摘要

针对柴达木盆地复杂山地地震勘探多年攻关效果不佳问题,改变攻关思路,采用三维设计理念,利用宽线采集方法,通过灵活多样地选择施工机具、精细表层调查技术、高速层追踪岩性激发技术、因地制宜地选线选点技术、复杂区钻深井工艺技术、检波器埋置工艺接收技术、静校正技术等一系列实用物探新工艺、新技术、新方法,加强基础工作,严格野外施工,大大提高了单炮资料信噪比,改善了剖面品质,取得了良好的攻关效果。
Aiming at non-obvious results achieved by seismic survey in complex mountainous area in Qaidam Basin for many years, in complicate mountainous seismic survey of Qaidam Basin, it suggests changing seismic strategic ideas to adopt a series of practical geophysical new methods, new technology and new method, such as adopting 3D design concept, using the method of wide line acquiristion, selecting operation tool flexibly, fined surface survey technology, high-velocity layer tracing lithology shooting technology, the technology of selecting line and point suiting local conditions, deep hole drilling technology in complicated area, imbedding geophone receiving technology, static correcting technology, the fundamental work are strengthened, the field operation are strict to launch, the ratio of signal and noise of single shot are greatly improved, the qualities of profiles are improved, and saw the good strategic results.
