摘要

摘要: 普光气田高含H₂S天然气中的单质硫含量及临界析出压力是研究硫沉积问题首先要获取的两项关键参数，为此，基于气相色谱定量测定方法（外标标准曲线法），利用从普光104-1井取得的井下气样、DMDS-DMA高效溶硫剂及气相色谱-质谱联用仪等样品和仪器，首次测定出普光气田高含H₂S天然气中的硫含量为0.78 g/m³（每标准立方米气样中的硫含量），处于未饱和状态；进一步结合测定的不同压力下气样中硫的饱和含量变化曲线确定出临界析出压力为30.5 MPa；对比气田目前地层压力认为地层中尚未发生硫析出和沉积现象。

Abstract: The actual content and critical precipitation pressure of elemental sulfur in sour gas with a high H₂S content are regarded as two key parameters for studying sulfur deposition problems in the Puguang Gas Field. These two parameters have been quantitatively assessed using GC-MS, DMDS-DMA sulfur solvent and downhole gas samples from well 104-1 in the Puguang Gas Field. The experimental results showed that the sour gas in the Puguang Gas Field is unsaturated with an elemental sulfur content of 0.78 g/m³ at initial conditions. The critical precipitation pressure of sulfur in sour gas is 30.5 MPa, which means sulfur deposition has not yet occurred in a reservoir where a pressure of 35 MPa is greater than the critical precipitation pressure.
