Problems solved by technology

[0003] Traditional mud will not solidify without air drying or treatment, and the solid content is low, more than 80% is water. Over time, the water will gradually lose, leaving a lot of space, which will lead to the collapse of important waterways or roads risk and therefore not suitable for filling this crevice space

Abstract

The invention relates to filling and curing slurry for horizontal directional drilling and a preparation method of the filling and curing slurry, and belongs to the technical field of filling slurry.The filling and curing slurry for horizontal directional drilling is composed of the following components in parts by weight: 20 parts of water; 11.3 to 13.3 parts of bentonite; 6.5 to 8.5 parts of cement; 55 to 61 parts of silt; 3 to 5 parts of nonionic cellulose; 0.05 to 0.15 part of a vinyl monomer multi-component copolymer; 0.04 to 0.06 part of a corrosion inhibitor; and 0.04 to 0.06 part of sodium polyacrylate. The invention further provides a preparation method of the filling and curing slurry for horizontal directional drilling. The filling and curing slurry for the horizontal directional drilling is low in viscosity, good in fluidity and small in shrinkage rate, gaps can be filled and compacted through the filling and curing slurry, and therefore the risk of collapse is avoided.

Description

technical field [0001] The invention belongs to the technical field of filling mud, and in particular relates to filling and solidifying mud for horizontal directional drilling and a preparation method thereof. Background technique [0002] With the maturity of directional drilling technology, domestic directional drilling is more and more widely used. The reaming diameter of the directional drilling construction is larger than that of the pipeline. After the pipeline is dragged back into place, there will be a large gap between the pipeline and the formation. Therefore, it is necessary to fill and solidify the mud to seal the gap. [0003] Traditional mud will not solidify without air drying and treatment, and the solid content is low, more than 80% is water. Over time, the water will gradually lose, leaving a lot of space, which will lead to the collapse of important waterways or roads risk and therefore not suitable for filling this crevice space. [0004] In view of t...
