摘要
高含硫气体在一定压力和温度条件下能溶解于地层水中。对于存在边水或底水的高含硫气藏,随着开发的逐步进行,溶解在水中的酸性气体会慢慢释放出来,使得气藏开发过程中组分和组成不断发生变化,从而对开发井的生产管理和控制以及地面集输的脱硫能力提出新的任务和要求。为此,建立高含硫气体在地层水中溶解度测试流程,测定了川东北罗家寨飞仙关组地层温度条件下高含硫气体从原始地层压力不断降压过程中高含硫气体在地层水中溶解度。该溶解度测定方法的建立,为研究罗家寨高含硫气藏开发过程中组分和组成的变化规律奠定了良好的基础,对于指导高含硫气藏的安全合理开发具有重要意义。
High sulfur content gas is soluble in formation water under certain pressure and temperature conditions.As the development of gas reservoirs with edge water or bottom water and high sulfur content,the sour gas dissolved in water can release slowly and lead to composition change,thus posing a new task and requirement to the production management and control of development wells and the sulfur removal capability of surface gathering and transportation system.Therefore,a test process of solubility of high sulfur content gas in formation water is established to measure the solubility under formation temperature in the process of pressure reducing from initial formation pressure in Feixianguan Formation of Luojiazai in the northeast of Sichuan.This measuring method of solubility facilitates the composition study during the development of high sulfur content gas reservoirs in Luojiazai and is of great significance to safe and rational development of such reservoirs.
