摘要针对目前钻并液常规润滑剂极压膜强度低、抗湿性能差、润滑持效性差等问题,首先将植物油和含硫、磷、钼等活性元素的有机钼化合物反应,合成出有机钼减摩剂,然后将其与10"白油进行复配,制备出了极压润滑剂JM-1。性能评价结果表明,JM-1加量为1.5%时,极压润滑系数降低率大于65%,有较高的极压膜强度,润滑持效性好,抗温达150℃,无毒,无污染,荧光级别较低,与钻井液体系配伍性良好,不引起钻井液发泡。该润滑剂在大斜度定向并腰1-1HF井和北港1并进行了现场应用。在腰1-1HF并使用了该润滑剂后,水平段提升摩阻降低50%,全井起下钻、下套管顺利。北港1 并后期划眼复杂期间使用该润滑剂,钻并液的润滑性能得到了明显改善,并眼培塌现象也得到了有效将制。

Abstract Common drilling fluid lubricants have problems such as low film strengths at extreme pressure, poor stability at elevated temperatures, and short lubricity persistence in extreme conditions. An extreme pressure lubricant, JM-1, has been developed by mixing an organic molybdenumfriction reducer and the 1o white oil. The organic molybdenum fiction reducer was made by reacting vegetable oils with organicmolybdenum containing sulfur, phosphorus and molybdenum. The percent reduction in friction at extreme eoeoaseeeneer%e%es lubricity remains stable at 15o °C. JM-1 is non-toxic, pollution-free, and has low fluorescence Drilling fluids treated with JM-1 do not foam. JM-1 has been tried in the highly deviated directional well Yao1-1HF, in which the friction in the horizontal section was reduced by 50%, and tripping and casing running were conducted smoothly, and well Beigang1, in which reaming was done much easier afte using JM-1 treated drilling fluid.

0引言
近年来,随着定向钻井技术的推广应用,特别是大斜度、大位移定向井和水平井的逐渐增多,钻并摩阻问题尤为突出,对钻井液润滑剂性能提出了更高的要求[1-2]
目前,常用的润滑剂在现场实际应用中存在极压膜强度低、润滑持效性差、荧光级别高、抗温性能差等问题3-4),难以满足定向井高侧压力条件下的要求,尤其是大斜度、大位移定向井和水平井的需求。因此,如何解决在极高的压力条件下,保持高效的润滑性能是至关重要的。
