摘要
针对TKM工区初至认识困难,初至拾取工作量极大的难题,提出一种合理有效的,基于表层数据库的模型法静校正技术。该方法充分利用了工区内小折射,微测井布设密度足够且合理的条件,结合表层数据库及点、线、面一体化的表层交互分析解释方式,建立了全区合理的表层模型,计算生成最终静校正量。这项技术大幅度地提高了工作效率,且取得了满意的静校正效果。
In face to difficult problems that it is hard to recognize first breaks and the workload of picking up first breaks is extremely hard in TKM area,the paper presents a reasonable and effective model static correction technique based on surface database.Fully using of the condition that the distribution density of short refraction and Mini-logging data is enough and reasonable,combining with surface database,adopting the interactive analysis and interpretation methods of Spots and lines integration,the technique establishes a reasonable surface model in all area,and the final static corrections is finally calculated.This technique largely improves work efficiency and gets more satisfying model correction effect.
