美国SWSI公司研发了一种新型地层图像系统OPTV。该系统应用光学成像原理在充满空气的井眼内获取高分辨率彩色地层图像,来展现极高分辨率的岩石结构和岩石节理裂隙,特别适合用来评价页岩气藏。OPTV可以用在3 813m长的标准多芯电缆装置上,通过牵引将OPTV送到水平井井底。应用该系统
US SWSI company developed a new type of formation image system OPTV. The system uses optical imaging principles to obtain high-resolution color formation images in an air-filled wellbore to present extremely high resolution rock structures and rock joint fractures that are particularly suitable for evaluating shale gas reservoirs. OPTV can be used on a standard 3,813-m long multi-core cable device that delivers OPTV to the horizontal well through traction. Apply this system
