摘要
海上水文环境的复杂性给开展浅层初至折射波法地震勘探带来一定困难 ,主要体现在潮汐、海流、涌浪等对观测系统产生较大影响 ,是海上工作的主要干扰因素。本文针对排列弯曲、炮点偏移距大小、炮点与检波器不在同一深度以及时距曲线偏移等问题进行了讨论 ,并提出了校正和解决的方法。
The surveying of refraction shooting on the shallow sea is affected by the complicated hydrologic condition, for example, tides, ocean currents, waves which is mainly the disturbance can be conduce a great affection to surveying system. In the paper, it is discussed to the winding of hydrophone array, the deviation and depth difference between focus and hydrophone array, and the deviation of time-distance curve, and presents a way to solve the problems.
