钻井液与完井液

中国陆上石油工业钻井液与完井液技术新进展

The new development of drilling and completion fluids technology , China onshore oil industry

该体系在该区3口井中应用，表现出极强的抑制效果，密度低、钻速快，有效地防止了井塌，保护了气层，实现了钻井液与完井液的统一。

The application of this system in 3 wells shows its good inhibiting effect , low density and high drilling rate . And this is helpful for the unity of well completion fluid with drilling fluid to prevent well slough and protect gas zone .

结合岩心流动实验仪或者岩心多段渗透率梯度仪就可以评价出岩心各段受入井流体损害的深度和程度，从而优选出满足保护油气层需要的钻井液与完井液体系。

Coupled with the core flow testing apparatus and the core multipoint permeability gradient meter , the damage depth and level of the core caused by the fluid can be determined , thereby the optimized drilling and completion fluids that meet the requirements of reservoir protection can be selected .

钻井液动滤失模拟系统用于在实验室的环境下，模拟实验钻井液与完井液对油气层的综合损害过程，以达到评选优质钻井液和完井液的目的。

Aim to select excellent drilling fluid and completion fluid , the multiple damage process of the fluids to reservoir were simulated in laboratory by dynamic water loss simulation system .
