摘要: 大地电磁场测量资料(CYT资料)多用于岩性探测。通过建立CYT资料与测井资料之间的转换关系,提出了利用CYT资料预测地层孔隙压力和地层破裂压力的新方法,有效地解决了预探井地层孔隙压力和地层破裂压力预测的难题。Abstract: The prediction of formation pore pressure and fracturing pressure is usually based on logging data and seismic data processing,however,little direct and reliable data is available for wildcat wells.This paper presents a new method by using of CYT data, which could be conveniently obtained through earth magnetic field measuring,to determine the lithology boundary and hydrocarbon reservoir depth.Its features and applications are introduced.
