Energy Analysis of Geothermal Water In Medium and Low Permeability Reservoirs and The Design of Geothermal Water Replacing Surface Engineering Process Heat Suitable For Oilfields

With PetroChina promoting the integrated development of fossil energy and new energy, Daqing Oilfield has started the construction of a pilot demonstration area for clean energy substitution. Technicians analyzed the distribution characteristics of geothermal water in Songliao Basin, and screened out the reservoir areas with large-scale hot water resources and good thermal reservoir properties. According to the energy demands of the oilfield, we carried out the plan and design of geothermal water replacing surface engineering process heat suitable for the oil area. The plan and design covered the design of heat exchange process, the selection of ground engineering metering, treatment equipment, and the control measures for pollutants. The plan not only made full use of geothermal water energy in medium and low permeability reservoirs, but also considered relying on existing stations and abandoned well pad equipment to reduce the cost of test and engineering construction. We hope that the plan and design would provide guidance for accelerating the construction of new energy pilot demonstration projects and exploring the road for the green transformation of oil fields.
