Research Progress on Acid Gas Contamination of High-Density Drilling Fluids
Acidic gas has a great impact on the performance of high-density drilling fluids.The rheological properties of drilling fluids are difficult to control and the filter loss performance deteriorates.Therefore,research on treatment methods for acid gas pollution in high-density drilling fluids is urgent.This article reviews the research progress on the contamination mechanism of high-density drilling fluid by acid gas,the detection methods of acid gas contamination of high-density drilling fluid and the characterization methods of system microscopic properties,as well as the performance optimization treatment methods of high-density drilling fluid contaminated by acid gas.The existing problems of current acid gas prevention measures and future development are analyzed,in order to provide a reference for the research and development of performance control after acid gas invades high-density drilling fluids.
