“…The long-distance wireless communication network is the channel to realize the transmission of data information between the server and the wellhead surface controller, mainly using VPDN technology [12].. Install a customized SIM card that supports VPDN technology on the industrial wireless router inside the electric control cabinet, and build a virtual dedicated channel on the public network that is free from external interference, and can safely access the internal data resources of the enterprise network [13]. The wireless communication network connects the ground controller with the data center server (internal network of the oil field), and the host computer client uses the user name and password to log in and access the server, ensuring the safety and reliability of the remote transmission data.…”

A remote wireless intelligent layered water injection technolo-gy is proposed to address the problems of traditional layered water in-jection well testing in oil fields, such as the inability to achieve continu-ous dynamic monitoring of injection parameters, high failure rate, and low success rate of testing and commissioning. The technology consists of a host computer client, a server, a surface controller, and an under-ground intelligent water distributor. The underground intelligent water distributor takes the injected water as the carrier, and uses the fluctua-tion of the water injection pressure in the tubing for signal transmission to realize two-way communication between the ground controller and the downhole intelligent water distributor. The underground intelligent water distributor integrates high-precision pressure gauges, controllable water nozzles, and calculation and control modules to form an intelli-gent control system, realizing the reception of ground down transmitted commands or data, the calculation and control of water injection flow rate of water nozzles, and the storage and upload of underground data. Remote wireless intelligent layered water injection technology has been applied in 43 wells, with a success rate of 100%. The maximum depth is 3897m, and the maximum wellbore inclination is 56.07°. This tech-nology realizes remote control of water injection wells, intelligent au-tomatic measurement and adjustment, real-time data monitoring, and automatic early warning functions, laying a foundation for the con-struction of “Digital Intelligence” oilfield.

“…3). In both closed and open systems, the Joule cycle is more efficient than the Otto cycle for small values of CR [48,47,49]. Dib et al [48,49] also studied the thermodynamics of different compression/expansion cycles with a LP and showed that a Joule cycle is more adapted for a LP gas compression for energy storage.…”

Compressed air energy storage systems (CAES) have demonstrated the potential for the energy storage of power plants. One of the key factors to improve the efficiency of CAES is the efficient thermal management to achieve near isothermal air compression/expansion processes. This paper presents a review on the Liquid Piston (LP) technology for CAES as a timely documentary on this topic with rapidly growing interests. Various aspects are discussed including the state-of-the-art on LP projects all over the world and the trend of development, the coupled fluid flow and heat transfer during the compression/expansion operations, and different actions proposed and implemented to enhance the heat transfer inside the piston column.It has been found that LP is a promising concept for isothermal CAES. However, the complex and transient fluid flow and heat transfer behaviors inside the LP are difficult to characterize and master. To enhance the heat transfer and increase the efficiency of the compression/expansion processes many approaches have been tested including liquid spray, wire mesh, porous media, optimal trajectory, hollow spheres and optimal geometry of the piston column. Numerous Nusselt number's empirical correlations have also been proposed to estimate the

Isothermal compression is the state‐of‐the‐art in compressed air energy storage (CAES) technology. The study of cyclic pressurization unit in isothermal CAES is carried out in this paper. The unit can continuously compress air utilizing double vessels operating alternately. In each vessel, the large heat capacity of water and spray cooling is applied to establish a conducive environment for the air achieving the effect of efficient near‐isothermal compression. The operating mode of the cyclic pressurization unit is divided into sliding‐pressure operation and constant‐pressure operation according to the pressure of its outlet. By adopting the characteristic curves of pump, the dynamic model is built for the unit in this paper. Further, the differences between the cyclic pressurization unit in isentropic process and in variable‐speed process are quantified and compared in four different cases. In isentropic process, the energy‐saving ratio and exergy efficiency of the unit are expected to reach 20.4% and 95.0%, respectively. In variable‐speed process, the energy‐saving ratio and efficiency of the unit can achieve 7.3% and 73.4%, respectively. This gap is mainly determined by the off‐design performance of the pump. Moreover, the vessel volume should be no less than 3 m3 and 5 m3 when there is spraying and when there is no spraying. Furthermore, spraying favors the improvement of the worsened compression performance caused by the change of design parameters. The energy‐saving ratio can be improved via spraying by 1.3% to 11.0% and 1.8% to 25.6% in the isentropic and variable‐speed processes, respectively. Meanwhile, the exergy efficiency can be increased by 1.5% to 9.4% in the isentropic process and 1.4% to 8.4% in the variable‐speed by spraying.
