Abstract:
The exploitation and utilization of geothermal energy is becoming the focus of new energy development in China. The national 13th Five-year Plan(2016-2020) for geothermal energy development and a series of safeguard measures will accelerate the development of geothermal industry. Oilfield enterprises with rich hydrothermal geothermal resources can use geothermal energy for crude oil gathering and transportation, space heating, oil tube washing, etc., replacing fuel oil, fuel gas and fuel coal. Based on the geological characteristics of geothermal energy in oilfields, the evaluation of geothermal resources can depend on the stochastic simulation, volumetric evaluation and analog method. According to the systematic evaluation of hydrothermal geothermal resources buried less than 4 km in 11 basins or blocks by the stochastic simulation and volumetric evaluation, the geothermal resources amount is 31 784.45×10
18J in China. Moreover, the geothermal water resources amount is 375 085.18×10
8m
3, and the recoverable geothermal resources amount is 47.68×10
18J/a. The characteristics of the geothermal resources of petroliferous basins in eastern China show high temperature, shallow burial depth, and low-cost development and utilization. Grading evaluation of geothermal resources can lay the foundation for the ordered and large-scale development and utilization of geothermal energy in oilfields.
