摘要
低压稠油油藏的开发。因钻井液技术不配套致使产层伤害。介绍了充气钻井液钻井技术的原理与组成及设计原则。充气钻井技术是将空气均匀地充入钻井基液中,形成气液混合流来降低环空液柱压力的一种低压钻井技术。经48口井现场应用表明,该项枝术能降低钻井液对油层的损害,提高油井产量,降低钻井成本,适于在低压低渗和易漏地层推广应用。
The technical mechanism and design principle of aerated drilling fluid are introduced. Application at 48 wells in Liaohe oil field indicate that aerated drilling fluid technique can reduce formation damage and increase well production, also the drilling cost can be decreased. Aerated drilling fluid technique is suitable for low pressure, low permeability and easily leaking reservoir.
