压力、温度对泡沫水泥密度的影响

The influence of pressure and temperature on the density of foam cement

泡沫水泥是一种由氮气、混合水、水泥组成的三相水泥,在井眼条件下,受井下温度、压力的影响,实际密度与地面密度相差较大。利用一种静态模拟实验装置的研究方法,对泡沫水泥密度随压力、温度的变化进行了研究和分析。

A new testing equipment for foam cement density is presented . It is shown that the density of foam cement is affected greatly over 50 C and lowly below 50 C at constant pressure , and affected greatly below 2 MPa and lowly over 2 MPa .
