最近加拿大Quest取芯公司采用快速岩心电缆可回收取芯系统,在美国科罗拉多州Niobrara页岩中创下了单次作业获取120英尺31/2英寸的岩心记录。一月,Quest与Reservoir集团合作推广该项大孔径取芯技术。新近展包括超声电缆成像仪、电磁卡点指示器、有线和光纤挠性管系统以及超高温LWD仪器。由于水平井钻井急剧增加,非常规储层又是发 Recently, Canada’s Quest coring used a rapid core cable recyclable coring system to create a single-shot 120-foot 31/2 inch core record in a Niobrara shale, Colorado, USA. In January, Quest partnered with Reservoir Group to promote the macropore coring technology. Recent exhibitions include ultrasonic cable imagers, electromagnetic card point indicators, wired and fiber optic flexible pipe systems, and ultra-high temperature LWD instruments. Due to the drastic increase of horizontal well drilling, unconventional reservoirs are again sent
