(1) Promote cleaner production, address the issues first and address the root causes. At present, there is an urgent need to control the source of waste drilling fluid, promote cleaner production, strengthen solids control, and reduce emissions. Improve the performance of drilling waste management system through solids control, and attach importance to reuse technology to reduce comprehensive treatment costs. When drilling, use environmentally friendly chemical treatment agents and additives to replace more toxic chemical treatment agents and additives, so as to achieve source control and clean production.

(2) Develop low-cost and high-performance environmentally friendly drilling waste management system. At present, environmentally friendly drilling fluids such as synthetic base and methyl glucoside developed abroad have non-toxic and biodegradable properties, but their high cost cannot be widely used. The low-toxicity oil-based drilling fluids and new synthetic-based drilling fluids developed in recent years also have various effects on the environment during use. Therefore, in future research, attention should be paid to low-cost natural polymer materials and various environmental protection treatment agents. The modification and perfection of the product, as well as the research on the use technology of non-toxic and non-polluting organic and inorganic salts.
(3) Research and development of new type of drilling waste management system and general technology. Due to the different properties of waste drilling fluids produced in various domestic oilfields, it is necessary to add special chemical treatment agents for treatment. At the same time, because of the addition of different chemical treatment agents, the composition of the waste becomes more and more complicated, which is harmful to the environment. It’s getting bigger and bigger. If a new type of environmentally friendly treatment agent is developed, it can reduce the damage to the environment in the later period, such as the excellent flocculation, non-pathogenicity, safety, and biodegradability of natural organic polymer flocculants, which will attract more and more attention. Modifying natural polymer flocculants to prepare environmentally friendly treatment agents will certainly be widely used. In addition, it can also develop a universal system for polymer drilling fluids, trisulfonic drilling fluids, positive gel drilling fluids, mixed oil drilling fluids, weighted drilling fluids, and iron-chromium salt drilling fluids currently used in China. Processing technology and curing formula.

(4) Develop new technologies for drilling waste management system. The development of new technologies for the harmless and comprehensive utilization of waste drilling fluids is also one of the future trends, to achieve processing while drilling, solid-liquid separation, classified comprehensive management, comprehensive utilization to the greatest extent and energy saving and emission reduction. For example, the waste drilling fluid is cleaned and separated after the cuttings are purified, and part of the muddy water is reused for slurry preparation; the remaining muddy water is separated from solid-liquid dewatered sludge into cakes for recycling; the main pollutant indicators of the separated sewage treatment are used for site recovery. The cleaning water recovered after the liquid debris is separated is treated while drilling.
