| 摘 要： | 异常高压气藏偏差因子的各种计算方法结果相差较大，针对克拉2异常高压气藏，对比研究了７种常用的天然气偏差因子计算方法，并应用灰关联法对这几种方法进行了优选。结果表明，对于克拉2异常高压气藏而言，可选用张国东法、HTP法或BB法计算偏差因子；特别是在8≤ppr＜15、1.05≤Tpr＜3.0时，李相方法是计算该气藏偏差因子的最佳选择。研究结果可为异常高压气藏开发提供一定的参考。

| Abstract: | Various calculation methods for the deviation factor of abnormally pressured gas reservoirs will obtain results with big difference. Aiming at this abnormally pressured gas reservoir in the Kela 2 gas field, this study compared seven common calculation methods for the deviation factor and optimized these methods by using the gray correlative method. The results showed that for this abnormally pressured gas reservoir, the Zhang Guodong method, the HTP method and BB method can be applied to calculate the deviation factor; especially for the gas reservoir under the condition of 8≤ppr＜15 and 1.05≤Tpr＜3.0, the Li Xiangfang method is the best choice for calculating its deviation factor. The research results can offer certain reference to the development of abnormally pressured gas reservoirs. |
