The software "optimal design of production system for mechanical production wells" is developed to solve the important technical and economic problem of rational production of oil wells. The system mainly includes the optimization design software of electric pump well, pumping unit well, sucker pump well, mixed rod string well, screw pump well and so on. The development, application, improvement and perfection of the system have gone through a long process, pouring the efforts of software developers for more than ten years, and at the same time condensing the wisdom and experience of the relevant experts of the oil production engineering system as well as the vast number of field application personnel. It should be said that it is a more mature system. Expert comments on Science and Technology Identification of the system: it has reached the leading position in China. Level. In recent years, combined with the problems in the field application, the software has been greatly improved.

      At present, the software "optimized design of electric submersible pump well production system" (more than 100 well times) has been perfected and widely applied by this software, and good results have been obtained. At the same time, the software "optimal design of screw pump well production system" has been successfully developed, and the results of design and prediction are very close to the actual test results. The "help" system of the software has been perfected, so that the function is quite complete (including the optimization design of the main mechanical oil recovery modes in China), the maturity is relatively high, and it is more suitable for the field application of the optimization design system of mechanical production wells. The system has been popularized and applied in a wide range, and good application results have been obtained. Great economic benefits. The development and application of the system provide an effective means to improve the design level of oil production process and realize the transformation of oil well management from experience type to scientific management type.

      The purpose of the optimization design is to select the swabbing equipment and parameters suitable for the characteristics of the oil well and to carry out the operation according to the selected scheme in order to give full play to the potential of the reservoir and the swabbing equipment so that the oil well can be safely produced under the conditions of high production and high efficiency.

       For rod pump wells (pumping unit well, screw pump well, hydraulic feedback heavy pump well), it is mainly used to determine pump diameter (pump type), down pump depth, stroke, tubing and rod string combination, pumping unit type (ground drive unit model), The motor power and so on, and carry on the forecast to the effect after the implementation; For electric pump wells, it is mainly used to select pump type, vane guide wheel series, motor, cable, control panel, transformer, oil nozzles and the required voltage on the ground.
