复杂过渡带三维项目SPS文件数据的简化处理
|
摘要
SPS(Shell Processing Support Format)数据格式采用一种最简单的方式,提供了地震资料处理所需要的最基本的和完整的信息。对于复杂三维过渡带项目,由于数据内容复杂,更需要尽量保持SPS数据的这种简单化风格,主要表现在以下三个方面:一是由于炮点属性的不同(气枪炮、井炮或定位炮)不要人为编排带盘号和文件号;二是在SPS数据中不必标记坏道(指不正常道,而不是空道);三是在OBC排列移动时要注意简化处理。本文以BGP在海外完成的一个过渡带三维项目为例,对SPS数据进行了简化处理,效果明显。
SPS (Shell Processing Support Format) data format adopted a simplest way to provide the most fundamental and complete information the seismic data processing needed. For the 3D project in the complex transitional belt, the simplified style of SPS data shout be preserved as far as possible due to the complex data contents, mainly showing as follows: the first is that the manually numbering the number of tape and disk as well as file does not needed since the shot-point attribute is different (airgun, shot-in-well and positioning shot); the second is labeling dead trace (abnormal trace but not blank trace) does not needed in SPS data; the third is that it should pay attention to simplify processing when OBC spread moves. Taking a 3D project in transitional belt overseas finished by BGP as an example, the paper carried out simplified processing of SPS data, achieved good results.
