【摘要】 岩石力学参数在岩土工程及石油工程设计与计算中具有重要作用,其合理与否直接关系到相关工程分析设计的可靠性。在总结前人工作的基础上,基于任丘油田的现场实际资料,利用概率统计的方法,研究了小样本条件下岩石力学参数概率分布的推断方法,确定了该油田目标储层岩石弹性模量及泊松比的概率分布模型,回归拟合了其分布函数表达式。更多还原

【Abstract】 Rock mechanical parameters play an important role in the design and calculation of geotechnical engineering and petroleum engineering,its rationality is directly related to the reliability of the analysis and design of relevant engineering.Based on the summary of predecessor’s fruit and the actual data of Renqiu oilfield on the site,the inference method of probability distribution of rock mechanical parameters for small samples is studied by probability statistics,the probability distribution model of rock elastic modulus and Poisson’s ratio of target reservoir in the oilfield are determinded,and the distribution function expression is identified according to regression fitting.更多还原
