砂岩热储完井工艺对采灌能力的对比研究OA

The production-injection capacity of geothermal wells determines the overall efficiency and sustainable development of sandstone thermal reservoirs.At present,geothermal wells mainly adopt traditional screen pipe well completion methods,which generally face the problem of difficult reinjection.Taking the Guantao Formation sandstone thermal reservoir in Hekou District,Dongying as an example,a comparative analysis and study were conducted on the adaptability,produced water quality,and production-injection capacity of two well completion techniques:screen pipe completion and perforated completion.The results show that the production-injection capacity and produced water quality of geothermal wells with perforated completion are superior to those with screen pipe completion.
