,tap potential reservoir in this area.Combined with core and well logging data,the sequence stratigraphy of the H4 interval was studied.The Member H4 is divided into four 5th order sequences.With fine stratigraphic correlation using seismic inversion tracking,the flat distribution of sandbodies is determined.Delta deposition constantly moved forward during the H4 period.H4d-b interval is of relatively deep water,and sand formed at that time is of small scale and strongly variable.In contrast,H4a interval represents shallow water deposits,and with sufficient stable source,sand bodies are widely distributed.
