Y区块低伤害防漏失水泥浆体系研究

Research on Leakproof Cement Slurry System With Low Damage for Y Block

在钻井领域中经常遇到的井底复杂情况是井漏,井漏的发生随时可能诱发卡钻、井塌等井底事故的发生。针对Y区块所遇到的井漏情况进行了室内一系列防漏失水泥浆体系的研究,研究表明在低伤害防漏水常规密度的水泥浆体系中加入0.3%~0.4%的纤维,具有较好的堵漏效果,值得在Y区块后续钻进中进一步的推广与应用。

The circulation loss often happens in drilling field, which may cause some downhole accidents, such as drill pipe sticking, hole collapse and so on. Aiming at the circulation loss problem in Y block, leakproof cement slurry system was studied. The research shows that adding 0.3%-0.4% fiber into cement slurry system with conventional density and low damage can improve the sealing effect.
