摘　　要：经过近几年普通射孔在现场中的应用分析 ,发现其存在着无法解除地层污染、射孔形成的渗流面积小 ,同时易造成二次污染等问题。为了解决这一问题 ,将普通射孔与高能气体压裂分开进行的方式改为一次进行的方式 ,即复合射孔技术 ,在王家岗油田王 5 4 1沙三中油藏开发实践中应用 ,事实证明 ,复合射孔技术比普通射孔技术产能增加近 3.5倍 。By analyzing of the field application of normal perforate technique,it was found that there exist many problems, for example, it can't relieve the formation pollution,the seepage area produced by perforating is small, and it is prone to cause formation contamination for the second time. It has solved the problem more perfectly through the application of compound perforation technique in the Es3 reservoir of Wang542 fault block in Wangjiagang Oil Field, and notable effect of oil increment has been obtained.
