一、石油普查的趋向 近十年来,石油普查趋向于超速发展,世界石油工业的原料基地增长急剧,油气燃料所占比重日益增加,天然气利用发展迅速。以1961年计世界煤产量为21亿吨,原油11.6亿吨,天然气达5900亿立方米;石油天然气能量的利用已超过了煤的利用。油气资源增长的主要途径是:扩大普查范围,开拓新的含油气区域和开展浅海陆棚、边远地区的资源调查,这些都收到了成效,其中大油气田的发现和开拓是后备产量和储量增长的重要因素;其次钻探较深层的油气藏,
First, the trend of oil census The past decade, the petroleum census tends to speeding up, the world’s oil industry, the rapid growth of raw materials base, the proportion of oil and gas fuel is increasing, the rapid development of natural gas utilization. In 1961, the world’s coal production was 2.1 billion tons, crude oil 1.16 billion tons and natural gas reached 590 billion cubic meters. The utilization of oil and natural gas energy exceeded the utilization of coal. The main approaches to the growth of oil and gas resources are: to expand the scope of the census, open up new oil and gas areas and carry out resource surveys in shallow sea shelters and remote areas, all of which have yielded results. The discovery and development of large oil and gas fields are a result of reserve production and reserve growth Important factors; followed by drilling deeper oil and gas reservoirs,
