可控震源驱动反拖曳问题的探讨

Exploration of vibroseis driven system anti-drag problem

石油地震勘探工区地形是影响可控震源施工进度及引发设备故障的重要因素之一。尤其是地表起伏大,沟壑较多的地表条件对可控震源驱动系统中泵和马达的工况及使用寿命有决定性影响。本文以EV-56高精度可控震源为例,详细分析了可控震源在施工中发生的反拖问题,并通过施工实例说明可控震源反拖造成的后果,最后提出了可行性建议及改进措施。

Topography is one of the important factors affecting vibroseis construction progress and equipment failure rate in petroleum seismic exploration area.Especially,the surface condition with large undulation and many furrows has a decisive influence on the working condition and service life of pump and motor in vibroseis driven system.In this paper,EV-56 high-precision vibroseis is taken as an example to analyze in detail the problem of anti-drag in the construction of vibroseis,and the consequences caused by anti-drag of vibroseis are illustrated through construction example.Finally,feasible suggestions and improvement measures are put forward.
