| 摘 要： | 以往通过计算气井井口静压求取井底静压的诸多方法,由于未充分考虑随井深的增加,温度、压力的变化以及天然气中硫化氢、二氧化碳等酸性气体对偏差系数的影响,从而降低了其计算精度。文中根据温度、压力的变化范围,采用不同的天然气偏差系数计算模型,对含硫化氢高的酸性气体进行临界参数校正,以提高天然气偏差系数的计算精度,并在此基础上计算气井井底静压。通过实际资料验证,该方法能够比较精确地求取气井井底静压。 |
| 关 键 词： | 气井 井底静压 天然气偏差系数 计算方法 |

| Abstract: | The methods for calculating static pressure at bottom hole in the past do not take the varying temperature,pressure and gas components into consideration.According to the variation range of temperature and pressure,different computation models of gas deviation factor are applied to calibrate the critical parameter of acidic gas with high content of hydrogen sulfide,so as to improve the calculation accuracy of gas deviation factor.And based on the above-mentioned method,the static pressure at bottom hole is ... |
| Keywords: | gas well static pressure at bottom hole gas deviation factor calculation method |
