中文摘要:维持钻孔孔壁的稳定性是复杂地层钻进中的关键问题之一。对以沥青为主的ABD-1复合堵漏钻井液体系进行性能分析表明,塑性沥青在05~16 cm宽的裂隙内能扩展5~7 m,而在小裂隙中扩展量在1 m以内;同时辅以表面活性剂OP-10和膨润土等材料进行现场应用,效果明显。在泥砂地层顺利完成了裸孔430余米的钻进工作。该材料来源广,具有很强的适用性。 |

Abstract:Borehole stability is a key problem in complex formation drilling. According to the analysis on ABD-1 compound drilling fluid that bases mainly on asphalt, plastic asphalt can expand 5~7m in the fissure of 0.5~16cm, but only 1m in the smaller cranny. Field application was made on ABD-1 compound drilling fluid assisted by surfactant and bentonite, more than 430m drilling in sand and mud layer was completed. |
