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。
Rock mechanics parameters play an important role in geotechnical engineering and petroleum engineering design and calculation. Whether it is reasonable or not is directly related to the reliability of relevant engineering analysis and design. Based on the previous work of Renqiu Oilfield, based on the field actual data of Renqiu Oilfield, the probabilistic statistical method is used to study the method of estimating the probability distribution of rock mechanics parameters under small sample conditions. The rock mass elastic modulus And Poisson’s ratio probability distribution model, the regression fit the distribution function expression.
