摘要
由于确定吸水剖面使用的同位素载体法在测井中存在问题,引进了示踪流量测井技术,对不同管柱注水井用示踪流量确定吸水剖面测井技术进行攻关,摸索出一套适合冀东油田不同管柱注水井"示踪流量确定吸水剖面"的测井方法。介绍了该技术的测试原理、测井工艺以及资料解释方法。针对冀东油田的实际情况,对示踪喷射器控制电路、喷嘴及仪器工作电压进行了改进,优选出示踪剂的类型和用量。分析了影响示踪流量计测量精度的因素,控制好示踪剂喷射速度、喷射时间、示踪喷射器喷嘴尺寸可以有效提高示踪流量计测井质量。进行了现场实验,通过与同位素载体法测井资料解释结果的对比,证明该方法适合在油田推广应用。
For existing problem of isotope carrier methods using for determination of injection profile at present, tracer flow survey technology is introduced, testing technology using tracer flow to determine injection profile for different casing injection well is tackled and a set of testing methods of using tracer flow to determine injection profile suitable for different casing injection well are fueled around. Testing principle of the technology, testing technology and data interpretation method are introduced. Against actual situation of Jidong Oilfield, tracer injector control circuit, nozzle and instrument work voltage are improved and type and dosage of tracer are selected preferentially. Factors of influencing testing precision of tracing flowmeter are analyzed, and controlling tracer ejected velocity, ejected time and size of tracer ejected nozzle may improve testing quality of tracing flowmeter. Field test proves that the methods above mentioned is suitable for development and application in oilfield, compared with testing data interpretation results of isotope carrier methods.
