4) back off
解卡
1.
A totally new back off technology developed in field practice was introduced here.
介绍了一种在实践过程中摸索出来的全新的解卡技术,该技术通过先下入无接箍套管,边下套管边清洁环空,至套管鞋处,进行了长时间循环清砂,然后开泵下Φ244。
2.
The conglomerates had a compacting trend and formed a cylinder leading to freeze in the drilling tool when trying to back off by the drilling tool movement.
当试图通过活动解卡时,堆积物越挤越死,形成一个圆柱,卡死钻具。
5) unstuck
[英][,ʌn'stʌk] [美]['ʌn'stʌk]
解卡
1.
Tech of rush pipe for unstuck is using small diameter stem to low into tube and building a circulating channel for fluid in it to carry sand to surface by these channel and wash to manpower bottom (or ash surface) which provides a certain space for sand of outer of tube to sink.
冲管解卡工艺是将小直径的管柱下入到油管中,在油管中建立液流的循环通道,利用该通道把砂子带到地面,一直冲洗到人工井底(或灰面),给油管外的砂子下沉留有一定的口袋；若砂子不下沉,可以通过抽汲在沉砂上下建立压差,形成一定的压力激动,使砂子下沉,达到油管解卡的目的。
2.
127 mm tailed pipe perforated gun are used in two wells of Mo005-H10 and Mo017-H3 of Lei1 and Jialingjiang gas reservoir in Moxi natural gas field and unstuck accidents is happened after perforation.
由于射孔枪与套管间隙小,打捞工具选择困难,再加上水平井的特殊性,解卡工艺难度大,工程风险大。
6) forcible releasing

补充资料：解卡剂
分子式：
CAS号：
性质： 能降低钻具与地层面或井壁泥饼间的黏附力，降低阻系数，增加润滑性，抑制地层水化膨胀，以解除压差卡钻的处理剂。大多由清洁剂、皂类、渗透剂、润湿性调整剂及其他化学剂所组成。使用时，将解卡剂灌注到卡钻部位加以浸泡。
