Cementing material condensation process monitoring method and application thereof

Abstract

Disclosed is a cementing material condensation process monitoring method. According to the method, an ultrasonic testing method, a conductivity testing method and a temperature testing method are adopted comprehensively for monitoring the condensation process of cementing materials, test advantages of the three methods are fully used, the three testing methods are combined to overcome the drawbacks in the three testing methods, the condensation process of the cementing materials is monitored all sidedly to acquire effective and accurate condensation data, and the condensation process is grasped in real time. Technicians in the field can acquire the effective and sensitive condensation data on the basis of utilizing the method, so that convenience is effectively brought to the technicians in the field to conduct adding types, adding number and the like of additives and raw materials.

Description

Technical field

[0001] The invention relates to a method for testing gel material coagulation process and specific application equipment under the method. technical background

[0002] The coagulation behavior of gelling materials varies greatly, and it is affected by factors such as the variety and quality of gelling agents, additives, temperature, pH, and raw material activity. Measuring and analyzing its coagulation behavior and mastering its laws can effectively guide the selection of additives and raw materials, the optimization of material formulations and the improvement of construction techniques. At present, our country's research in this area basically stays on the measurement of a single index. The measuring instrument includes a Vicat meter (that is, a metal rod is used to continuously puncture within a specified time, and the degree of condensation is judged by the state of sliding after puncturing), Hydration exothermic instrument (that is, real-time monitoring of ...
