在毛主席革命路线指引下,我国石油及天然气勘探事业迅速发展。地震勘探是找油找气的一个主要手段。地震资料搞得准,就可以为进行油气钻探提供可靠的依据,达到多快好省地扩大含油面积和增加石油储量的目的。五十年代,我国地震勘探使用的是苏式“51”型光点地震仪,只能搞出地下构造的大致轮廓;六十年代,发展到模拟磁带地震仪,地震勘探的精度有了一定的提高。但由于我国幅员辽阔,地层结构多样,这种地
Guided by Chairman Mao’s revolutionary line, the cause of oil and gas exploration in our country is rapidly developing. Seismic exploration is a major means of finding oil. With accurate seismic data, it can provide a reliable basis for oil and gas drilling and achieve the goal of expanding the oil area and increasing the oil reserves more quickly and economically. In the 1950s, the Soviet-style “51” light spot seismograph was used for seismic exploration in our country. Only the general outline of the underground structure can be worked out. In the 1960s, the accuracy of seismic exploration was improved to analogue tape seismometers improve. However, due to the vast territory of our country, stratigraphic structures are diverse and such places
