摘要: 为了验证水力喷射侧钻径向微小水平井眼技术的可行性,在胜利油田进行了现场试验。测试研究了不同排量下的高压软管沿程压耗,并根据设计的多孔喷嘴,测试了该喷嘴的自进力。结果表明,高压软管内压耗较大,排量、前后向喷嘴流量比和井筒直径对喷嘴自进力影响较大,为施工时的水力参数设计及泵压预测提供了理论依据。在制定现场施工工艺的基础上,在胜利油田J17-1井进行了现场试验,在井深861.5和864.8 m处两个平面上共喷射钻出了4个孔眼,一个长度为20 m,其余3个为50 m,达到了预期目标。现场试验验证了连续油管水力喷射侧钻径向水平井系统的技术可行性,为老井改造和低渗油藏增产提供了一种新的技术途径。Abstract: A field test was carried out in a vertical Well J17-1 in Shengli Oilfield to validate the feasibility of hydra-jet sidetracking of micro-radial laterals,which could provide guidance for further research. The pressure loss in flexible hose was tested at different flow rates,and the ejecting force of self-propelled multi-port nozzle was tested. The results showed that the pressure loss in flexible hose was high,and the flow rate,ratio of the flow rate of the forward to that of backward port of the jet nozzle,and the wellbore diameter had significant effects on ejecting force,which provided guidance for hydraulic parameters design and pump pressure prediction during operation. Four laterals,one 20 m long and the other three 50 m long,were drilled in two different layers—861.5 m and 864.8 m based on well selection and the designed operation procedures,meeting the desired goals. The field test proved the reliability of the hydra-jet sidetracking of horizontal micro-radial hole,which provided a new way for stimulation of depleted oil wells and low-permeability reservoirs.
