漂珠-微硅复合低密度水泥浆体系在苏丹1-2-4区块应用中的抗压强度与密度和温度之间的相关性研究

The study of the correlation between the compressive strength and densityand temperature of the Low density and high strength cement slurry system

固井水泥浆抗压强度是固井质量的重要参数,而地层温度和水泥浆密度是影响抗压强度的重要参数指标。本文结合近年来苏丹1-2-4区块漂珠+微硅复合低密度高强度水泥浆体系的广泛应用与国内学者对该水泥浆体系进行的室内理论研究,利用多元回归分析方法对实验所得该水泥浆体系的抗压强度等重要参数数据进行线性回归分析,得到线性回归模型。结果表明:漂珠+微硅复合低密度高强度水泥浆体系抗压强度与实验温度(模拟地层温度)、水泥浆密度之间确实存在着线性相关关系,应用回归模型可以利用温度和密度数据来计算抗压强度,从而对固井现场施工工作起到指导作用。

Cementing slurry compressive strength is an important parameter of quality,the formation temperature and the density of cement Slurry are the important parameters affecting the compressive strength indicator.In this paper,block of Sudan in recent years 1-2-4 system of low density and high strength cement slurry wide range of applications and domestic scholars in the slurry system for theoretical studies of indoor,The use of multiple regression analysis derived from the experimental system,the compressive st...
