In this test, water was injected into injection well HDR-1. The depth of the injection well was about 2, 200m, and the maximum ternperature of the well was about 270 degC. The main fracture, which was extended along natural joints, was initiated from the bottom hole and a radius of the fracture was estimated to be about 500m from the acoustic emission observation. In this paper, the radius of the fracture, and the pressure, permeability and aperture distribution within the fracture was estimated by numerical simulation. The FEHM (Finite Element Heat and Mass transfer) code was used to estimate the radius of the growing fracture and a pressure distribution within the fracture. The Gangi bed-of-nails model was used to relate the fracture aperture to the fluid pressure. The permeability of the fracture was then calculated from the fracture aperture using Lomize's friction factor. A pressure history match between measured and calculated value was obtained. The simulation result shows that the radius of the fracture at the end of the experiment was about 500m, which agrees well with observations. The estimated apertures of the fracture at the vicinity of the well were 1.4mm and 2.6mm when the injection water rates were kept constant at 6kg/s and 20kg/s, respectively. In this simulation, three fitting parameters were used to match the pressure history. The sensitivities of three parameters on the simulation results were also examined.","PeriodicalId":22754,"journal":{"name":"The Mining and Materials Processing Institute of Japan","volume":"140 1","pages":"247-253"},"PeriodicalIF":0.0,"publicationDate":"1997-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88740391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The stress conditions of all 77 cases in this study were divided clearly into two groups by the direction of the maximum tensile stress in the central part of the core. In one of the groups the tensile stress is nearly in the direction of the core axis and in the other the tensile stress is nearly perpendicular to the core axis. Only 26 cases in the total 77 cases gave the stress conditions necessary for core disking. In these cases, the difference in the magnitude of the maximum tensile stress between in the central part and in the outer part of the core was small, which suggests that the stress conditions enable a crack initiated at the outer part of the core to penetrate through the entire core. These cases included the stress conditions where the far field minimum principal stress is not in the direction of the core axis. To produce a through crack in the core by tensile stress, the stress contour plane of the tensile stress must exist throughout the cross section of the core. Therefore, it is assumed that core disking occurs if the tensile stress whose upper and lower contour planes just touch each other reaches the tensile strength of the rock. This tensile stress, called the critical tensile stress in this study, is given by the minimum principal tensile stress among the maximum principal tensile stresses which are determined by searching the maximum value along the core axis for a set of the coordinates in the core cross section. Thus, we have proposed the following criterion on core disking:","PeriodicalId":22754,"journal":{"name":"The Mining and Materials Processing Institute of Japan","volume":"3 1","pages":"155-161"},"PeriodicalIF":0.0,"publicationDate":"1997-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76477303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
