1前言在现在流行的层序地层理论模型中，深水沉积物沉积平低水位体系城。该城由盆底扇、隆坡商和进积楔形复合体组成。盆底扇被认为是具吸引力的烃类远景区。理论模型预测，企底扇具有以浊积岩为主的特殊富沙特征，它表现为“由作为舌状体或席状体沉积于深海背景的块状砂组成的 1 Preface In the popular theoretical model of sequence stratigraphy, deep-water sediments are deposited in flat low-water system cities. The city by the pelvic floor fan, Long Po business and wedge-shaped complex formed. Pelvic fan is considered an attractive hydrocarbon prospect. The theoretical model predicts that the fan has a special turbid-rich sand-rich characteristics of sand, which manifested as "the tongue or body as the deposition of the sand in the background of deep sea composed of lump sand
