回灌技术在控制地下水位中的应用

回灌技术在石油开采以及控制地面沉降、防止引起防洪措施失效的应用实践表明,该技术经济效益好、施工简便,尤其对控制因地面沉降引起的防洪措施失效,有较好的效果。但目前在该技术的应用过程中缺乏设计依据,该文对回灌技术进行了分析、总结,给出了注水井群及抽水井群共同工作时的混合井群浸润线的求解方法,以及工程使用回灌技术求解抽水量和注水量、注水井深度确定方法和施工注意事项等,对工程实践具有一定的指导意义。

Application of Controlling Underwater Level

The application practice of the back-irrigation technology in the recover petroleum and the control of ground settlement causing losing efficacy of the flood control measures makes clearly that this technology has the good economical benefit and the easy construction,especially has better result for controlling the ground settlement causing losing efficacy of the flood control measures.But at present,there are the design data fallen short in the application of the technology.The article analyzes and sums up the back-irrigating technology,give the solving method of the infiltration line for the mixing well group of the filling-water well group and the pumping well group operated together,and the determining method to solve the pumping flow,filling flow and the filling well depth as well as the matters needing attention in the construction,which have some guidance significance for the engineering practice.
