摘要:
东濮凹陷西斜坡带新近系明化镇组砂岩热储地热井, 存在出砂严重和回灌困难的问题. 为了弄清东濮凹陷西斜坡带优质砂岩热储层地热地质特征, 综合考虑构造、储层和地温情况, 开展区域构造、地温场分布规律及热储精细解剖研究, 优化探井设计. 研究表明, 东濮凹陷西斜坡带新近系构造稳定, 馆陶组底板埋深2 000~2 200 m, 优质砂体发育在馆陶组下部1 800~2 200 m, 温度65℃以上, 热储物性较好, 具备地热资源开发潜力. 东濮凹陷西斜坡带长垣地区优化部署的馆陶组砂岩热储地热井试水结果与预测一致, 进一步证实了东濮凹陷西部斜坡带的地热勘探开发潜力.
Abstract:There are serious sand production and recharge difficulty in the sandstone reservoir geothermal wells of Neogene Minghuazhen Formation in the west slope belt of Dongpu Sag. To find out the geothermal geological characteristics of high-quality sandstone reservoir in the area, the paper studies the regional structure, distribution rule of geothermal field and detail of thermal reservoir, and optimizes the design of exploration wells combined with the structure, reservoir and geotemperature conditions. The results indicate that the Neogene structure in the west slope belt is stable with the floor depth of 2 000-2 200 m for Guantao Formation where the high-quality sandbodies are developed in its lower part (1 800-2 200 m) with the temperature above 65℃, showing good thermal storage property and development potential for geothermal resources. The hydraulic testing results of sandstone reservoir geothermal wells of Guantao Formation in Changyuan area are consistent with the prediction, which further confirms the geothermal exploration and development potential in the area.
