摘　　要：针对新疆油田多种类型油气藏,在不同区块选用经过优化设计的复合射孔方案,对其生产效果与邻近采用常规射孔工艺的油气井进行了对比。结果表明,在中低渗油藏中的井中采用复合射孔工艺技术,增产增注效果显著,采液强度大幅度增高,有效提高了井筒与地层之间的渗流能力,使近井地带裂缝之间的沟通程度得到明显改善;但在物性较差和含油性差的油藏中,应用复合射孔技术,效果不明显。In view of veral types of oil and gas reservoirs in Xinjiang oilfield, the optimized composite perforation projects in different blocks are selected to make comparisons of the production effects with adjacent wells by conventional perforation technology. The results show that in medium-low permeability reservoir, adopting the composite perforation technology can get obvious responses in increasing production, increasing water injection and fluid producing intensity, and effectively improve the permeable ability between borehole and reservoir as well as the communication of near-wellbore fractures. However, in reservoirs with poor physical and oiliness properties, the effect could be unsatisfied by such a composite perforation technology.
