A novel intelligent sliding sleeve for shale oil and gas mining equipment

The principal purpose of this paper is to develop a new sliding sleeve which can overcome the inherent disadvantages of the present sliding sleeves. The working principle and structure of the device were explained. The novel energy source which adopted an accumulator was studied. Parametric optimization of the pipeline was developed by simulation study to avoid resonance. The key component, a new micro solenoid valve, was researched to control the sliding sleeve. The electromagnetic simulation was finished to research electromagnetic force. The compact structure which can satisfy the underground working environment was obtained. Design rationality of the novel intelligent sliding sleeve was validated by theory analysis and experiments. The novel intelligent sliding sleeve can meet the design requirements and perform well.
