摘要
Abstract
Cenosphere used as a mitigation material in low density cement system which widely used in the formation of low pressure leaky cementing project .Aim to fully explore the mechanical properties of the floating bead low density cement , the manuscript investigated the compressive strength and tensile strength in different temperature condition .Simulated the underground environment to operate the stress-strain testing , and analyze the microscopic morphology and pore size distribution of the samples .The results showed that the cenosphere has a good compatibility with cement .Cenosphere has the rigid non-crack resistance properties and makes the cement stone has a higher compressive strength and lower tensile strength .The pore size distribution of cement stone cured in high temperature has a widely range compared with the cement cured in low temperature .The density of high temperature cured cement is lower too.关键词
