Abstract

Abstract:

Deep and ultra-deep layers within petroliferous basins have emerged as new targets in global oil and gas exploration. However， the major factors influencing the development of high-quality reservoirs within these layers remain poorly understood， posing challenges for effective exploration. This study focuses on the coarse-grained siliciclastic reservoirs in the nearshore subaqueous fan in the lower submember of the 4^th member of the Shahejie Formation in the steep slope zone of the Minfeng sub-sag， Dongying Sag. By combining methodologies including casting thin section observation， scanning electron microscopy （SEM）， cathodoluminescence microscopy-based identification of minerals in thin sections， fluid inclusion thermometry， and paleopressure reconstruction， as well as the analytical results of the burial and thermal history， we comprehensively examine the reservoirs’essential characteristics， hydrocarbon charging history， pressure evolution， and factors controlling the development of high-quality reservoirs. The findings include：（1） The coarse-grained siliciclastic reservoirs in the study area are predominantly lithic arkoses and feldspathic litharenites. They exhibit medium to strong compaction and are dominated by ferrodolomite cementation， followed by quartz overgrowth. They show overall weak dissolution dominated by feldspar dissolution. The reservoir spaces comprise mostly primary pores， along with some others developed from feldspar dissolution. （2） Two oil charging stages and one natural gas charging stage were identified： an early mature-oil charging between 37.2～25.8 Ma and a later highly-mature-oil charging from 12 Ma onwards. The natural gas charging has lasted till now since 3.6 Ma. （3） The reservoirs have experienced two distinct pore pressure-increasing cycles： 45～24.6 Ma and from 24.6 Ma to present， corresponding to the two hydrocarbon charging stages. （4） Favorable lithofacies lay the foundation for the development of high-quality reservoirs dominated by primary pores in the study area. The inhibitive effects of overpressure hydrocarbon charging on compaction and cementation are crucial to the development of high-quality reservoirs. The weak dissolution of feldspar and carbonate minerals in the deep closed system leads to a low increment in porosity. However， the reduction rate of the reservoir porosity with depth declines significantly at burial depths beyond 3 750 m， and the development of deep high-quality reservoirs dominated by primary pores expands the lower limit of depth for exploration.

Key words: sedimentation, diagenesis, overpressure hydrocarbon charging, reservoir characteristics, lower submember of the 4^th member of the Shahejie Formation, Minfeng subsag, Bohai Bay Basin
