Research and development of a new harmless treatment technology for drilling fluid wastes

The internal mechanisms of water-based drilling waste and oily drilling cuttings of oil-based drilling waste were researched. Firstly, efficient colloid breaker and efficient curing agent were developed, and new harmless technology of water-based drilling fluid waste has been formed. Secondly, new harmless treatment technology of oil-based drilling liquid with oil drill cuttings has been formed by physical, chemical and microbial technology. The two complete sets of technology have some advantages, such as simple operation, good treatment effect, small investment, and good reliability, which bring good social benefits and economic benefits.
