大庆油田小井眼开窗侧钻水平井钻井技术

Horizontal well drilling technology by slim hole casing window sidetracking in Daqing Oilfield

针对大庆油田开发现状,开展小井眼侧钻水平井钻井技术的研究和应用,详细论述了小井眼开窗侧钻水平井钻井的工艺技术,使老井改造、加深、侧钻小井眼钻井技术及径向水平井等钻井完井配套技术得以快速发展,对大庆油田开发扶扬油层剩余油气、提高采收率和综合经济效益具有十分重要的意义。

Aimed at the exploitation actuality of Daqing Oilfield, this paper discusses the research and application of horizontal well drilling technology by slim hole casing window sidetracking. This will promote the development of the old well re-entry, sidetracking and radial horizontal technique etc. It is important in exploiting residual oil and gas in Fuyang layer reservoir and valuable for increasing recovery and integration economic benefit.
