肃宁地区Es1~x段普遍发育页岩(灰质页岩、油页岩),其单层厚度较大,具有纵向上集中,横向上稳定的特征。页岩与优质烃源岩共生,形成源储一体或互层状分布,有利于油气就近运移成藏。页岩的页理发育,脆性大,有利于压裂改造。据现有钻探资料分析,页岩油气具有较好的勘探开发前景。 Shales (gray shale and oil shale) are widely developed in the Es1 ~ x stage of Suning region. The monolayer has a large thickness and is longitudinally concentrated and laterally stable. Shale and high-quality source rock symbiosis, the formation of source or reservoir integrated or stratified distribution, is conducive to the recent transport of hydrocarbons into the reservoir. Shale page management, brittle, is conducive to fracturing. According to the existing drilling data analysis, shale oil and gas has good prospect of exploration and development.
