多道自然电场法在石油勘探中的应用
|
摘要
在陕北油田的勘探阶段,采用多道自然电场法勘探,即数字化多点同步采集,单点记录一个时间序列的拟地震采集技术,合适地消除非油气电场异常的处理技术以及综合解释技术,经实践检验,是一种切合实际并有效的方法。与以往模拟仪器采集、单点记录1～3个电位值的方法技术比较,抗干扰能力、精度和可靠性都得到了很大提高,为寻找有利的油气勘探靶区奠定了基础。
At the exploration stage of Shanbei oil-field,adopting multichannel spontaneous electric field method to explore,namely digitized multipoint synchronous collection,which is the analogy seismic collecting technology of a single-shot recording a time sequence,the processing technology and the comprehensive interpretation technology of removing non-oil/gas's abnormality of electric field,through the inspection of practice,is a kind of practical and effectively method.In comparison with the technology of anciently analogy instrument collecting,single-shot recording 1-3 current potentials,the ability of noise immunity,accuracy degree and credibility all got to raise very greatly.It will lay a good foundation for searching beneficial oil/gas survey area.
