合水地区长6油层组深湖浊积沉积特征

The characteristics of deep lake turbidity deposit in Chang 6 oil reservoir group in Combination area

根据岩芯、镜下的观察、测井资料等一系列区域地质背景的综合分析,对合水地区浊积沉积特征进行了讨论,认为合水地区浊积沉积主要发育长6油层组,三角洲分为了三个沉积亚相,6个沉积微相,讨论了湖底滑塌浊积扇的形成条件,描述了其剖面、展布特征,建立了沉积相沉积模式,为岩性地层油气藏的勘探提供理论依据。

Based on the comprehensive analysis of the geological background of a series of areas,such as the core,the observation under the mirror,and the logging data,the characteristics of turbid sediments in the confluence area are discussed. It is believed that the turbid sediments in the confluence area are mainly developed in the 6 oil layers and the delta is divided into three sedimentary subphases. Six sedimentary microfacies discussed the formation conditions of the slippery turbid fan at the bottom of the lake,described its profile and distribution characteristics,and analyzed the geological significance of the area as a deep lake turbid deposit.
