[Abstract]:Intelligent well technology has outstanding advantages in improving reservoir management, improving oil and gas recovery, and optimizing production efficiency. It can improve the present situation of "three high and two low" oil production and the increasing reality of low permeability oil fields in China. Foreign intelligent well technology has formed a relatively complete system, but the domestic research on intelligent well technology is still in its infancy. Therefore, this paper attempts to study the method of interwell fluid control in intelligent wells. In this paper, the structure and working principle of InCharge all-electric intelligent well system are studied, and the structure and working principle of IPR sliding sleeve valve are deeply analyzed, which provides a reference for designing the intelligent well system suitable for small hole oil well in our country. According to the design requirements of intelligent well system, an intelligent well system is designed, which is applied to 7 'borehole, 3 formation direct hydraulic driving optical fiber measurement. The overall scheme of the system and the installation structure of downhole string are completed. The design details of power supply system and hydraulic system process, automatic measurement and control, PLC monitoring system, control logic, installation and equipment layout are given. The design scheme of the intelligent well system based on direct hydraulic driving fiber optic measurement is verified by the simulation of the downhole pipe string, and the rationality of the design is verified, and the design requirements are basically met. In view of the fact that the domestic oil wells are 5-l / 2 VJ, with the majority of boreholes, there are more hydraulic pipelines driven by direct hydraulic power, which occupy the space of effective utilization of boreholes, and have poor penetration under the tubing string. An intelligent interlayer fluid control system for 5 'borehole and 30 formation is designed in this paper. The structure of all-electric 1CV, the actuating mechanism of all-electric ICVit, the intelligent valve controller, the measuring and processing circuit of downhole temperature and pressure signal, the transmission medium, the transmission circuit and so on are designed and completed. A prototype model of valve drive and control system was made and some functional tests were carried out. The test results show that the model prototype can realize the positioning opening / closing control of the valve, basically reaching the design H standard. The research work and the scheme design work can provide a useful reference for the development of intelligent well system with independent intellectual property rights in China.
