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。
The southern margin of the Junggar Basin is rich in oil and gas resources, has many traps, has a low degree of exploration and is very difficult. It is the most realistic oil and gas exploration succession zone in the basin. According to the geomorphic features of the southern margin of Junggar Basin, the earthquakes should be based on the mountainous earthquakes, and the underground tectonics should be identified. To this end, to optimize the excitation conditions, the application of the existing two-dimensional results to establish the initial model, the establishment of an observation system suitable for complex underground conditions; improve the near surface static correction, emphasis on seismic reflection imaging accuracy; Dimensional and three-dimensional earthquakes, it is necessary to break the old notion that “there is no oil in three dimensions”.
