摘要/Abstract

摘要： 准确计算天然气多组分系统的偏差系数对于气藏储量评价、储气库和地面设备设计至关重要，常通过实验测定、用拟临界压力和温度通过查询Standing-Katz图版、状态方程和经验公式计算确定。由于气体温压条件的变化、硫化氢等非烃组分的存在，使得实验测定和状态方程法昂贵、复杂。同时，针对储层深度超过5 000 m、非烃组分含量最高达20%的高含硫天然气偏差系数计算，传统的DAK、DPR等经验公式能否适用尚不明确。利用元坝气田长兴组气藏的999个深层高含硫天然气偏差系数实测数据点进行回归，得到通过拟对比压力和拟对比温度计算偏差系数的预测模型。与DAK、DPR、Beggs-Brill、Papay经验公式及LXF解析模型等的对比表明，该模型预测结果计算精度更高，和实测值的相关系数超99%。模型可用于确定压力0~70 MPa、温度30~150 ℃的超深层高含硫天然气偏差系数，利用该模型绘制拟对比温度1.02≤T_pr≤2.20和拟对比压力0.1≤P_pr≤20.0内偏差系数随拟对比压力变化的关系图，可为超深层高含硫气藏的高效开发提供有益借鉴。

Abstract: Accurate calculation of the deviation coefficient of natural gas multi-component system is very important for gas reservoir reserve evaluation, gas storage and surface equipment design. It is usually determined by experimental measurement, pseudo-critical pressure and temperature by querying the Standing-Katz chart, equation of state and empirical formula. Experimental determination and equation of state are expensive and complicated due to the variation of temperature and pressure conditions of gas and the existence of non-hydrocarbon components such as hydrogen sulfide. At the same time, it is not clear whether traditional empirical formulas such as DAK, DPR can be applied to calculation of the deviation coefficient of high sulfur gas with reservoir depth of more than 5 000 meters and non-hydrocarbon component content of 20%. Based on the regression of 999 data points of deviation coefficient of deep gas with high sulfur content measured in Changxing Formation gas reservoir of Yuanba Gas Field, a prediction model of deviation coefficient Z is obtained by pseudo-contrast pressure and pseudo-contrast temperature. The correlation coefficients of the proposed model with DAK, DPR, Beggs-Brill, Papay empirical formula and LXF analytical model are compared. The results show that the correlation coefficient between the z-factor model and the measured values is over 99%, and the calculation accuracy is obviously better than the traditional empirical formula method. The model presented in this paper can be used to determine the deviation coefficient of ultra-deep gas with high sulfur content in the pressure range of 0~70 MPa and temperature range of 30~150 ℃. The model is used to draw the relationship diagram of Z value with pseudo-contrast pressure in the range of pseudo-contrast temperature 1.02≤T_pr≤2.20 and pseudocontrast pressure 0.1≤P_pr≤20.0. It provides a useful reference for the efficient development of ultra-deep gas reservoirs with high sulfur content.
