海洋石油开采过程中由于工况条件不稳定,紊流过程中常常夹杂有断塞流,且单井产量浮动大,气、油比范围宽,重油粘度大且夹杂气泡,难以分离等特点,因此给连续稳定计量带来困难.原油采出后在海洋石油生产平台短暂停留后即通过海管输送至其他油田实现贸易交接.根据国家标准GB 50350-2005中规定,含水原油计量属于三级计量,精度应在±5%以内.本文通过优化常规计量装置的设计并系统集成,研究了基于GLCC(柱状
吴XX井区长X层位大规模的致密油藏的有效开发,需要测井评价构建(优选)测井属性参数系统表征致密油层的有效性,为选取有效的试油层段提供技术保障.围绕致密油层“六性”关系中与储层品质有关的评价,在“六性一孔隙结构”特征研究的基础上,优选出储层的物性参数、孔隙结构参数、含油性参数、储能指数等参数,在孔隙结构评价的基础上,建立了致密油层六元系数分类法,结合油层的压裂试油产量,建立了致密油层测井分类评价标准

中尺度涡在中国南海海域广泛分布,研究南海中尺度涡有助于更好地了解中尺度涡对大洋环流以及对中国气候所带来的影响.本文首先针对南海海域中尺度涡的自动识别方法开展研究,进而获取南海海域中尺度涡的时空分布与演变等特征.
The highest concentration of ozone exists in the tropical stratosphere, thus, the tropical total column ozone (TCO) change would affect global ozone distribution through dynamic transport.
We investigated temporal and vertical structure variations in the capacity of the low-level Somalia Jet (SMJ) to transport moisture from the Southern to the Northern hemisphere in boreal summer during
Observational studies have pointed out that the extreme winter storms of 2007/2008 in China were most closely associated with the third leading mode (LM3) of the East Asia Winter Monsoon (EAWM).We inv
