| 3. | It sells more than 2 . 5 million barrels a day and is believed to have about 10 percent of the world ' s proven reserves 它每天出售250多万桶石油,据信约拥有世界已探明石油储量的10 。 |
| 4. | Two relation models between the drill footage and proved reserves are introduced : gompertz model and exponential model 摘要为估算油气探明储量,介绍了探井进尺和探明储量间的2种统计模型:龚帕兹模型和指数模型。 |
| 5. | Ethiopia / ' s proven reserves of oil and gas are minimal but analysts believe there is potential , particularly for gas , in the ogaden 埃塞俄比亚已探明的石油和天然气储量很少,但分析人士认为,欧加登地区有很大开发潜力,特别在天然气方面。 |
| 6. | The world ' s proved reserves of oil and gas rose just 2 per cent to 257 . 7bn barrels , while production increased 1 per cent to just shy of 19bn barrels , the authors of the study , john s 该研究的作者发现,全球已探明油气储量仅上升了2 % ,至2577亿桶,而产量增加了1 % ,接近190亿桶。 |
| 7. | Companies also have a stake in exaggeration , as in the recent case of the royal / dutch shell group , which admitted that its “ proven reserves ” were 20 percent less than originally stated 石油公司本身也参与这样的夸大行为,最近的例子是荷兰皇家壳牌石油集团承认其确定蕴藏量比当初宣称的数字少20 % 。 |
| 8. | The municipality has 49 kinds of minerals with proved reserves and 218 mineral deposits , and the main minerals include coal , lead , zinc , copper , iron , tungsten , antimony , cement limestone and granite , of which 35 kinds rank top three and 23 kinds top one in the province 全市已探明储量的矿产49种,矿床218个,主要矿种有煤炭、铅、锌、铜、铁、钨、锑、水泥灰岩、花岗石等,其中保有储量位居全省前三位的有35种,居第一位的有23种。 |
| 9. | Up to 60 % ~ 70 % oil and gas proved reserves is in low permeability formation in recent exploration with 5000 x 1012m3of gas , and most of gas reserves are located in tarim and erdos basin , which are the main resource of " west gas to east " project . in order to meet the national energy strategy , the key issue is to develop the tight gas fields with high efficiency and profit 在近几年探明的油气地质储量中,低渗透油气储量所占探明石油和天然气地质储量中的比例高达60 70以上,低渗气藏储量达到5000 10 ~ ( 12 ) m ~ 3 ,占总储量的20左右,且大部分低渗气藏储量都处在长庆和塔里木等西气东输的主战场,因此,就面临着如何高效开发低渗气藏的问题。 |
