| 摘 要： | 天津滨海新区地热与石油资源同盆共存。为了更合理地开发油田地区地热资源,有效降低深部地热资源的开发风险,通过对油区深部东营组的地热资源热储、地温场、沉积相和流体化学等特征进行综合分析,总结了研究区东营组热储的富集规律。在此基础上利用数值模型计算了区内东营组地热资源100 a热流体开采资源量,并进行资源开采潜力评价。以开采潜力评价分区为基础,集成分析了地热资源有利勘探区应具的富油程度、规模大小、温度高低等要素的权重,对区内东营组地热资源有利勘探区进行分区。该研究对油区内深部地热资源的勘查及降低开发风险具有指导意义。

| Abstract: | The geothermal resources and petroleum coexist in Binhai New Area, Tianjin. In order to exploit and reduce the exploitation risk of the geothermal resources in oil field, the authors analyzed the thermal storage, geothermal field, sedimentary facies and fluid chemistry, and summaried the enrichment mechanism of thermal reservoir in Dongying Formation. The thermal fluid exploitation resources for 100 years were calculated by the numerical model, and the exploitation potential was evaluated. Then on the basis of the exploitation potential, the factor weight of oil-rich degree, size and temperature of geothermal resources in the favorable exploration areas was analyzed. The favorable exploration areas were partitioned. This research has important significance in the exploration of deep geothermal resources and the reduction of development risk in the oil area. |
