反射地震勘探只能弄清地下构造的形态,构造中存在的流体是天然气,油还是水,应该有一个判别原则。但这种判别已经超过过去地震勘探的精度,不可能加以考虑。几年前,曾经介绍了由地震勘探结果绘制砂页岩比例图的方法,日本某海外石油开发企业曾为外国物探机构承担过试验工作,据说有能取得效果的适用场所,日本的技术工作者就较少关心用地震勘探直接找油气。
Reflective seismic exploration can only clarify the underground structure of the form, the structure of the existence of the fluid is natural gas, oil or water, there should be a principle of discrimination. However, this discrimination has surpassed the accuracy of seismic exploration in the past and can not be considered. A few years ago, the method of mapping sand shale from seismic exploration results was introduced. An overseas oil developer in Japan once undertook a test work for a foreign geophysical institute. It is said that there are suitable places for the effect to be achieved. Japanese technical workers Less concerned with seismic exploration directly to find oil and gas.
