【摘要】 以侧向约束应力状态作为地应力的参考应力状态,利用常规测井资料对岩石力学参数进行分析处理,采用葛氏地层应力经验关系式,建立地应力的计算模型。滨670井、滨660-665区块进行了单井分层地应力及地层岩石力学参数分析计算,用于滨670井限流压裂设计以及滨660-665区块极限注水压力的确定,取得了理想的效果。更多还原

【Abstract】 An earth stress calculation model is established by referencing lateral constrained stress state,analyzing and processing rock mechanic parameters with conventional logging data,and using Ge empirical equation.Single well zonal earth stress and rock mechanic parameters are calculated for limited entry fracturing in Well Bin670 and for determination of the extreme injection pressure in block Bin660-665.Acceptable result has been achieved.更多还原
