细分注水液力投捞技术的研究与应用

细分注水液力投捞技术是采用井口注水源为动力进行液力投捞，可一次投捞两级配水器芯子和5支井下电子流量计，并同时测试5层水量、调配5层水咀，测试调配效率高；通过管柱机械定位使封隔器在最小坐封段仅O．89m的距离上准确卡封，最小卡封距达1．8m，可实现连续的薄夹层和薄注入层的细分注水；管柱类型为井口悬挂式，不仅适合浅井细分注水，同样适合于深井、斜井细分注水。该技术己在现场试验应用15井次，工艺成功率和有效率达100%，达到了细分注水、测试的目的。

Study and application of subdivided layers water injection technology by hydraulic running and pulling

By hydraulic means, this technology can run and pull. At one time, it can test simultaneously flow rate and regulate water nozzles in five injecting zones with higher efficiency. A packer can be set and sealed accurately in the minimum setting interval of 0.89m with mininum sticking and sealing distance of 1.8m by mechanical tubing string locator, allowing for successive thin interbred and injection layers to be water injected sub dividedly. The type of injecting string is hanging one at wellhead, suitable for both shallow wells and deep and deviated wells. The technology has been tested in 14 wells with both of success rate and effective rate of 100%.
