八面河斜坡带潜山形成机制与勘探潜力

On Formation Mechanism and Exploration Potential of Buried Hills in Bamianhe Slope Belt

八面河地区潜山发育,分布广泛,且具备基本的成藏地质条件,是东营凹陷的一个重要的勘探领域。利用钻井、测井、地震及分析化验等资料,从潜山成因类型和成藏的基本地质条件方面探讨古潜山的成藏模式。研究结果表明,郭井子潜山带主要形成复合型潜山油气藏,草桥潜山带和广饶-羊角沟凸起带为残丘型层状油藏;羊口潜山带和沙子岭潜山带为断块型块状油气藏。

In Bamianhe Oil Field, buried hills are well developed, widely distributed and have basic petroleum geolog- ical conditions. Therefore, Bamianhe Oil Field is an important exploration area in Dongying Depression. The hydro- carbon accumulation patterns of buried hills are discussed with respect to their genetic type and basic petroleum geo- logical condition based on the drilling, logging, seismic, analytic and testing data. The research result suggests that complex buried hill reservoirs occur mainly in Guojingzi buried hill zone pimple layered reservoirs in Caoqiao burial hill zone and Guangrao--Yangjiaogou uplift zone, and fault--block massive reservoirs in Yangkou and Shaziling bur- led hill zones
