介绍了钻井液用固相化学清洁剂ZSC - 2 0 1的室内合成及性能评价。结果表明 ,固相化学清洁剂ZSC -2 0 1具有较强的抑制性 ,可有效抑制粘土水化分散 ,保证钻井液清洁 ,在钻井液体系中与阴、阳离子型钻井液处理剂配伍性好 ,同时具有较好的抑制增效作用 ,在有效的加量内对钻井液滤失量和流变性等影响小 ,固相化学清洁剂ZSC - 2 0 1已在中原油田近 30口井中应用 ,具有良好的推广应用前景
The indoor synthesis and performance evaluation of drilling fluid solid phase chemical detergent ZSC - 2 0 1 are introduced. The results show that the solid chemical cleaning agent ZSC -2 0 1 has strong inhibition, which can effectively inhibit the hydration and dispersion of clay and ensure the drilling fluid is clean. In the drilling fluid system, the compatibility with the anionic and cationic drilling fluid treatment agents is good , While having a good inhibition of synergies within the effective dosage of fluid loss and rheological properties of drilling fluid less solid chemical cleaning agent ZSC - 2 0 1 Zhongyuan Oilfield has been applied in nearly 30 wells, Has a good prospect of promotion
