Solving the static correction problems under complex near - surface conditions is a systematic engineering. first, careful field weathering investigation must be done, then we have to take full advantages of refraction first - break information and field weathering investigation information to compute field static correction and large residual static corrections with various refraction first - break statics methods, finally, reflection statics methods are used iteratively to solve the residual statics problems. to solve serious static correction problems in complex near - surface areas of western china, different refraction first - break statics methods are studied in this thesis. the main study contents are as follows : 1 ) the propagation features of refraction for horizontal layered and dip media are studied firstly, it lays a good theoretical foundation for later statics method studies
本文針對目前西部油氣勘探中迫切需要解決的復雜地表區靜校正技術難題，對初至折射波解決二維和三維長、短波長靜校正問題的正反演方法進行了深入的研究和探討，研究內容主要包括（ 1 ）水平層狀和傾斜界面折射波的傳播規律，為后續的折射靜校正方法研究奠定理論基礎； （ 2 ）二維復雜層狀介質地震折射波正演方法，該方法可適用於折射面起伏不大、低速層和折射層速度變化不大的情況。 -
