大王庄油田地热资源可持续利用研究

Research on Sustainable Utilization of Geothermal Resources in Dawangzhuang Oilfield

华北油田按照“清洁替代、战略接替、绿色转型”三步走总体部署,建设化石能源与清洁能源全面融合发展的“低碳能源生态圈”。以第三采油厂大王庄油田为例,大王庄油田采出液温度较高,可通过调整开发方式,变传统油-气开发为油-气-热协同开发,实现对油气矿权范围内与油气伴生共存的地下地热资源开发利用。在开发过程中,采用“全密闭、全回灌、取热不取水”等保护性开发技术,能够保证油田地热资源的可持续利用。油田地热资源是一种可再生能源,油田站场积极利用地热资源,打造无烟站场,能够加快中国石油实现低碳发展的步伐,符合科学发展观、循环经济和可持续发展的要求,切合国家的“碳中和”战略,对华北油田改变能源结构,发展循环经济,建设资源节约型、环境友好型企业将起到促进的作用。

Huabei Oilfield follows the three-step overall deployment of"clean substitution,strategic succession,and green transformation"to build a"low-carbon energy ecosystem"that integrates fossil energy and clean energy.Taking the Dawangzhuang Oilfield of the No.3 Oil Production Plant as an ex-ample,the produced fluid temperature of the Dawangzhuang Oilfield is relatively high.Traditional oil gas development can be transformed into oil-gas-thermal collaborative development by adjusting the development method,achieving the development and utilization of underground geothermal resources coexisting with oil and gas within the scope of oil and gas mining rights.In the development process,the use of protective development technologies such as"full airtightness,full recharge,and heat extrac-tion without water extraction"can ensure the sustainable utilization of oilfield geothermal resources.Oil-field geothermal resource is a kind of renewable energy.Active use of geothermal resources in oilfield stations to build smoke-free stations can speed up the pace of PetroChina's low-carbon development,meet the requirements of the scientific concept of development,circular economy,and sustainable de-velopment,and correspond with the country's"carbon neutrality"strategy.At the same time,it will play a catalytic role in changing the energy structure of Huabei Oilfield,developing a circular econo-my,and building a resource-saving and environment-friendly enterprise.
