在河南油田Ⅳ4层系整体调剖中应用了同位素示踪技术。通过对示踪剂产出曲线的解释,得出高渗层的各种参数,将解释结果应用到区块调剖的方案设计过程中,在调剖后又注入了示踪剂进行效果评价分析,表明渗流场发生了明显的变化。该技术的应用提高了调剖措施的有效性。
The isotope tracer technique was applied to the overall profile control of Ⅳ Ⅳ strata in Henan Oilfield. Through the interpretation of the tracer output curve, the parameters of the high permeability layer were obtained. The results were applied to the program design of the block profile control. After the profile control, tracer was injected to evaluate the effect , Indicating that the seepage field has undergone significant changes. The application of this technique improves the effectiveness of profile control measures.
