Abstract: Drilling solid waste is an inevitable product of oil and gas exploration and drilling. Most solid waste, such as waste sludge from cleaning drilling fluid tanks and square wells, waste drilling fluid from drilling process and completion, sludge from waste water treatment, etc., have very high water content. Reduction, resource utilization and harmlessness of solid waste treatment are three principles of solid waste disposal. Reduction of drilling solid waste treatment is very important. This paper discusses in detail the characteristics of drilling solid waste and summarizes the technical equipment of solid waste solid-liquid separation. It compares and analyzes the application scope and advantages and disadvantages of various kinds of separation technical equipment. This is of certain guiding significance for environmental protection workers and relevant decision makers in oil and gas field.

Key words: drilling solid waste, separation, disposal, reduction, technical equipment
