摘要： The present invention relates to a method for determining mechanical parameters of a cementitious system, on the basis of time, and on the basis of the fineness of the cementitious system, pressure and/or temperature, representative of the in situ conditions found in wellbores. The initial composition of the cementitious system, the fineness Φ thereof and the speed of the compression waves on the basis of time Vp(t) are the only input data of the method. Said method comprises: ▪ a step A of estimating the degree of hydration of the cementitious system on the basis of time α(t) from Vp(t), at a pressure P1 and a temperature T1; ▪ a step B wherein α(t) is determined on the basis of desired values of fineness Φn of the cementitious system, pressure Pn and/or temperature Tn; ▪ a step C wherein the composition of the cementitious system is determined on the basis of time C(t) and on the basis of desired values of fineness Φn of the cementitious system, pressure Pn and/or temperature Tn from α(t) determined in step B; ▪ and a step D of determining at least one mechanical parameter of the cementitious system on the basis of time and on the basis of desired values of fineness Φn of the cementitious system, pressure Pn and/or temperature Tn, from C(t) determined in step C. According to the method of the invention, these parameters can be determined while the cementitious system is still very young. In particular, the parameters of static deformability and hydro-mechanical coupling parameters are determined by the method according to the invention.

摘要翻译：本发明涉及一种用于基于时间确定水泥体系的机械参数的方法，并且基于水泥系统的细度，压力和/或温度来代表在井筒中发现的原位条件。基于时间Vp（t），胶结体系的初始组成，其细度Φ和压缩波的速度是该方法的唯一输入数据。所述方法包括：步骤A，基于来自Vp（t）的时间α（t），在压力P1和温度T1下估算水泥体系的水合度; 步骤B，其中α（t）基于水泥系统的期望值Φn，压力Pn和/或温度Tn来确定; 步骤C，其中基于时间C（t）确定胶结体系的组成，并且基于胶结体系的细度Φn的期望值，压力Pn和/或来自α（t）的温度Tn，其确定在步骤B; 以及步骤D，根据时间和基于胶结体系的细度Φn的期望值（Pn和/或温度Tn）来确定水泥系统的至少一个机械参数，从C（t）确定的步骤C.根据本发明的方法，可以确定这些参数，同时水泥系统仍然非常年轻。特别地，静态变形性和水力耦合参数的参数由本发明的方法确定。
