The Kinetics Mechanism Analysis of Sulfur Depositions in High Sulfur Content Gas Reservoirs
Abstract:
The origin of particles which lead to reservoir damage in oil industry mainly includes internal generation and external invasion. The particles generated in reservoir include clays, mineral particles, deposits and particles which are separated out in physical and chemical effects. Particles of external invasion include invasions in the process of drillings and fracturing operations, particles in work-over operation and completion fluid operation, or debris which are carried by injection fluid (water, chemicals, etc.). The force of the particles has affected the seepage law in high sulfur gas reservoir. By analysis of the particle migration, sedimentary characteristics, and the force situation of sulfur particles, we will discuss dynamical mechanisms of sulfur deposition.
