高精度磁测直接找油方法技术

THE TECHNIQUE OF DIRECT SEARCH FOR OIL BY THE HIGH-PRECISION MAGNETIC MEASUREMENT

本文从成岩磁铁矿理论出发,讨论了油气藏上方的磁异常形态,阐述了利用高精度磁测直接寻找油气田的可能性及其方法技术。文章指出,用磁测直接找油,不仅要提高磁测精度,而且关键在于要能找到并能成功提取与油气藏有关的磁异常信息的方法。文中还列举了引用本文所述方法预测油气田的效果。

In this paper the writers discussed the distribution of magnetic anomaly above some oil and gas deposits by using the theory on forming magnetic pyrite and expounded the possibility and the technique of direct search for oil by the high-preci sioa magnetic measument. They concluded that by using magnetic measurement to searck for oil, its precision can be raised and a new method to seperate the anomaly from the total anomaly can be developed to succeed in acquiring the information about the magnetic signature concerning oil and gas accumulation. Finally, they enumarated several examples to show the effects for predicting oil and gas by using the technique discribed ia this paper.
