Research on Quality Evaluation Methods of Ultra-Low Density Cementing in Oil Well Cementing
With the development of cementing technology,ultra-low density cement slurry has been widely used,especially for low pressure leak,narrow density window of the layer,ultra-low density cement slurry has solved the problems of insufficient cement return height and cementing loss,and improved cementing quality significantly.In order to accurately evaluate the cementing quality of ultra-low density cement slurry,the laboratory test method is used to study the influence of temperature and density on the strength and acoustic characteristics of ultra-low density cement paste,this paper discusses the improvement method of cementing quality evaluation of ultra-low density cement,which lays a foundation for improving cementing quality of ultra-low density cement.
