Abstract: In view of the use and existing problems of high water cut hydraulic fluid for hydraulic support in Shendong mining area, the water quality of each mine in Shendong mining area was analyzed. The influence of mine water quality on hydraulic fluid was analyzed, including the influence of water hardness, the influence of impurities in water, the influence of sulfate ions and chloride ions, the influence of pH value, the influence of conductivity, and the comparison of different raw liquids and different hydraulic fluids. The matters needing attention in daily use and maintenance of hydraulic fluids were put forward. The corresponding hydraulic fluid should be scientifically selected and reasonably proportioned according to the mine water quality. The real-time monitoring of the hydraulic fluid should be paid attention to. The changes in the water quality, concentration, pH value and microbial situation of the hydraulic fluid should be monitored daily. The maintenance and management of the problems should be carried out in time according to the situation, so as to prevent equipment corrosion and ensure the working stability of the hydraulic system. It can provide reference for the selection, proportioning and maintenance of the high water-cut hydraulic fluid of the mine hydraulic support and ensure the safe and efficient production of the working face.

Abstract: The precipitation and deposition of wax has remained a major challenge that the oil industries is faced with during the production of waxy crude. This problem is simply an issue from the wellbore to the surface facilities. As a result of this, millions of dollars has been invested in remedial operations. In this research, a predictive model that uses thermodynamic relationship in predicting precipitation of wax has been developed. K-values for the solid-liquid equilibrium is described using solubility parameter, melting point temperature, enthalpy of fusion, and the molar volume for the components. The weight fraction was used to describe the wax mixture. Experimental data from three oil mixtures were used in comparing the model predicted wax appearance temperature (WAT). For oil mixA, the experimental value is 294.15K; Pauly et al predicted 302.15K while this work predicted 301.21K. For oil mixB, the experimental value is 300.15K; Pauly et al predicted 310.15K while this work predicted 308.91K. For oil mixC, the experimental value is 298.15K; Pauly et al predicted 302.15K while this work predicted 300.38K. The obtained results from this research confirmed the capability of the model in predicting Wax Appearance Temperature. A more conservative value for the WAT was predicted which is an improvement.
