摘　　要：胶莱盆地是胜利油田的探区之一,而姜山洼陷又是胶莱坳陷中重点的烃源岩发育区。自从1979年就开始了地震勘探,由于山地地表地下双复杂的地质条件限制,所获得的地震资料品质一直较差,制约着地震勘探的进一步开展。2006年在该区开展了地震勘探攻关,应用了宽线地震采集技术,取得了良好的效果。本文就宽线技术的使用效果进行了对比分析,总结了宽线地震采集技术在该地区的应用前景。Jiaolai basin is one of the Shengli oil field prospecting areas. And more important hydrocarbon resource rocks had been accumulated in Jiangshan sag. Seismic exploration started in 1979 in the area. Because of the complexity of surface and geologic condition, acquired seismic data was always bad and now seismic prospecting continues hardly. In 2006 wide line seismic acquisition was applied for overcoming problems, and obtained well effects. The paper analyzes the results that different wide lines worked. And present the areas of uses for the wide line technique.
