2results about How to "Optimize design parameters" patented technology

The application discloses a shale oil horizontal well microseismic fracture parameter interpretation prediction method, and steps are as follows: step (1), microseismic fracture parameter interpretation prediction data preparation, determining the principle of parameter screening, and collecting the data of the screened parameters; step (2), data preprocessing; step (3), fracture parameter influence factor screening; step (4), regression prediction model construction; step (5), regression prediction model verification and evaluation; and step (6), application of the regression prediction model. The application has the following beneficial effects: 1. two modeling methods are used to establish a shale oil fracturing fracture parameter prediction model, and quantitative prediction of microseismic fracture parameters is realized; 2. high accuracy; 3. as a basis for shale oil horizontal well design, the application can optimize construction scale and design parameters, and also can provide a diagnosis method for fracturing construction, timely adjustment of construction parameters and improvement of fracturing reconstruction effect.

This utility model relates to the field of bearing runout torque detection technology, and more particularly to a composite bearing runout torque measuring fixture. A composite bearing runout torque measuring fixture includes: a mounting base, balance bars respectively disposed at both ends of the mounting base, a composite flange bearing disposed between the two balance bars, and a detection component disposed at the end of one of the balance bars. The composite flange bearing is disposed close to the mounting base, and the shaft hole of the mounting base, the outer diameter of the balance bars, and the inner hole of the composite flange bearing are coaxially arranged. This utility model provides a composite bearing runout torque measuring fixture with advantages such as accurate measurement results, small error, high measurement precision, good stability and robustness, convenient assembly and disassembly, and low cost.
