采用小井眼技术进行开采，主要是为解决外围低产油田开发投资大、经济效益差的问题。大庆油田从１９９６年开始陆续投产了几批小井眼井，取得了一定的经验和认识。介绍了大庆外围小井眼的采油生产和工艺配套情况，从注水、机械采油、压裂、大修等方面分析了不同管柱在不同情况下的受力情况，从安全角度界定了小井眼不同管柱的下入深度，从经济角度优选了各种管柱，并对不同工艺的适应性进行了分析，探索了小井眼开采在外围油田开发钻采技术和经济上的可行性。
The use of slim hole technology for mining, mainly to solve the low-yield peripheral oil field development of large investment, poor economic efficiency issues. Since 1996, Daqing Oilfield has put into operation several batches of slim wells and achieved some experience and understanding. The paper introduces the oil production and process matching of the peripheral slim hole in Daqing, analyzes the stress of different pipe strings under different conditions from the aspects of water injection, mechanical oil production, fracturing and overhauling, and defines the different strings Depth analysis of pipelines from different perspectives, and analyzed the suitability of different technologies and explored the feasibility of economically exploiting drilling technology in peripheral oilfields.
