同位素示踪剂在双河油田区块调剖中的应用

Application of Isotopic Tracer in Profile - modification at Ⅳ4 Block of Shuanghe Oilfield

在双河油田Ⅳ4区块调剖中使用了同位素示踪剂。对示踪剂进行了筛选和用量设计.通过对示踪剂的检测和解释,得出高渗层的参数描述,并将渗透率、压力及剩余油饱和度等解释结果运用到调剖的数模调参及方案设计中,调剖后注入示踪剂对效果进行跟踪分析,该技术为调剖的实施提供了技术支撑,调剖后具有一定的增油降水效果。

Isotopic tracer was used in profile - modification at the Ⅳ 4 block in Shuanghe Oilfield. The screening and designing dosage of isotopic tracer were completed. The parameter of high - permeable layer was acquired by the inspection and explanation of tracer, the explanations for permeability, pressure and distribution of residual oil saturation were applied in the parameter- adjusting and project - designing of profile - modification, and the isotopic tracer was infused to track and analyze the effects after profile modification. The technique afforded support for the implementation of profile - modification. The oil - increasing and water - decreasing effects were showed after profile - modification.
