In the process of production logging interpretation, a water cut is one of the key factors to obtain the oil phase content in the oil well. In order to measure the water cut of the horizontal oil–water two-phase flow with low yield, the response characteristics of the combined capacitance sensor (CCS) are investigated under different flow patterns. Firstly, the measuring principles of coaxial, cylindrical, and CCS are introduced in detail. Then, according to the different flow pattern conditions of the horizontal oil–water two-phase flow, the response characteristics of the CCS are simulated and analyzed using the finite element method. Additionally, compared with the other two sensors, the advantages of the CCS are verified. Finally, the temperature and pressure calibration experiments are carried out on the CCS. The horizontal oil–water two-phase flow patterns in a low yield liquid level are divided in detail with a high-speed camera. Dynamic experiments are carried out in a horizontal pipe with an inner diameter of 125 mm on the horizontal oil–water two-phase flow experimental equipment. The simulation and experimental results show that the CCS has good response characteristics under different working conditions.

To address the issues of battery dependence, energy consumption, and energy management imbalance in industrial wireless sensor networks (IWSNs), this study proposes a green and energy-saving multiobjective clustering scheme to improve network efficiency and reduce environmental pollution. Given that conventional methods struggle to effectively optimize IWSN clustering, this article specifically designs a novel multiobjective clustering model. During the optimization process, this model comprehensively considers four key performance indicators: 1) total remaining energy, 2) average network delay; 3) average network packet loss rate; and 4) average distance from cluster heads (CHs) to the base station (BS), achieving holistic optimization of network performance. To further enhance clustering efficiency and network stability, this article also introduces a green energy-saving scheme based on the chaotic elite clone elephant herding optimization algorithm (i.e., CECEHO-GCS). This scheme ingeniously incorporates chaos operators in the initialization stage to enrich solution diversity and introduces clone and elite operators in the evolution stage, aiming to retain superior solutions and significantly enhance the algorithm’s search capabilities. Through comparative experiments with four existing advanced clustering schemes: 1) LEACH-C; 2) LEACH-R; 3) ESCVAD; and 4) ARSH-FATI-CHS, the model and the algorithm proposed in this article, CECEHO-GCS, demonstrate significant advantages in improving network energy efficiency and service quality. Specifically, CECEHO-GCS has achieved an improvement of at least 19.27% in network lifespan and at least 16.89% in data throughput, opening up new avenues for green energy conservation and sustainable development in IWSNs.
