摘　　要：本文从Ｘ射线的性质，以及Ｘ射线与物质作用的机理出发，对井液效应进行了研究，并对其影响过程进行模拟。在理想井液模型上，推导出Ｘ射线活度与钻孔参数的数理关系。在此基础上，进一步研究得到了能适应野外多变情况的井液效应校正公式（ＣＢＷＥ）和方法。Based on the X -ray property and the action mechanism of X-ray on mass,the study on the borehole water effect was made and the process of its influence was simulated in this paper. The mathematical relationship between X-ray activity and borehole parameters was inferred on an ideal boerhole water model. On this basis,the correction formula and method of boerhole water effect (CBWE)applicable to changeable conditions in the field were obtained after the further study had conducted.
