摘　　要：油气钻探中,钻遇地下水、地热等油气井伴生资源的情况十分普遍,油气勘探开发中因工程或油气开采枯竭等原因产生报废闲置井也是常见现象。对四川盆地东部历年所钻探的油气井进行统计和分析发现,现有报废闲置的油气井中,绝大部分井都曾钻遇地下水、地热(温泉)等可再生资源,具有较大的商业价值。而借助报废闲置井开发利用油气井伴生资源,不仅成本和风险低,而且可实现闲置资产的再次利用。为此,经过对市场、油气井伴生资源品质特征及油气井所处环境的研究,结合国内目前技术经济条件,探讨了川渝地区油气井伴生资源中地热、地下水的开发利用方向和技术途径。从国家能源供给和石油企业可持续发展的角度,提出了石油企业可利用现有技术、资源和人才优势,逐步向油气井伴生资源领域开拓延伸,进而实现油气井伴生资源开发利用的观点。It is usual occasions for oil and gas drilling to happen to meet many geothermal sources such as ground water, geothermal source, etc.; meanwhile the deserted or abandoned wells are commonly seen due to the depletion or some other reasons. Through statistical analysis on the drilled or explored wells during previous years, this paper found out that most of those wells would be proved with potentially great value in which ground water or geothermal sources (springs) could be reexplored. The revival of the abandoned wells could help oil companies lower down their investment and risk and also reuse the fixed asset again. Through studies on the quantities and market demand for those geothermal sources and assessments on the conditions and circumstances of the abandoned wells, this paper discussed upon the directions and technical ways to explore ground water and geothermal sources from those abandoned wells in Sichuan and Chongqing areas. In view of domestic energy supply and the sustained development strategy, this paper also put forward that oil companies should take full advantage of their present techniques, assets and human resources to extend their attention to the geothermal sources which would be potentially explored in many different ways.
