滨海新区东营组地热热储回灌开采优化方案的研究

STUDY OF THE OPTIMAL EXPLOITATION AND REINJECTION IN BINHAI DONGYING GEOTHERMAL RESERVOIR

建立了天津滨海新区东营组热储层的物理和数学模型,分析了不同采灌模式对热储层压力场和温度场的变化特征和影响程度,提出了优化方案。结果表明:回灌能有效缓解热储层压力下降速率,延长热田寿命,并合理利用有限的热储资源。研究结果可为滨海新区地热资源的科学开发提供理论依据。

A physical and mathematical model of the Dongying geothermal reservoir in the Tianjin Binhai New District, China was set up to study the effects on pressure and temperature distribution of the porous geothermal reservoir under dif- ferent exploitation-reinjection patterns. The results indicate that reinjection is an effective way to slow down the pressure drop and prolong reservoir life, as well as to make an effective use of the geothermal resources. The result can provide theoretical basis for guiding the development of the geothermal resources in the Tianjin Binhai New District.
