摘要
多分支井是21世纪钻井领域的新兴技术,多分支井的技术难度很大,尤其是多分支井完井,完井成功与否直接关系到多分支井的应用效果。本文围绕多分支井完井过程中的关键技术和难点,简要介绍了多分支井的主要类型和适用储层条件,重点论述多分支井完井技术的发展现状和国内外先进的工艺和井下装备,指出优化空间构型、保证多分支井的连接性、隔离性、可进性是完井成功的关键。
In the 21st century,Multilateral well is a popular and challenging new technology in oil drilling industry.The new technology is so complicated,especially in well completion.The success of completion is directly related to the results of using multilateral wells.The paper discusses the development of multilateral well completion and advanced technology and completion methods.Some core technologies and difficulties are focused deeply,which points out optimizing configuration and confirming connectivity,isolation and accessibility are the keys of well completion.
