Abstract
A silicate water-based drilling fluid for coalbed methane wells and an application are provided. In terms of parts by weights, raw materials of the silicate water-based drilling fluid comprise: 100 parts of water, 1-3 parts of bentonite, 1-5 parts of pH regulator, 3-5 parts of silicate, 2-4 parts of silicate stabilizer, 0.1-0.15 parts of tackifier, 2-4 parts of filtrate reducer, 3-5 parts of auxiliary inhibitor, 1-2 parts of activator, 2-4 parts of plugging agent, and 2-4 parts of lubricant. The silicate water-based drilling fluid for coalbed methane wells has good rheological properties, filtration performance, plugging performance and lubrication performance under a low temperature environment, and is more suitable for coalbed methane well drilling operations.
