摘要: In the framework of German R&D programme CLEAN (CO2 Large-Scale Enhanced Gas Recovery in Altmark Natural Field), geological structure an area encompassing Altensalzwedel sub-field and its surrounding was analysed detail. A 3-D model developed that contains major formations their general lithology including natural gas reservoir (in Permian Rotliegend), immediate cap rock (Permian Zechstein) overburden. Based on this model, a steady-state thermal generated as part shared earth model. The parameterisation layers with properties is based laboratory well-log data. shows temperature changes dependence different conductivity. calculated surface heat flow high (>80 mW m−2) for most area, which accordance to measured flow. Temperature top Rotliegend variable ranging from 110 150 °C. quantification versus depth well laterally are valuable input data modelling dynamic processes CO2 injection within CLEAN.
