Water-based Waste Drilling Fluid Sound Processing

The waste of the water-base drilling fluid (WWBDF) is the great waste residue during the exploration and exploitation in the petroleum industry. If not disposed of freely letting into environment, it will pollute the environment and cause incredible damage. At present, people have not paid more attention to think how to deal with it, and the disposing methods are simple correspondingly. The thesis stands on the environmental points of view to analyze and develop the disposing methods, thus attain the harmless disposing purpose. The thesis mainly contain following several parts: Biological Degradability Test to the Additives; Study on Additives' Biologic Toxicity; Land Spray Treatment Technology of the WWBDF; Solidification Treatment Technology of the WWBDF; Environment pollution Assessment to the WWBDF synthetically. Through these researches attain a series of WWBDF harmless treatment technologies.
