Abstract

Abstract:

Deep sea submarine fan is one of the key sedimentological subjects for oil and gas exploration， while shallow sea submarine fan is comparatively less documented. To fill up the gap， the shallow sea multi-stepped submarine fans in the Miocene Huangliu Formation of the Dongfang 1-1 gas field in the Yinggehai Basin are thoroughly investigated to determine their genetic mechanisms and distribution pattern of reservoirs by using core， drilling， seismic， lab test data， etc. The following results are obtained. ① The multi-stepped submarine fans host channels， sheet sands and distal silts， of which the channels are medium- to fine-grained sandstone with lenticular-shaped high-amplitude seismic reflections and low seismic impedance values， the sheet sands are dominantly fine-grained sandstone and siltstone with parallel beddings， showing high-amplitude seismic reflections and lower seismic impedance values （compared to channel deposits）， and the distal silts are commonly mudstone and siltstone， showing low-amplitude seismic reflections and high impedance. ② The channels， forming the main parts of the fans in the northwest， middle， and southeast of the study area， are NW-SE oriented and can be divided into three steps. The sheet sands are developed at flanks and terminals of the channels. The distal silts are generally formed at the margin of the fan. ③ Both the channels and sheet sands are considered potential reservoirs with the latter being slightly higher in reservoir quality than the former. They are usually disconnected， quite ideal for the formation of lithological and stratigraphic traps. ④ The fans are suggested to have experienced an early supercritical to subcritical flow transform stage and a late filling-overbanking stage. During the early deposition of the Huangliu Formation， high-energy gravity flow led to the formation of multi-stepped channels via transformation from supercritical to subcritical flow； and during the late deposition of the Huangliu Formation， flow transformation was replaced by filling-overbanking as the gravity flow got weakened.
