摘要

提出适合低渗透油田完井使用的油层保护完井管柱。介绍了研制的油层保护完井控制管柱、井下防喷管柱及组成管柱的主要工具。这项技术有效地解决了清蜡、洗井等入井液及压井液对油层的伤害问题,对低渗透油田开采过程中的油层保护具有重要的意义。

Abstract

The well completion pipe-string for formation damage preventing in lowpermeability pools was introduced including well-completion controlling pipe-string, blowout prevention pipe-string and main tools. The formation damage in wax removal, well-flushing and well-killing job were solved by the technique. It has a important role for formation protection in development of low-permeability oilfield.
