摘要
针对油田调剖设计中,与油藏水窜情况结合不足,部分参数仍依靠经验确定的问题,提出利用示踪剂测试技术指导调剖设计的思路。通过对目标井组注入示踪剂后检测示踪剂产出浓度,并利用半解析方法对检测结果进行解释,最终可得到注入水突进方向、速度,水窜通道体积、渗透率、孔喉半径等参数,从而明确井组水窜状况。结合上述信息,能够对调剖剂用量、强度、粒径等参数进行合理设计,消除经验设计中的不确定性。此次选择QHD32-6油田D02为目标井组,通过示踪剂结果指导了纳米微球调剖剂参数设计。调剖后,示踪剂解释得到的水窜严重突进单井的增油效果最为明显,证明了通过示踪剂结果指导调剖设计的合理性。
In profile control stimulation design, the water breakthrough information could not be considered well, parts of parameters would be still confirmed using experience. Aiming at this issue, a method that using tracer test technique to guide profile control design has been proposed. Inject tracers into target injectors, detect tracer concentration from producers, then analyze tracer results using interpretation software, several information could be obtained such as water breakthrough directions, velocities, volume/permeability/pore radius of water breakthrough channels. Use tracer interpretation results, consumption, strength and particle radius could be designed properly to abolish the previous uncertainty. In this paper, well D02 in oilfield QHD32-6 was targeted, the slug consumption of nanoparticles used for profile control was designed using tracer results. After profile control, oil was increasing obviously in the producers in which tracer result showed there was serious water flooding. It is concluded that designing profile control parameters using tracer technique is a good method in oilfield.
