近年来,自适应屏蔽暂堵钻井液技术在国内地区已经开始的应用,这种对钻井液进行防漏堵漏的技术以其优越的性能在石油天然气生产行业中弥补了常规堵漏技术适用范围较狭窄的缺陷。该技术可以对孔径分布范围较大的漏层形成快速有效的封堵,无须预知孔喉直径,适应性强。 In recent years, self-adaptive shielding temporary plugging drilling fluid technology in the domestic area has begun to apply this drilling fluid leakproof plugging technology with its superior performance in the oil and gas production industry to make up for the conventional plugging technology scope Narrow defects. The technology can form a fast and effective plugging of the drain layer with larger pore size distribution without the need to predict the pore throat diameter and has strong adaptability.
