6) unstuck
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.

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。
