摘要
可控震源极性直接关系到采集资料的极性,因此可控震源极性测试是震源项目开工必测项目。节点仪器应用越来越广泛,节点仪器施工中,可控震源极性测试方法、测试设备都和过去传统的有线仪器中测试方法不同,变的更加复杂,新的测试方式和方法带来新的挑战,本文结合生产实例从SEG震源极性测试要、测试目的等方面进行阐述,完整的梳理了,震源极性测试中的方法和测试步骤,并且对比了节点仪器和有线仪器在反SEG极性要求下的差别以及原因。
Vibroseis polarity is directly related to the polarity of the acquisition data,so the vibroseis polarity test is a must for the start of the vibroseis project.The node instrumentation is becoming more and more widely used,and the test methods and test equipment for vibroseis polarity testing in the construction of node instrumentation are different from those in the traditional wired instrumentation in the past,and become more complex,and the new test methods and methods bring new challenges.The paper also compares the differences between nodal and wired instruments in terms of anti-SEG polarity requirements and the reasons for them.In the construction of node instruments,the vibroseis e polarity test method is different from the past and brings new challenges.This paper combines production examples to elaborate from the principle,test purpose and requirements,which is of guidance for field production.
