    Abstract
  • Acid soluble cement is generally used in controlling severe mud losses. This technology is presently not mature. Acid soluble cements presently in use are mainly composed of cement and carbonate. Acid soluble cements are unable to satisfy the need of field application, some of them have acid solubility of less than 90%, while others need a long time to dissolve. It was found from the evaluation and analysis of the main factors affecting the acid solubility of cement that by optimizing the concentration and particle sizes of the carbonate added to the cement, the solubility of cement in acid can be increased to above 90%, still it is very difficult to increase the acid solubility to above 95%. To further increase the acid solubility of cement, a dissolving accelerator has been developed, which, when used with organic foaming agents and saturated alkanes (as stabilizer), can decompose at alkaline condition and a certain temperature to produce some small gas bubbles. These bubbles can be dispersed uniformly into a cement slurry and generate small dissolution holes in the gelled cement which serve as channels for acid dissolution. In this way the percent dissolving of cement in acid is greatly increased; 96% of the set cement can be dissolved in 30 min. The properties of the cement slurry in field application was easy to adjust. The application of this cement slurry not only solved the problem of severe mud losses, it also helped protect the reservoir from being damaged.
