针对棋北三井油层与高压盐水层间高压差可能引发的压差卡钻问题,采用固体润滑塑料小球,用以改变钻具与泥饼的接触状态,降低钻具与泥饼摩阻系数,从而改善钻井液的润滑性能、提高防卡能力。经室内试验及现场应用证明,该润滑剂具有独特而优异的防卡能力,还具有化学惰性,无荧光、对钻井液性能无不良影响等特点,较好地解决了棋北三井高密度、高压差条件下钻井液的防粘卡问题。
Aiming at the problem of differential pressure sticking, which may be caused by the high pressure difference between the Bei Mitsui reservoir and the high pressure brine, a solid lubricating plastic ball is used to change the contact state between the drilling tool and the mud cake and reduce the friction coefficient between the drilling tool and the mud cake, So as to improve the lubrication performance of drilling fluid and improve anti-jamming ability. The indoor test and field application proved that the lubricant has a unique and excellent anti-card ability, but also has chemical inertness, no fluorescence, no adverse effect on drilling fluid properties and other characteristics of a good solution to the chess Kita Mitsui high density, high pressure Poor conditions of drilling fluid anti-stick problem.
