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.

The invention belongs to the technical field of aero-engine ground test equipment, and particularly discloses an integrated device with multi-type positioning and environment simulation functions. The tool comprises a supporting structure, a positioning structure and a box body structure. The supporting structure is a rigid framework formed by longitudinally and transversely welded rib plates, and an outer partition plate integrated with a multifunctional connector is fixed to one side of the supporting structure. The positioning structure is installed on the rib plate in a modularized mode through the replaceable installation sleeve and comprises at least two horizontally-adjustable positioning assemblies and one vertically-adjustable positioning assembly, the positioning requirements of aviation products of different models can be rapidly met by replacing the installation sleeve, and the positioning pin can freely move in the axial direction to compensate thermal expansion. The box body structure comprises side plates and a top plate and can be rapidly disassembled and assembled with the supporting structure, when an environment test is needed, the box body structure and the supporting structure jointly define a heat-preservation and sealed simulation environment cavity, and lubrication, sensing and temperature control gas conveying is conducted through reserved connectors in the outer partition plate. The universal positioning function and the integrated environment simulation function are highly integrated, the technical problems that an existing tool is single in function, inconvenient to switch and complex in simulation environment construction are solved, the test efficiency is remarkably improved, and the table building cost is reduced.

The application discloses a kind of variable curvature variable cross-section orthogonal grid composite component autoclave forming method, the digital model of variable curvature variable cross-section orthogonal grid composite component to be formed is divided into through grid assembly, non-through grid assembly and reinforcing layer assembly;And design corresponding mold laying tooling, mold laying is carried out, then respectively pre-compaction is carried out again assembly co-solidification.The application is formed by using "soft mold+expansion silica gel" auxiliary autoclave forming, adaptive variable curvature variable cross-section orthogonal grid composite component, and the forming mode avoids the phenomena such as fiber accumulation, fiber wrinkle, fiber fracture in grid intersection area, while reducing overpressure or insufficient pressure phenomenon, improve component strength;And the forming mode manufacturing process is simple, combination between different molds is convenient, easy to demould, greatly improve production efficiency, with good application value and popularization prospect.
