摘要

东濮凹陷沙三

3-4

亚段可划分为两个Ⅲ级层序

每个Ⅲ级层序都可划分为低位体系域、高位体系域.湖侵.湖退体系域.低位体系域主要发育低位三角洲沉积体系、低位扇沉积体系、千盐湖沉积体系.高位体系域主要发育高位三角洲沉积体系、高位湖底扇浊积砂沉积体系、辫状河沉积体系-浊积砂沉积体系.湖侵-湖退体系域主要发育湖泊扇三角洲沉积体系、辫状河沉积体系、湖退-湖进三角洲沉积体系、滩坝沉积体系.低位三角洲砂体、低位扇砂体是油气勘探最有利的砂体

其次是高位三角洲砂体、高位湖底扇砂体、辫状河砂体、扇三角洲砂体.

Abstract

3-4

submember of Dongpu Depression can be divided into two Ⅲ-grade sequences. Each of them consists of lowstand system tract

highstand system tract and lacustrine transgression-regression system tract. Low stand delta depositional system

lowstand fan depositional system and dry brine lake depositional system are mainly developed in the lowstand system tract. In the highstand system tract

highstand delta depositional system

highstand sublacustrine fanturbidite sand depositional system arid braided river depositional system-turdidite sand depositional system developed well. In the lacustrine transgression-regression system tract

lacustrine fan-delta depositional system

braided river depositional system

lacustrine transgression-regression delta depositional system and beach bar depositional system developed well. Low stand delta sand body and lowstand fan sand body are the most favorable ones for oil and gas exploration

and highstand delta sand body

highstand sublacustrine fan sand body

braided river sand body and fan-delta sand body are secondary.
