Turbidite Sand:A New View on Sedimentary Facies of Pliocene Zhujiang Member-2 in DF-A Gas Field, Yinggehai Basin
摘要
Abstract
The depositional model of the Pliocene Yinggehai Formation in DF-A gas field of Yinggehai Basin is controversial. Based on the comprehensive analysis of well core, logging data, and seismic multi-attributes, three sedimentary microfacies developed during Yinggehai Member-2 are turbidite sand, foreshore dam, and offshore mud. Controlled by the slope break of the basin and the occurrence of diapir during the depositional period, there developed sheet-like turbidite sand mainly in Ⅲ and Ⅱ gas group which derived from the western sea fan, and developed foreshore dam deposition mainly inⅠ gas group, and developed offshore mud widely in each gas group. This recognition of turbidite sand in Yinggehai Member-2, which changed the pattern of the foreshore dam derived from the eastern Hainan Island, have played an effective role in the later development and adjustment.关键词
