摘要:

本文利用数量化理论Ⅰ的原理和方法,综合考虑了钻井循环过程中定量变量和定性变量对钻井循环压降的影响关系,并通过对5口井共54组实钻数据的处理,建立了钻井循环压降计算的数量化模型。结果表明,此模型能就定性变量(如泥浆类型)对循环压降的影响作出定量分析,并有较好的计算精度,可以弥补理论计算法的不足之处。

Abstract:

On the basis of the principle and method of the quantified theory Ⅰ, the influence of quantitative and qualitative variables on the circulating pressure of drilling fluids is analysed. The quantified model of calculation of the pressure is set up through the treatment of 54 groups of drilling data in 5 wells. The model ean quantitatively analyse the effect of qualititative variables (such as mud types) on the circulating pressure. And the model has also better caleulating precision to remedy the defects of theoretical calculating method.
