6 万道级采集技术在玛131 井区三维的集成创新

摘要/Abstract

摘要： 准噶尔盆地环玛湖地区油气资源丰富，勘探潜力巨大，但该区已有地震资料存在信噪比和分辨率低等问题，影响了优质储层预测、岩性圈闭落实和油气检测。针对该区地震资料存在的问题，依托玛131井区三维地震采集工程，开展了各种先进采集技术的集成应用研究。通过边试验边生产，解决了远距离数据通信、提高资料频宽、提高采集效率和实时质量控制等技术难题，最终实现了技术集成并在依托区和其他地区得到推广应用，资料品质明显改善。

Abstract: Areas around Mahu in the Junggar Basin contain abundant hydrocarbons, suggesting great potentials for exploration. However, low SNRs and resolutions of available seismic data for these areas negatively affect discovery of high-quality reservoirs, verification of lithologic traps and detection of hydrocarbons. In order to address these deficiencies, integration of various sophisticated acquisition techniques was considered for 3D seismic data acquisition in Well Ma-131 Block. By way of simultaneous tests and practical operations, the integration of techniques helped to address the technical problems in remote data transmission, widening of data frequencies, enhancement of data acquisition efficiency, real-time quality control and others. Eventually, the integration solution is successfully promoted and applied in Well Ma-131 Block and other areas, with quality of seismic data improved significantly.

Key words: 60000-channel acquisition, controllable seismic sources, real-time quality control, synchronous slip scanning, Junggar Basin, Well Ma-131 Block
