本文简要叙述了具有润滑性能的乳化钻井液的使用和发展过程。国外用金刚石取心钻头和牙轮钻头进行试验研究的结果有力地说明,采用乳化钻井液会给防止钻杆振动、改善其受力,减少钻杆与套管磨损,增加钻头与涡轮钻具以及泥浆、水龙头易损件寿命,改善井身质量,提高钻井指标,减少事故,降低成本等方面带来综合性的好处。它是一项值得重视、很有发展前途的钻井技术措施。文章着重叙述了一些价廉而有效的润滑剂,如油脂厂的残渣СГ等的应用效果。
This article briefly describes the use and development of emulsified drilling fluids with lubricity. Abroad with diamond coring bit and roller cone drill test results strongly explained that the use of emulsion drilling fluid will give to prevent drill pipe vibration, to improve its force, to reduce the drill pipe and casing wear and tear, increase bit and turbine drill and Mud, faucet consumable life expectancy, improve well quality, improve drilling targets, reduce accidents, reduce costs and other aspects of the comprehensive benefits. It is a worthwhile and promising drilling technology measure. The article focuses on the description of some cheap and effective lubricant, such as grease plant residue СГ application effect.
