富台油田古潜山储集层特征及分布模式

富台油田主力含油层位为下古生界及第三系沙三段上亚段，属复式油气藏。其中下古生界古潜山油气藏属层状油气藏。储层主要为内幕孔洞型储层和内幕裂缝型储层。本文从地质特征入手，分析了下古生界的储集空间类型，建立了古潜山内幕储集层分布模式，其结果对车镇凹陷北带乃至济阳坳陷同类型的古潜山勘探有重要的借鉴意义。

Characteristics and distribution mode of buried hill reservoirs in Futai oilfield

Major oil - bearing horizons of Futai oilfield were lower Palaeozoic and the upper member of Sha 3 formation of Tertiary, belonging to complicated reservoir. The buried hill reservoir in lower Palaeozoic was a layered reservoir, with inner vug and inner fracture reservoirs as major types. Starting with geological characteristics, this paper analyzes the reservoir space of lower Palaeozoic and establishes the distribution mode of inner buried hill reservoirs. The result of this study is an important reference to exploration of similar buried hills in the north of Chezhen sag or even Jiyang depression.
