双相介质动态形变会引起 3种不同的震电效应 ,给地震波场施加外部电场 ,通过震电效应可以改善地震波传播环境 ,提高地震资料的信噪比。在芳深 90 1井进行了以了解该井处的地震波场和电磁场相互作用为目的的VSP观测 ,并综合运用震电效应对该井进行了建场VSP的处理解释 ,所取得的结果表明建场VSP的应用效果明显地优于常规VSP。
Dynamic deformation of two-phase medium can cause three different kinds of electroelastic effects, which can exert an external electric field on the seismic wave field. The seismic wave propagation environment can be improved by the electro-seismic effect, and the signal-to-noise ratio of the seismic data can be improved. The VSP observation for the purpose of understanding the interaction between the seismic wave field and the electromagnetic field at Fang Wei 90 1 well was carried out and the VSP treatment of the well was carried out synthetically by using the electronegative effect. The results obtained show that The effect of field VSP is obviously better than that of conventional VSP.
