摘要： 准噶尔盆地南缘油气资源丰富,圈闭众多,勘探程度低,难度大,是盆地最现实的油气勘探战略接替区。针对准噶尔盆地南缘的地质地貌特征,应以山地地震技术为主,查明地下构造型态。为此,要优化激发条件,应用已有的二维成果建立初始模型,建立适于复杂地下情况的观测系统;搞好山地近地表静校正,重视地震反射波成像的准确性;合理布置山地二维和三维地震,要打破不出油不上“三维”的陈旧观念。

Abstract: Southern margin of Junggar basin is characterized by abundant hydrocarbon resources and multiple traps,with low degree of prospecting and big difficulty for exploration. It is the most realistic strategic succession area for hydrocarbon prospecting in the basin. According to geologic and geomorphic features, to find out subsurface structural configuration should mainly depend on mountain seismic techniques. Hence, it is necessary to optimize induced polarization conditions, adopt available 2D result for developing initial model and observation system suitable to the complex subsurface situations; to carry out static correction near the mountain surface, pay attention to veracity in seismic reflection imaging; and to reasonably dispose mountain 2D and 3D seismic, an old idea of “cannot apply 3D unless yielding crude flow” must be cancelled.

Key words: Junggar basin, Tianshan Mountain, piedmont depression, oil and gas exploration, mountain seismic prospecting, seismic prospecting
