摘要
在分析地质概况、储层损害因素及各种欠平衡钻井液体系性能评价的基础上,SN98井三开负压井段优选了乳化柴油钻井液(密度稳定在0.84～0.86kg/L),并给出了其配方及性能指标。现场应用证明,该钻井液体系能满足欠平衡钻井的要求,具有较好的稳定井壁能力,机械钻速提高2～4倍,值得推广应用。
Field applications show that this drilling fluid system can meet the demand for UBD and has better capability of stabilizing well bores. The penetration rate can be improved by two to four times. This drilling fluid system is deserved to be widely used.
