Problems solved by technology

[0005] The above-mentioned traditional drilling waste treatment method buried the drilling fluid with a large amount of active ingredients together with the large particles, resulting in a certain amount of waste; at the same time, the traditional treatment method required a lot of post-maintenance work after drilling (for example: vegetation restoration, recultivation, etc.), and will permanently leave hidden dangers of environmental pollution

Abstract

The invention discloses a waste drilling fluid processing device which comprises a collection and separation system, a waste drilling fluid regeneration processing system, a rock debris (solid waste) processing system and a drilling fluid maintenance system, wherein the collection and separation system collects a waste drilling fluid from a solid control circulation device of a drilling platform during drilling and separates the liquid into solid-phase and liquid-phase components; a liquid phase of the collection and separation system is conveyed to the regeneration processing system through a first transmission system, and the processed liquid phase is conveyed to the drilling fluid maintenance system, so that on-site recycling is realized; a solid phase of the collection and separation system is conveyed to the rock debris processing system through a second transmission system and then is processed, and resource utilization is realized. Recycling of liquid-phase and solid-phase wastes caused by well drilling can be realized, so that the resource utilization rate is increased, the production cost is saved, well-site zero release is realized, and the environmental protection problem of a well site is solved fundamentally.

Description

technical field [0001] The invention relates to the technical field of drilling auxiliary equipment, in particular to a waste drilling fluid treatment device. Background technique [0002] Drilling fluid is a circulating fluid used for drilling, and it is a circulating flushing medium used in the hole during the drilling process. Drilling fluid has the functions of carrying and suspending cuttings in the wellbore, balancing formation pressure, cooling and lubricating drill bits and drilling tools, protecting well walls and oil and gas layers, and increasing drilling speed. It plays a very important role in the drilling process. [0003] Drilling waste fluid (mud) is a multiphase stable colloidal suspension system, which contains a variety of inorganic salts, organic treatment agents, polymers, surfactants and other substances, which contain oils, salts, drilling fluid additives and some soluble The heavy metal ions pollute the soil and water, affect the growth of animals an...
