COMMON TECHNICAL PROBLEMS OF GⅡ AIR GUN AND THEIR SOLUTIONS
-
摘要:
海洋地震勘探中使用的气枪主要有美国Bolt公司生产的BOLT枪、美国ION公司生产的S LEEVE枪、法国Sercel公司生产的G系列气枪3种.其中, Sercel公司生产的GⅡ型气枪与其他两种气枪相比具有结构简单、体积小、容积范围大、单枪威力能量强、同步性好、气枪后座力小等优点, 介绍了GⅡ枪在多道地震作业中出现的气枪点火、漏气、自激、注油等常见技术问题及其解决方法, 方便实用, 可大量节省对气枪的维修保养时间, 有效提高生产效率。
Abstract:The most popularly used air guns in marine seismic exploration include the BOLT gun produced by Bolt Company of the US, the SLEEVE gun produced by ION Company of the US and the G series of air gun produced by Sercel Company of France. Compared with the other two kinds of air guns, the GⅡ air gun produced by Sercel Company has the advantages of simple structure, small size, large volume range, strong single gun power, good synchronization and small air gun recoil force. This paper introduces some common technical problems, such as the air gun ignition, air leakage, self-excitation and oil injection in multi-channel seismic operation, and their possible solutions, which are convenient, practical, economic and time saving for maintenance.
