摘　　要：侧钻井技术是降低油田开发成本、挖掘老油田剩余油潜力、提高采收率、恢复长期关停的报废井、低效井等生产能力、提高油田经济效益的有利途径。一口井完井方式的合理与否,直接关系到今后的开发开采能否顺利进行。具体的完井方式必须与储层地质特性相适应。在大港油田实施的侧钻井中,储层普遍埋藏浅、压实程度低、胶结疏松、生产时容易出砂。把油藏是否出砂、井壁稳定与否、储层是否单一作为完井方式选择的主要依据。文章根据大港油田的具体情况,提出了确定完井方式的分析方法,并结合实际情况进行了现场的应用分析。In order to decrease the cost of development,excavate remaining oil potentiality of maturing oilfield,enhanced oil recovery,resume the production capacity of abandoned wells with long-term shutdown and inefficient wells and improve economic benefit and so on,side-track drilling technology is a advantage way.Extensional completion method must adapt to reservoir geologic characteristics.In side-track drilling of Dagang oilfield,drilled reservoirs were generally buried shallow,low compaction,and sanding easily while production.The main foundations to choose the completion method were whether the reservoir sanding,well bore stability,a single reservoir or not.According to the specific circumstances of Dagang Oilfield,the paper proposed out the analysis method to determine the completion method and carried out field application in term of the actual situation.
