中文摘要	建立了沙漠峰双井式增强型热储的概念模型,并利用TOUGH2求解了模型。结果表明,利用双井系统开采沙漠峰热储是可行的,系统的流体循环量为30 kg/s,30年内的产热功率和产电功率分别为18.90 MW和3.42 MW左右,储层水流阻抗最大为0.095 MPa/(kg/s);在0.7~17.30年间储层温度和压强逐渐降低,水流阻抗逐渐增大,系统只产出液态水,而17.30~30年间储层温度、压强、水流阻抗基本保持不变,生产井井口附近液态水不断汽化,系统产出液态水和蒸汽的混合物,且气体产量逐渐增大。
英文摘要	A conceptual model for two-vertical wells enhanced geothermal reservoir at Desert Peak geothermal field was established, which was solved with TOUGH2. Results show that it′s feasible to exploit geothermal energy at the deep Desert Peak with two-vertical wells system. The system with a circulating fluid mass rate of 30 kg/s, has a thermal production power and electric production power, respectively, around 18.90 MW and 3.42 MW within 30 years, with a maximum water flow impedance up to 0.095 MPa/(kg/s). In the first 0.7~17.30 years, the temperature and pressure in the reservoir will decrease gradually and water flow impedance will increase gradually, resulting in the system only producing liquid water. While in the later 17.30~30 years, due to the reservoir temperature, pressure and flow impedance basically staying unchanged, liquid water close to production well mouse will continue to vaporize resulting in the system producing a mixture of liquid and gas, with gas output at an increasing rate.
