Abstract

The invention discloses a low fluorescent lubricating agent for drilling fluid and a method for preparing the low fluorescent lubricating agent. The low fluorescent lubricating agent is prepared from the following materials by weight percent: 30%-70% of swill-cooked dirty oil, 10%-30% of natural fatty acid, 10%-30% of vegetable oil, 1%-10% of oleic acid, 1%-3% of dodecylbenzene sulfonic acid and 1%-3% of polyvinyl alcohol. The method for preparing the low fluorescent lubricating agent comprises the following steps: accurately weighing the materials in a ratio, then putting the materials into a reactor, heating to 40-60 DEG C and stirring for 1-2hours at constant temperature. The method is simple in polymerization process and is suitable for industrial production; the low fluorescent lubricating agent for the drilling fluid is high in performance cost ratio, small in dosage and excellent in lubricating performance, is suitable for various water-base mud systems; and the low fluorescent lubricating agent is fluorescent-free and pollution-free, does not interfere geological logging work, dose not foam, dose not stick sieves, dose not influence other drilling fluid performances and dose not increase viscosity and water loss.

Description

technical field [0001] The invention relates to a lubricant for drilling fluid prepared from waste oil and a preparation method thereof. Background technique [0002] In oil drilling and well completion operations, various frictions will inevitably occur when the drill bit drills in and out. Friction will lead to excessive torque of the drill bit, and even cause accidents such as well wall instability and drill sticking. In severe cases, it will fail to drill to the target layer or even lead to the scrapping of the well, resulting in huge economic losses. Therefore, it is often necessary to add lubricants to the drilling fluid during drilling to reduce frictional resistance during drilling, improve drilling speed and reduce downhole accidents. At present, lubricants for drilling fluids can be divided into two categories: liquid lubricants and solid lubricants according to their physical form. Among them, the main raw materials of liquid lubricants are mostly organic compou...
