This invention discloses a tool and method for constructing a horizontal wellbore through repeated volumetric fracturing. The tool includes a surface control device and a downhole main unit, with the surface control device located outside the downhole main unit. The downhole main unit includes a cylinder, with a top seat and a base connected to its top and bottom ends via upper and lower bearings, respectively. Both the top seat and the base are cylindrical. An electric motor is installed inside the base and connected to the surface control device and the lower bearing. A magnetic positioning device is installed inside the cylinder and connected to the surface control device. Several nozzles are provided on the sidewall of the cylinder, and each nozzle has a pressure-bearing, fracture-resistant outer wall matching its size. A connector for connecting to tubing is fixedly installed at the upper end of the top seat. Packers are installed on the outer sides of both the top seat and the base. This invention can reduce the amount of materials used in wellbore reconstruction and lower construction material costs.

This application relates to the field of fine chemicals, specifically disclosing an alicyclic aminosilane compound and its preparation method. The alicyclic aminosilane compound has the structural formula R1R2R3Si-NH-Cy-CH2-Cy-NH-SiR1R2R3; wherein R1, R2, and R3 are each independently selected from C1-C6 alkyl, C6-C10 aryl, or R1, R2, and their attached silicon atoms together form a cyclic silazane structure containing 2-5 silicon atoms; Cy represents a substituted or unsubstituted cyclohexyl group. The preparation method of this compound includes: reacting 4,4'-methylenebiscyclohexylamine or its salt with a silane compound in the presence of an inert gas and an organic solvent at a temperature between 0°C and the reflux temperature of the organic solvent; after the reaction, post-treatment yields the target product. The product structure of this application is novel, and the synthesis method is simple, filling the gaps in existing technologies for synthesizing alicyclic aminosilane compounds.
