摘要: 为了提高绳索取心液动锤钻进技术在复杂地层的应用效果,提高无固相冲洗液维持孔壁稳定的能力,在PHP+GSP无固相冲洗液体系的基础上,添加了PVA1788冲洗液处理剂。按PHP、GSP、PVA1788比例为1∶5∶5混合,混合粉加量为1%~1.5%时,API滤失量为10~11 mL,漏斗粘度为18.4~21 s,塑性粘度为3.5~6 mPa·s,动切力为0.5~0.75 Pa。根据冲洗液试验及现场应用,该PVA1788无固相冲洗液体系具有粘度低、抑制防塌能力强、润滑性能好、使用维护方便等特点,大幅度提高了液动锤零配件的工作寿命,提高了钻机钻深能力,满足了复杂地层维护孔壁稳定、安全钻进的需要。本文对类似地层无固相冲洗液的推广应用具有参考价值。Abstract: In order to improve the performance of the wire-line coring hydro-hammer in complex formation and to improve the ability of solid-free drilling fluid to maintain the stability of hole walls, the PVA1788 flushing fluid treatment agent was added to tje PHP + GSP solid-free drilling fluid system. When the ratio of PHP, GSP and PVA1788 was 1∶5∶5 and the dosage of mixed powder was 1% to 1.5%, the solid-free drilling fluid performance was as below, APl water loss 10 to 11mL, funnel viscosity 18.4 to 21s, plastic viscosity 3.5 to 6mPa.s, yield stress 0.5 to 0.75Pa. Test and field application showed that the PVA1788 solid-free drilling fluid system had the characteristics of low viscosity, strong inhibition and anti-sloughing ability, good lubrication performance, and convenient operation and maintenance etc.; thus greatly improving the service life of hydro-hammer parts, increasing the drilling capability of drilling rig, and meeting the needs of maintaining stability of hole walls and safe drilling in complex formations. This paper has reference value for the popularization and application of the solid-free drilling fluid in similar formations.
