| Abstract |
Petroliferous sedimentary basins usually have good geothermal resource potential, as well as rich geological data and oil wells. By utilizing mature and abandoned oil wells to strengthen the development of geothermal resources in oil fields, it can significantly reduce the impact and promote the coordinated development of Petroleum and geothermal resources, and promote the adjustment of the energy structure of oil production. This study systematically analyzed the geothermal geology, distribution of thermal reservoirs, and geothermal field in the Gudong area of Shengli oilfield, SINOPEC. Based on the distribution of mature and abandoned oil wells and energy demand, two mature oil wells were selected for renovation and testing. The results show that the thermal reservoir layer is carbonate rock of the Lower Paleozoic Ordovician, and a temperature of 136.8 ℃ was obtained at a depth of 3110 meters. The expected annual water production is 840960m3, and the annual recoverable heat is 4.28 * 1014J, equivalent to 14627t of standard coal. |
