南堡5号构造带位于河北省唐山市曹妃甸区南堡油田内,主要发育有南堡5号背斜构造和北堡背斜构造,构造主体呈北东向展布,断裂发育,是南堡凹陷中重要的油气产层。为查明南堡5号构造油气分布规律及勘探前景,对现有钻井岩电资料及物探结果进行综合分析,认为南堡5号构造的主要沉积类型为以辫状河、扇三角洲、湖泊和湖底扇,其中东营组以扇三角洲前缘水下分流河道、河口坝、湖底扇中扇辫状沟道微相为最有利储集相带,馆陶组以辫状河心滩微相为较有利储集相带。南堡5号构造具有良好的油气成藏条件和开发潜力。
Nanpu 5 tectonic belt is located in Nanpu Oilfield, Caofeidian District, Tangshan City, Hebei Province. It is mainly composed of Nanpu No.5 anticline and Beibu anticline structure. The tectonic belts are developed in the NE direction and developed in faults. Depression in the important oil and gas production. In order to find out the hydrocarbon distribution regularity and exploration prospect of Nanpu 5 structural tectonic, a comprehensive analysis of existing drilling petrophysical data and geophysical results shows that the main sedimentary types of Nanpu 5 structure are braided river, fan delta, lake and In the Dongying Formation, the braided channel microfacies in the fan delta front subaqueous distributary channel, estuarine dam and sublacustrine fan are the most favorable facies belts, while the Guantao Formation is characterized by braided river hearth and microfacies Favorable reservoir phase belt. Nanpu No. 5 structure has good hydrocarbon accumulation conditions and development potential.
