With the emphasis on environmental protection, drilling process in the disposal of waste drilling fluid is also more and more attention by drilling people in recent years. Based on the current development status of waste drilling fluid disposal method in home and start from waste drilling fluids of the China, this paper discussed respectively of the processing method of based waste drilling fluid in the disposal of waste drilling fluids, and the field application situation. It is more convenient to choose the disposal method of abandoned drilling fluid which is suitable for a certain area, and it will be helpful to the field work.

The potential benefits of creating intelligence are huge, Oil, as the world’s main energy material, is an important energy that relates to the national economy and people’s livelihood. In recent years, with the rapid development of national economy and society, the demand for energy has also increased. In this context, deepwater energy has become the focus of attention. In this paper, the research results of and the challenges faced by deepwater drilling fluid at home and abroad in recent years are summarized.

In this paper, a BP neural network model with 5-9-6 structure is constructed according to various fault gases and different fault types ofWater-based drilling fluid and synthetic-based drilling fluid. While there are few studies relating to oil-based drilling fluid, which is attributed to the potential toxicity of conventional oil-based drilling fluid to the marine environment. However, oil-based drilling fluid is excellent in protecting the borehole stability. To this end, an environmentally friendly deepwater oil-based drilling fluid was developed based on the traditional oil-based drilling fluid. With the advantages such as good borehole stability and good wettability, this drilling fluid will not pollute the marine environment, is resistant to high temperature, and protects hydrocarbon reservoir, which is of great significance for rational exploration and development of deep-sea resources.
