摘　　要：详细介绍了岩石抗压强度的测试目的、测试方法及其影响因素,具体分析了岩石抗压强度与声波时差、岩石密度、孔隙度以及地层深度等参数之间的关系。结合测井解释资料,根据概率论与数理统计基本理论,建立了岩石抗压强度与声波时差、地层深度之间的二元回归模型。利用该回归模型进行抗压强度的计算,可以为建立油井出砂的理论预测模式提供较为准确的岩石抗压强度数据。The testing goals, testing methods and influencing factors of rock compressive strength are described in detail, And also the relations among rock compressive strength, sonic differential time, rock density, rock porosity and strata depth are analyzed. According to the logging interpretation data, the regression model about rock compressive strength, sonic differential time and strata depth has been established with the theory of probability and mathematic statistics. The computed rock compressive strength with the established regression model can support exact compressive strength for the establishing of sand prediction model for oil well.
