渤海湾盆地沙南凹陷BZ油田沙一段生屑云岩主力含油储层投产后,发现实际生产特征与初始地质认识吻合度差,部分区块可能具有增储上产的潜力。通过利用油田生产动态资料,主要包括压力、产量及PVT实验等数据,采用广义物质平衡计算法识别出A4井区滚动勘探潜力最大。在此基础上,精细刻画生屑云岩沉积期古地貌和古生态环境特征并结合生屑云岩发育规律,预测了A4井区生屑云岩储层新的空间展布范围。实际钻探结果证实了储层预测的准确性,新增探明储量近400万t,保障了BZ油田的可持续发展和投资效益。该套方案对国内海上相似地质条件油田的滚动勘探开发具有借鉴意义。  相似文献

Ocean circulation in the Yellow and East China Seas is very rich in mesoscale phenomena, such as eddies, fronts, upwellings, river plumes, etc. Among others, having drawn tremendous attention from oceanographic community in the past for nearly 50 years are mainly the Yellow Sea Cold Water Mass (YSCWM) and its related circulation, the Yellow Sea Warm Current (YSWC), the East China Sea  相似文献   

Influence of the Choice of Core-Envelope Transition Point on the Binary Merger of Two Main-sequence Components

We have studied the influence of different choices of core-envelope transition point on the final merger of contact binaries with two main-sequence components. A binary of 1.00 + 0.90M⊙ with an initial orbital period of 0.35d is examined. The mass fraction of the primary mixed with the matter of the secondary, qmix, determined by the chosen core-envelope transition point, ranges from 0.04 to 1.00 in our analysis. If as qmix< 0.8, none of the  相似文献   

Geochemical survey of thermal system in Northeast China and their geothermometric characters

The chemical composition of several thermal springs around Changbaishan area has been investigated. Cenozoic basaltic rocks are widely distributed in Northeast China and geothermal characteristics have been described. About one hundred hot springs exist around Changhaishan Volcano at the border between China and D.P.R.Korea with high temperature about 82~C. The pH values of the spring water range from 6.9 to 7.1 and the total flow rate is about 4.8 L/sec. The chemical composition of the thermal springs is sodium carbonate; the high-mineral contents of thermal water are believed to have medicinal properties. Bathhouses are already built along the hot springs to take the advantage of the supposed healing properties. The high quality of those hot springs is believed to be utilitized for mineral water. The chemical equilibrium temperatures were estimated at about 160℃ based on the Na-K-Ca geochemical thermometer.  相似文献   

Size-Flux Relation in Solar Active Regions     

O.V.Chumak 《中国天文和天体物理学报》2003,3(2):175-182

We present a study of the relationship between integral area and corresponding total magnetic flux for solar active regions. It is shown that some of these relationships are satisfied to simple power laws. Fractal examination showed that some of these power laws can not be justified inside the simple models of stationary magnetic flux tube aggregation. All magnetic fluxes and corresponding areas were calculated using the data measured with the Solar Magnetic Field Telescope of the Huairou Solar Observing Station in Beijing.  相似文献

不同景观条件下机械剥蚀与化学剥蚀间之比     

А.П.杰德科夫  В.И.莫兹执林  А.Н.沙里福林  宋广生  李秀英 《地理科学进展》1985,4(4):1-7

机械剥蚀和化学剥蚀的数量是地形形成变化的主要指标,早在上一世纪末就已开始对其进行定量评定。通常,评定剥蚀的基础是离子径流和悬移泥沙径流。当认为这种方法是最客观和最精确时,还必须指出其极大局限性,这种局限性首先是由于机械剥蚀物和化学剥蚀物的形成与搬运的不同机制的缘故。  相似文献   

死海（约旦）里散半岛的重磁勘查     

Batay.  A Zoubi  AA 《长春地质学院学报》1996,26(1):71-77

里散半岛位于非洲板块和阿拉伯板块交接处的死海盆地中。该盆地面积大，构造简单且有下沉运动，说明它是一拉张型盆地。由重力异常数据发现死海盆地可划分成沿南北延伸各约３０ｋｍ长的几个块体，里散半岛是其中最深的一个。中生代沉积厚度约６ｋｍ，更新世沉积厚度为９ｋｍ。死海盆地的拉张距离为２０ｋｍ，表明死海盆地的年龄约３．３Ｍａ。里散半岛下部的前寒武纪结晶基底磁化率较高，这与区内延续的构造活动性有关。  相似文献

通常,经济区划的任务包括以下几个主要阶段:1) 确定作为基础区的地域;2)按照基础区选择区划指标系统及其定量评价;3) 选择区域系统模式;4) 阐明课题建立算法,直接把基础区进行分类计算;5)解释已获得的结果,选出最好的区划方案和有关进一步改善工作方法的结论等等。基础区的范围视所要解决的任务性质而定。  相似文献
