未来的油气勘探是希望和困难并存,一方面勘探形势与技术进步给勘探带来了很多机遇;另一方面随着勘探程度的加深与提高,油田地质日趋复杂,勘探难度将越来越大。也就是说,全球油气经过一百余年的勘探,目前均进入复杂油气勘探阶段。今后新发现的油气田规模将减小,探井的风险性将变大,沉积物的特征将更复杂,勘探目的层的深度将会更大。据第十五届世界石油大会报道,本世纪末石油勘探的基本趋势是:①在长期勘探的盆地,特别是长期勘探的远景区中,新发现(指新发现油气田和油气聚
In the future, oil and gas exploration is hope and difficulty coexist. On the one hand, the exploration situation and technological progress have brought many opportunities for exploration. On the other hand, as the degree of exploration deepens and improves, the geology of oilfields will become increasingly complicated and exploration will become more and more difficult. In other words, after more than one hundred years of exploration, the global oil and gas fields have now entered the stage of complex oil and gas exploration. In the future, the newly discovered oil and gas fields will be reduced in size, the risk of exploratory wells will be greater, the characteristics of sediments will be more complex, and the depth of the exploration target layer will be greater. According to the 15th World Petroleum Congress, the basic trends of petroleum exploration at the end of this century are as follows: (1) Of the long-term exploration basins, especially the long-term exploration prospect, new discoveries (referring to newly discovered oil and gas fields and hydrocarbon poly
