But it has more complicated velocities in the working area, and it locally develops high-speed boulder bed in neocene Xiyu Formation with a velocity 3700—4050m/s, its adjacent formation velocity: 2800—2900m/s; while it also develops low velocity gyprock that has a great variation in thickness (with an increasing thickness from south to north) with a velocity about 4000 m/s, its adjacent formation velocity: about 5000 m/s. And all this is the cause of the complexity of the velocity in this working area; thus to make the No.1 structure in northern YK reliable, in velocity modeling it has much research work to do, and it is also the topic of this graduation thesis.
但在工区内速度较为复杂,工区内局部发育上第三系西域组高速砾岩层,速度约在3700—4050m/s ,围岩速度约在2800—2900m/s,同时全区还发育有厚度变化较大的低速膏岩层,膏盐层的速度大约在4000 m/s,围岩的速度大约在5000 m/s,由此造成了本工区速度的复杂性,因此要准确落实亚肯北1号构造,还要在速度建模等方面做许多的研究工作,这也是本次毕业论文所要研究的课题。
