测井法探测剩余油方法研究

摘要

This paper briefly introduces the detecting remaining oil saturation and the distribution method,compares their advantages and disadvantages and finally chooses the logging method to detect the residual oil.It is established based on the transient electromagnetic method in the three layer of columnar medium model,through the model of theoretical derivation and solution,calculated the formation of induction electromotive force.And through software simulation,it is intuitive description of the emission current;launch the number of turns of the coil,receiving distance on EMF effect.The method verifies the feasibility of detecting remaining oil.%本文简单介绍了探测剩余油饱和度和分布的方法,对比各自方法的优缺点,最终选择测井方法探测剩余油。从理论出发建立了基于瞬变电磁法的三层柱状介质模型,通过对模型理论的推导及求解,计算出了地层的感应电动势。并通过软件的仿真,直观地说明了发射电流、发射线圈匝数、收发距对感应电动势的影响,验证了此方法探测剩余油的可行性。
