摘要

根据矿物成分、岩石类型、粒度分布及沉积构造等特征的研究

结合剖面上的韵律层序和测井曲线分析

认为黄骅坳陷南区侏罗系含油砂体主要是辫状河河道沉积。河道砂体的物源主要为北部燕山褶皱带

河流由北向南而流

形成水流汇集的主河道带。查明促进油气运移与聚集的构造环境

寻找控制油气分布的河道砂体

是今后本区中生界侏罗系的找油气方向。

Abstract

Jurassic oil-bearing sandbodies in the south of Huanghua Depression are typical braided channel sediments. They are chiefly composed of lithic arkose and feldspathic litharenite and are good reservoir rocks with great thickness

wide distribution

coarse grains and good physical property. The Huanghua Depression was a multi-center synclinal basin during the Jurassic

the Yenshan fold belt located in the north of the depression was the main source area. Thebraided channel sandbodies extended from north to south were an important factor to control the distribution of oil and gas.
