新场气田岩土工程地质特征及基础方案优选

摘要

在对钻井区块已有的钻前和建筑工程勘察资料归纳总结的基础上,详细分析评价了岩土的工程地质条件及其横向分布规律,并结合石油钻井各类钻机设备的设计荷载,以及建筑地基基础设计规范要求,对该区不同性质地基土钻井设备基础方案进行了优选,为该区后续开展钻前工程设计奠定了理论和实践基础。%Bases on the summary of construction engineering survey data before drilling in drilling block,this paper specifically analyzes and evaluates geotechnical engineering conditions and horizontal distribution laws.Combining with design load of various drilling facilities of petroleum drilling and building foundation design norms,it optimally selects basic drilling facilities scheme with different foundation soil in this region,which has laid theoretical and practical foundation for the continuous pre-drilling engineering design.
