中文摘要:针对5000米地质岩心钻探基础准则与依据缺失,油气钻井与岩心钻探工艺及装备差异大等问题,本文梳理分析了国内外深部地质岩心钻探口径系列及管柱规格,厘定了基本外界条件及相互关联要求,开展了特深孔岩心钻探环空水力学计算与绳索取心钻杆的等强度设计,初步构建了以绳索取心钻进工艺为主体的5000米特深孔钻探口径系列与钻(套)管柱规格。

Discussion on Hole Diameter and Drill Rod Specification and Casing Program of Ultra-deep Geological Core Drilling
Abstract:Aiming at the problems such as the lack of basic criteria and bases for 5000 meters geological core drilling, the great difference in drilling technology and equipment between oil and gas drilling and core drilling and so on, this paper summarizes and systematically analyses the diameter series and pipe string specifications of deep geological core drilling at home and abroad. On this basis, basic external conditions and interrelated requirements are defined and equivalent strength design and annular hydraulic calculation of wire-line drill string for ultra-deep hole core drilling are carried out. Diameter series and drill string and casing string specifications of 5000 meters ultra-deep hole drilling are preliminarily constructed, which are with the wire-line drilling technology as the main part.
