Exploitation and Utilization Technology of Geothermal Resource in Oil Field

Abstract

There are plenty of geothermal resources in oil & gas sedimentary basin. Under the conditions of short supply of energy and rapid development of new energy, the geothermal resource in oil & gas field causes more and more attentions. Based on the analysis of the geothermal resource in oil & gas field, the possible mode of coproduction geothermal from oil & gas field was discussed. Considering the existing low- and medium- temperature cogeneration technology, the feasibility of using the low- and medium- temperature geothermal resource in oil & gas field to produce power was analyzed. With the characteristics of geopressured geothermal resource, the potential of using geopressured geothermal water flooding in heavy oil reservoir to improve oil recovery was also investigated. From these studies, it is concluded that sustainable development of oil & gas field and efficient utilization of new energy can be realized through the win-win cooperation between oil & gas production and geothermal exploitation based on the existing infrastructure, technology, and experience and reservoir information in the oil field.
