摘　　要：在分析草古 10 0区块水平井固井的工艺及难点的基础上 ,对机械式分级箍进行了改制 ,采用了双级注水泥工艺 ,在 9口水平井固井中的应用结果表明 ,该固井工艺满足了古潜山裂逢溶洞型特超稠油油藏开发的需求 。Based on analyzing the technology and difficulties in horizontal well cementing in Caogu 100 block, the mechanical stage collars are modified and two-stage cementing technique is used. The field application in nine wells show that this cementing technology satisfies the requirement of developing buried hill fracturing super-viscous reservoir. And obvious economical benefit is achieved.
