摘　　要：针对提高储层打开程度、改善近井地带渗透率而开发的水力割缝技术 ,利用高压含砂水流对井壁及地层切割 ,产生宽 2 0mm、深 1 0 0 0mm的缝洞 ,从而通过改变近井地带的渗流条件、应力及渗流分布 ,降低油流阻力 ,实现增产增注。经现场实施证实 ,该技术是油田低渗层。A hydraulic slotted liner technique is developed in order to enlarge perforation interval of formations and to improve permeability round a well. A fracture with 20mm width and 1000mm depth may be formed by the technique. Around the well, it is the fracture that may reform permeability conditions and change the stress distribution so that the flow resistance will be reduced, and either production or injection will be enhanced. It is expressed by field applications that the technique is efficient to increase production in low permeability reservoir or in heavy oil layers.
