摘要
钻井液用固相化学清洁剂ZSC-201已应用于中原油田不同区块的10多口油井。应用结果表明,ZSC-201能有效抑制泥页岩的水化膨胀分散,清除钻井液中的有害固相,减少钻井液中亚微粒子含量,保证钻井液清洁。所应用井段膨润土含量上升缓慢,钻井液塑性粘度和动切力容易控制,维护简单,大大减少了处理剂的种类和用量,避免替换泥浆,从而节约了泥浆成本;有效控制了固相含量,有利于提高机械钻速。
The application results in ten wells of Zhongyuan Oil Field showed that ZSC - 201 had very good capacities of inhibiting shale hydration, cleaning out nocuous solid, and reducing sub - corpuscule in drilling fluid, and good heat resistance and salt tolerance. The application of ZSC - 201 could reduce the cost of drilling fluid and is advantageous to improving the rate of mechanical drilling well. It showed good economic and social benefits that ZSC - 201 was applied in Zhongyuan Oil Field.
