Research and application for the non-landing treatment technology of water-based drilling solid-liquid waste in Northwest China

Abstract

Water-based drilling solid-liquid waste is the most common environmental pollutant in the process of oil and gas exploration and development. Due to leakage or untreated discharge, these drilling solid-liquid wastes enter the atmosphere, water bodies, and soil, and cause serious pollution to the surrounding ecological environment. At present, how to reduce the heavy metals and other toxic and harmful components in water-based drilling solid-liquid waste, make it meet the discharge standards or recycle it is a major problem that plagues the sustainable development of oil and gas fields. This article introduces the sources and characteristics of water-based drilling solid-liquid waste, summarizes the domestic research status of solid-liquid waste treatment technology for foreign water-based drilling, analyzes the characteristics and advantages of drilling waste non-landing technology treatment. It is pointed out that it is necessary to adopt drilling water-based solid-liquid waste non-ground treatment technology in the exploration and development process of oil and gas fields in Northwest China, and it has good application prospects.
