High-efficient instant slurry powder and preparation method thereof

Abstract

The invention discloses a high-efficient instant slurry powder and a preparation method thereof; the high-efficient instant slurry powder is prepared from, by weight, 70-85 parts of tackifier, 10 parts of filtrate reducer and 5-15 parts of sediment accelerating agent; the tackifier can completely dissolve within a short time, and reach high viscosity under the condition of low mixing amount, thus the slurry wiredrawing state is good; the filtrate reducer can lighten the water penetration effect, obviously reduce the water loss of the slurry, and play very good stabilizing function of peripheral stratum; the sediment accelerating agent can remove sand and purify the slurry, so as to avoid secondary hole cleaning, control the sand content in the slurry, and reduce the wear of a drill bit by too much gravels; the recycling time of slurry is improved to 8 times, thus the economic cost is saved; the high-efficient instant slurry powder can be widely applied to powder sand layer, clay layer, water-sensitive stratum and other multiple geological conditions; the high-efficient instant slurry powder can protect the well wall for 48 hours without collapse in use.

Description

technical field [0001] The invention relates to a pile foundation wall protection mud material, in particular to a high-efficiency instant mud powder and a preparation method thereof. Background technique [0002] In the ever-growing infrastructure construction such as railways and subways, in order to ensure high-quality and low-risk construction of a large number of new projects, rotary drilling construction technology is widely used due to its technical advantages such as high construction safety, low environmental impact and high construction quality. use. During the construction of rotary drilling rigs, static mud protection walls are generally used, and most of them are made of bentonite or a single thickening component. At the technical level, there are many manual labor required for mud preparation, and the amount of discarded slurry is large. If the discarded slurry is not treated, it will easily cause secondary pollution. , The cost of discarded pulp treatment is ...

AI Technical Summary

Problems solved by technology

[0003] At present, most polymer muds used in domestic drilling have the problems of high water loss, low viscosity, and general wall protection effect, and there are still defects in recycling and use in complex geological conditions.

These are easy to cause more labor, large amount of discarded pulp, and high cost

CN105482789A discloses a method for preparing a new type of drilling mud. The mud prepared by this method contains bentonite, which enhances the water retention and wall protection of the mud. Abandon the traditional bentonite component in the mud preparation, and still can reach the product of same retaining wall effect; Disclose a kind of preparation method of geotechnical drilling engineering polymer type solid-free mud in CN102994060A, this mud product is only for In loose sand and weathered and broken rock formations, the applicable geological conditions are single, and the effect of mud recycling is not mentioned; CN104312553A discloses a preparation method of a drilling mud treatment agent. The mud product has a single component and its function is limited to The anti-collapse protection wall of mudstone has not been improved in terms of environmental protection, recycling and application to various geological conditions

These products only focus on the improvement of a certain performance of the mud, and cannot fully meet the requirements of the mud performance in the rotary drilling construction of various formations
