不压井作业用堵塞工具研制及应用

摘要

In order to meet the technical requirements of snubbing operation,slide block type tubing plug,tubing pressure operated bellmouth and retrievable packer tool were developed.This paper introduces the structure,working principle,technical parameters of these tools.It also introduces the construction steps of several kinds of snubbing operations.The technique was applied to 23 wells in 2011,which created the accumulated savings of RMB 3,553,700 and the production capacity of a single well was increased by 4 tons.%为了满足不压井作业的技术要求,研制了滑块式油管堵塞器、压通式喇叭口、投捞式堵塞器等工具.介绍了这些工具的结构、工作原理、技术参数.针对几种不压井作业,介绍了施工步骤.2011年共施工23口井,累计节约￥355.37万元,油井单井增油4t.
