西安培训网摘要：A dual injection system for lectively injecting a treating fluid in a predetermined treating zone (16) of a well bore hole (10) adjacent a productive zone (14) with a marker fluid injected from the annulus (36) outside a coiled tubing string (34). The coiled tubing string (34) is inrted within the well bore hole (10) and a nsor (40) is provided on the coiled tubing string (34) with a lower end portion (42) extending below the nsor (40) for the discharge of the treating fluid from the lower end (44) of the extending end portion (42). The nsor (40) ns a detectable material, such as a radioactive material, in the marker fluid injected from the annulus (36) outside the coiled tubing string (34) and may be reciprocated within the well with the coiled tubing string (34) for determining the interface (46) between the marker fluid and the treating fluid so that the treating fluid does not enter the productive zone (18). In one embodiment (FIG.fez
4) the productive zone (14A) is located below the treating zone (16A) and the treating fluid contains the marker to provide the marker fluid.留学翻译
