摘要
1991年,在江苏J油田开展综合电法试验,旨在探索电法新技术在寻找含油气构造中的应用效果和前景,确定J油田主要油气藏类型的综合地电模型及其在地面电法勘探中的异常效应。本次试验,用大地电磁法(MT)、声频大地电磁法(AMT)和可控声频大地电磁法(CSAMT)研究地层和构造.用激发极化法(IP)和频谱激电法(SIP)直接寻找油气藏:试验资料与三维地震、钻井、测井结果对比表明.综合电法试验反映的地质构造、油气储集层与实际情况吻合。本文简要介绍CSAMT、IP、SIP三种电法技术的方法原理、关键技术以及试验效果。
In J oil field.Jiangsu. 1991.a comprehensive experiment of electric survey methods was made to ascertain feasibility of new electric survey technique in hydrocarbon bearing structure exploration, and to determine both geological electric models of major hydrocarbon accumulations in J oil field and their abnormal effects in surface electric survey. Magnetotelluric (MT ), Audiomagnetotelluric (AMT ) and controlled source audiomagnetotelluric (CSAMT) methods were tested to research into formation and structure. Induced polarization (IP)and spectral induced polarization (SIP) were adopted to discover hydrocarbon accumulations directly. The comparison shows that the geologic structure and hydrocarbon accumulation which have been with those discovered by 3D seismic.drilling and logging data. The paper briefly describes the basic principles.key skills and trial effects of CSAMT.IP and SIP.
