硫在高含H_2S天然气中溶解度的实验测定

Measurement of the solubility of sulfur in natural gas with a high H_2S content

硫的溶解度测定是高含H2S气田开采过程中首先要解决的基础问题之一。为此,利用静态法测定了元素硫在普光气田X井高含H2S天然气中的溶解度。实验结果表明:在温度336.2～396.6 K、压力10.0～55.2 MPa下,元素硫的溶解度介于0.008 3～2.067 2 g/cm3;随温度和压力的增加,硫的溶解度增大,而高压(大于30 MPa)下增加的幅度较之低压下更加明显。该研究结果为普光气田的开发提供了重要的基础数据和技术支持。

The measurement of the solubility of element sulfur is one of the basic problems to be first solved in the development of high-H2S gas fields.In this case study,the static method was used to measure the solubility of the element S of X-well in the Puguang Gas Field with a high H2S content.The experimental results show that under the conditions with the temperature of 336.2-396.6 K and the pressure of 10.0-55.2 MPa,the solubility of the element S is 0.0083-2.0672 g/cm3.When both temperature and pressure increase,the solubility of the element S also increases and its increasing degree is more remarkable under higher pressure(>30 MPa) than that under lower pressure.This study provides important basic data and technical support for the development of the Puguang Gas Field.
