Inclusion Control

The hot metal fed converter in Panzhihua Steel Company is characterized by high sulfur content of 0.085% and high phosphorus content of 0.133%. Under this condition, some technologies like control of sulfur and T[O] content, ladle slag optimization, calcium treatment and protective casting were used in practice, and the desired result of T[O] as low as 0.0014% and sulfur content of 0.0023%was achieved, which met the cleanness requirements by anti-HIC X65 tube steel. With the help of inclusion control technology, grade of inclusions in as-cast steel was less than 0.5. In addition, total amount of inclusions was only 0.0044% which dispersed in slab in form of small spherical particle.

High-content H2S gas reservoirs are important for natural gas extraction. However, the precipitation and deposition of elemental sulfur in high-sulfur-content gas reservoirs eventually lead to porosity and permeability damage, resulting in the low well productivity. Therefore, it is worth developing an accurate production prediction model considering sulfur deposition for fractured horizontal wells. In this study, based on the partition model and transient percolation theory, a novel numerical model considering the damage of sulfur deposition with pressure change on reservoir porosity and permeability was first developed to predict the production from fractured horizontal wells in high-sulfur-content gas reservoirs. Then, it was validated by actual field data from a high-sulfur-content gas reservoir. After that, the influence of sulfur deposition on the production of fractured horizontal wells was revealed through theoretical calculations, and the effects of hydraulic fracture parameters on production were analyzed. The results show that elemental sulfur gradually deposits in the reservoir pores as the reservoir pressure decreases and the production time increases, which eventually leads to permeability damage and reduces reservoir productivity; this negative impact gradually increases over time. It is also shown that the production of fractured horizontal wells increases with an increase in the half-length, fracture conductivity, and fracture number. Compared with the fracture half-length, the fracture conductivity and fracture number have a greater influence on the production of a single well. The model can handle the influence of nonlinear parameters caused by sulfur deposition, which allows accurate calculations and provides guidance for the development of fractured horizontal wells in gas reservoirs with high sulfur content.
