Novel continuous production device for fluid loss additive for drilling fluid

Abstract

The invention discloses a novel continuous production device for a fluid loss additive for drilling fluid. The novel continuous production device comprises a cylinder body, wherein a processing cavityis arranged in the cylinder body; one end of the cylinder body is provided with a continuous feeding device; the continuous feeding device comprises an intermittent feeding chamber, a continuous feeding chamber, a first motor, a second motor and a second vacuum pump; a feeding port of the intermittent feeding chamber is provided with a first partition plate, and the first motor drives the first partition plate to close or open the feeding port; the second vacuum pump is used for vacuumizing the intermittent feeding chamber, and a second partition plate is arranged at the communication position of a discharging port of the intermittent feeding chamber and a feeding port of the continuous feeding chamber; the second motor drives the second partition plate to close or open the discharging port of the intermittent feeding chamber, and a discharging port of the continuous feeding chamber communicates with the processing cavity; and a grinding assembly is arranged in the processing cavity in the axial direction. With the novel continuous production device for the fluid loss additive for the drilling fluid, continuous production of vacuum drying and seamless butt joint with alcohol washing at the upstream are realized.

Description

technical field [0001] The invention relates to chemical production equipment, in particular to a novel continuous production device for fluid loss reducer for drilling fluid. Background technique [0002] The fluid loss reducer is an indispensable additive in the drilling fluid, which is used to adhere to the well wall to form an isolation layer during the drilling process to prevent the fluid loss of the drilling fluid. Most of the production steps of the fluid loss control agents in the prior art include dissolving, reacting, washing with alcohol, vacuum drying and grinding. Among them, dissolving and reacting can be carried out in a stirred tank, and washing with alcohol can be carried out in a reaction tower. Carry out, vacuum drying has a vacuum drier, and grinding has a pulverizer, as the application publication number is CN107828024A, and the name is called "Preparation Method of Polymer Fluid Loss Agent", and the application publication number is CN108130059A, and t...

Problems solved by technology

[0003] The disadvantage of the existing technology is that the alcohol washing of the reaction tower can be produced continuously, but the vacuum desiccant cannot be produced continuously due to the requirement of vacuum degree, which makes the alcohol washing and vacuum drying appear between the two processes. In order to avoid disconnection, a material storage device must be equipped, which has a negative impact on production
