Ay and two-way coupling strategy.two.three. Reservoir Model two.3. Reservoir Model Figure 44 shows a schematic in the reservoir model. The cylindrical coordinated sysFigure shows a schematic from the reservoir model. The cylindrical coordinated technique was utilised to model the gas hydrate layer with overburden and underburden. Due to the tem was used to model the gas hydrate layer with overburden and underburden. Due to the fact normally low permeability of your system as well as the relative abundance of clays, properly spacing on the usually low permeability with the system and also the relative abundance of clays, effectively was restricted to 500 m, resulting within the 250 m outer radius with the cylindrical method [23]. spacing was restricted to 500 m, resulting within the 250 m outer radius of the cylindrical sysThe overburden thickness was 140 m, as well as the HBS thickness was 13 m. Underburden tem [23]. The overburden thickness was 140 m, along with the HBS thickness was 13 m. Underthickness was 300 m. In an effort to raise numerical convergence stability, discretization burden thickness was 300 m. So that you can improve numerical convergence stability, disalong the r-direction was not uniform, alternatively growing Nimbolide In Vitro logarithmically from the Tianeptine sodium salt supplier center cretization along the r-direction was not uniform, instead growing logarithmically from on the technique. The z-direction grid size was 10 m for the overburden and underburden, the center of the system. The z-direction grid size was ten m for the overburden and unand 0.1 m for the HBS. For that reason, the system was discretized into 160 1 90 = 14,400 derburden, and 0.1 m for the HBS. Consequently, the technique was discretized into 160 1 90 gridblocks. The vertical production well was located at the center from the cylindrical model, Appl. Sci. 2021, 11, x FOR PEER Critique 5 of 15 = 14,400 gridblocks. The vertical production well was located at the center on the cylindriand the radius with the properly was 0.1 m. The geomechanical grid method was precisely the same because the cal model, plus the radius of the well was 0.1 m. The geomechanical grid technique was the reservoir grid method. very same because the reservoir grid system.Figure four. Cylindrical model made use of within the simulation. Figure four. Cylindrical model made use of in the simulation.Numerous preceding simulation studies have utilized a lot of assumptions, for example the simple reservoir model, correlation relative permeability curve model and permeability permeability model [12,18,23,25,302]. Accordingly, the reservoir model of this study was constructed by using realistic field information, as shown in Figure 5 and Table 1. This model employed the logging data of UBGH2-6, as well as the HBS of this model is composed of 14 sand layers and 13 shale layers [33]. The sand porosity is 45 , and mud porosity is 67 . The array of hydrate sat-Appl. Sci. 2021, 11,Figure 4. Cylindrical model made use of in the simulation.five ofVarious prior simulation research have utilized several assumptions, such as the easy reservoir model, correlation relative permeability curve model and permeability model [12,18,23,25,302]. Accordingly, the reservoir model of this study was constructed model [12,18,23,25,302]. Accordingly, the reservoir model of this study was constructed by using realistic field data, as shown in Figure and Table 1. This model utilised the logging by utilizing realistic field data, as shown in Figure 55 and Table 1. This model employed the logging data of UBGH2-6, as well as the HBS of this model is composed of 14 sand layers and 13 shale information of UBGH2-6, plus the HBS of this model is composed of 14 sand laye.
