Abstract


In an increasingly competitive economy and society, the important energy sources of oil as an economic development has attracted widespread attention, and exploitation of oil tools and techniques are also underway with the improvement and enhancement of high-speed. The current state-of-the-art playing in the domestic and international oil exploration cluster wells, directional well drilling technology using screw drill, single screw downhole motor as the main tool, the performance of a direct impact on the service life and efficiency of engineering, improved the single screw motor performance on practical engineering and even economic development of great significance. Traditional screw motor performance improvement is primarily for modifications of the cycloidal type line, the parting line of the screw motor improvement and design effective design tool for improving the performance of the motor of the screw concerned significance. Problem with the theory based on the traditional screw motor design was the work of the following aspects: (1) In theory, known inside and outside the cycloid equation, single parameters inside and outside the cycloid equidistance line equation is obtained, and compared to the traditional two-parameter equation, but also to facilitate the discussion and research; (2) curve stitching technology curve data for the known two-dimensional, multi-segment analysis curve is not smooth convergence of location and the corresponding algorithm applied to the screw contour of the theoretical design smooth curve stitching; (3) to generate a smooth curve (stator or rotor curve) after stitching thereto intermeshing conjugate curve, and the corresponding engagement analysis; (4) to be able to draw the screw curve through computer programming. , and through the graphics zoom function to visually identify the location can not be a smooth transition, not smooth transition condition Fairing; plot the mutual engagement of the stator or rotor graphics generating corresponding rotor or stator data. Contour of the curve equation, theoretical research, and through curves such as stitching technology the existing screw motor profile shaped curve is not smooth convergence at improvements to enhance the quality of the the screw motor profile shape curve, improved given rotor meshing performance . These efforts will extend screw life in the future, to improve the efficiency of the screw drill has a practical significance. This article uses the C language software programming, design and development of a the screw motor profile shape part of the design tools. The software for the actual status of the screw processing market, achieve the smooth handling of the curve, the stator and rotor conversion functions, has some practical value.
