板桥油田板二油组扇三角洲沉积与油气关系

The relationship between fan delta deposition and gas oil in Ban 2 formation of Banqiao Oilfield

通过对黄骅拗陷板桥油田板二油组扇三角洲沉积的古沉积背景和沉积特征的研究，将扇三角洲前缘亚相划分为水下分流河道、水下河道间和席状砂微相。认为其中的水下分流河道砂体厚度大，分布范围广，物性好，是区内重要的储集层。

Basing on research to sedimentary character of fan delta in Ban 2 Formation of Banqiao Oilfield in Huanghua Depression, delta front is divided into submerged distributary channel, submerged distributary interchannel and sheet sandbodies microfucies, and among them, submerged distributary channel is main reservior bed in study area.
