The Seismic Acquisition Technology for Double Complex Areas in the Southern Margin of the Junggar Basin

doi:10.12388/j.issn.1673-2677.2025.04.001

Abstract

Abstract:

Due to the complex surface seismic geological conditions and complex deep seismic wave field and structural characteristics，the overall seismic data signal-to-noise ratio in the southern margin of the Junggar Basin is low，making it difficult to accurately analyze the structure，which has seriously affected the oil and gas exploration process. With the significant breakthrough of the GT1 well in the lower combination，the overall deployment of the area has implemented wide azimuth，wide bandwidth and high density seismic exploration project covering more than 3 800 km² in steps over the past five years. In the seismic data acquisition phase of these exploration projects，a series of targeted technologies have been applied，including surface conglomerate survey techniques，laser radar aerial information—assisted shot points pre-design，and well-seismic mixed source efficient acquisition techniques. These technologies have enabled the annual increase in shot density within the affordable cost range. After several years of integrated technical breakthroughs，the imaging effect of seismic data in this area has been greatly improved，and the well-seismic error has been significantly reduced. The seismic acquisition technology in the dual complex area on the southern margin of the Junggar Basin is of great reference significance for similar seismic acquisition projects in exploration areas.

Key words:

the southern margin of the Junggar Basin；double complex；wide azimuth, wide bandwidth and high density；conglomerate surveys；efficient acquisition supporting technology

摘要：

复杂的表层地震地质条件和复杂的深层地震波场及构造特征，致使准噶尔盆地南缘整体地震资料信噪比低，构造精细解析困难，严重影响了油气勘探进程。随着高探1井在下组合获重大突破，近5年来该区整体部署、分步实施了超过3 800 km²的“两宽一高”（宽方位、宽频、高密度）地震勘探项目。在这些勘探项目的地震资料采集环节中，表层巨厚砾岩调查、基于高清地理信息激发点预设计、井震混源高效激发采集等一系列针对性技术的应用，实现了在成本可承受范围内，炮道密度逐年提高。经几年的一体化技术攻关，该区地震资料成像效果得到了大幅提升，井震误差明显降低。准噶尔盆地南缘双复杂区地震采集技术对类似探区地震采集项目极具参考意义。
