能谱水流测井技术在西部油田的应用

摘要

针对油田在注水开发时,需要掌握水流具体流向哪个地层、流向每个小层的流量是多少以及中间是否发生水窜水漏等问题,采用能谱水流测井技术从最基本的注入剖面资料解释入手,运用西部油田的实例对能谱水流测井技术在识别水窜水漏位置、识别高渗条带、以及精细的定量解释上进行了研究.研究表明,能谱水流测井技术在动态监测水流方向、流速、流量上有着很高的精度,而且该方法对于油田以后的井组以及区域注采关系调整、最终提高采收率,均有着十分重要的意义.%In allusion to development of oilfield water injection,it is necessary to clarify some issues about the flow direction of the water flow;the flow rate to each layer,and whether there is any water leakage in the middle.Using the energy spectrum logging technology from the most basic injection profile data and the example of the western oil field to study the identification of the water and water leakage location,the identification of the high permeability band and the fine quantitative interpretation.The results show that,the energy spectrum logging technology has high accuracy in the direction,flow rate and flow rate of the dynamic monitoring of water flow,and it is very important to adjust the relationship between the well group and the regional injection and production relationship,and finally improve the oil recovery rate significance.
