摘要
高含硫气藏开发过程中,伴有元素硫的析出沉积、气相组成变化和沉积的硫堆积在孔隙喉道污染地层等特殊现象,其中硫沉积是影响高含硫气藏开发的重要原因。在分析硫微粒在多孔介质中的运移和滞留的基础上,引入宏观气固流体力学中描述颗粒在气体中运移的流体力学模型,建立了硫微粒在多孔介质中的运移沉积模型。该模型考虑了硫微粒的产生、在气流中的悬浮运移以及在孔隙表面的沉淀、吸附等。
A high sulfur gas field is generally associated with sulfur precipitation and deposition, change of gas phase composition and sulfur accumulation in pore throat to damage to the reservoir during its development, among which sulfur deposit is a main factor affecting such a gas reservoir development. Based on the analysis of the sulfur particles flow and precipitation in porous medium, this paper introduces the hydrokinetics model for description of particle flow in gas phase in the macroscopic gas-solid hydrokinetics theory, and develops the model for sulfur particle flow and deposition in porous medium. In this model many factors are considered, such as generation of sulfur particles, the suspending and flow in the gas phase as well as the precipitation and absorption in the pore surface.
