摘　　要：对于低渗油田，采用水力喷射定向钻孔技术可以松弛近井地层，清洗堵塞渗流通道。从而改变近井地带的应力分布和减小渗流阻力，提高低渗地层渗透率，克服钻井污染带的影响，是开发低渗透油藏和增产增注的有效方法。本文介绍了该技术在国内外的应用现状，并对2007年在长庆油田开展的5口试验井应用效果进行了初步分析，得到几点认识，并提出了该技术在长庆油田的应用前景，旨在为下步更好的开展该项工作提供借鉴。To the low permeability oil fields, using directional hydraulic jet drilling technology can loosen the forma- tion around wells, cleaning plug the flow channel, thus changing the stress distribution around wells and reduce the percolation resistance, inereased the permeability of strata. It is an effective way to develop low permeability reservoir and increase injection and production. Directional hydraulic jet drilling technology in the application status at home and abroad is introduced in this paper. Application to the five tested wells in 2007 in Changqing Oilfield is preliminarily analyzed. Some understanding is obtained. Prospects of application of the technology to Changqing Oilfield are put forward for retbrence to the next step work.
