  counter pressure
The obtained solutions are multivalued in a certain range of lengths of the end part and values of the counter pressure.
      
The profiles of rates for the stream of a highly viscous liquid with the ring boundary layer of low-viscous liquid at the cylinder wall and at screw in the both presence and absence of a counter pressure are calculated.
      
Consideration of computer calculations shows that increase in the flow rate is possible when the counter pressure tends to zero and the low-viscous liquid forms a ring boundary layer at the cylinder wall.
      
The influence of counter pressure on electroosmotic velocity and plate number is discussed.
      
The changes of Pcar were induced by applying external counter pressure (Pe) to the neck region of up to ±80 mm Hg; each step of Pe was held for at least 1-2 min.

The source rocks in the Qiangtang Basin, a low thermal flow basin with a paleothermal gradient of about 2℃/100m, are the best ones in Tibet residual basins, where four main source rock formations developed. Analysis of the 7761 samples, collected from the 27 petroleum geology lines in Tibet in 1994-1999, shows that the Xiaochaka Formation, Upper Triassic, is in an over maturity stage and the Middle Jurassic Sowa Formation, Xiali Formation and Buqu Formation are in a middle-late stage of oil generation, and a...

The source rocks in the Qiangtang Basin, a low thermal flow basin with a paleothermal gradient of about 2℃/100m, are the best ones in Tibet residual basins, where four main source rock formations developed. Analysis of the 7761 samples, collected from the 27 petroleum geology lines in Tibet in 1994-1999, shows that the Xiaochaka Formation, Upper Triassic, is in an over maturity stage and the Middle Jurassic Sowa Formation, Xiali Formation and Buqu Formation are in a middle-late stage of oil generation, and a second oil generating process existed in Late Tertiary. All the maturity parameters decrease gradually in cycles from margin to central uplift. The main influential factors of the thermal evolution are: the highest paleo-temperature and the deepest burial depth in relative weak structure in the middle basin; the non-balance pressure in basin margin or nearby fault folder play; the local igneous rock and thermal flow in deep formation.

羌塘盆地是青藏高原残留盆地中石油地质条件相对最好的 ,发育 4套中生界主要海相烃源层 ,属低热流型冷盆 ,古地热梯度一般在 2℃ /10 0m左右。根据对 1994— 1997年 2 7条野外石油地质路线调查获得的总计 7761个样品的热演化的原始分析数据的研究 ,上三叠统肖茶卡组烃源层多处于过成熟阶段 ,中侏罗统索瓦组、夏里组和布曲组烃源层在盆地中部尚处于成熟中晚期生油阶段 ,在新近纪晚期有二次生烃过程。在同一构造或沉积区域 ,纵向镜质组 (或沥青 )反射率平均值随地层埋藏深度的增加而呈半对数线性增加 ,平面上各层烃源层各项成熟度指标都从盆地边缘向中部呈环带状逐渐降低。影响有机质热演化的主要因素有 :①在构造变形相对较弱的盆地中部 ,最高古地温和古埋藏深度起主要作用 ;②盆地边缘或断裂褶皱带附近不均衡压力变形起主要作用 ;③局部地区火成岩及深成地下热流的作用。图 8表 1参 17

Researches on the analytical data more than seven thousands of Mesozoic samples from the Qiangtang Basin in Qinghai-Tibet Plateau show that the Jurassic source rock is still mature and generating oil in the center of Qiangtang Basin.The Jurassic source rock is more and more mature from the center to the margin of the basin.Almost all the T_3x source rocks are highmature to over-mature and the range of oil generation has already very small.The maturity of the organic matters in this basin is mainlly controlled...

Researches on the analytical data more than seven thousands of Mesozoic samples from the Qiangtang Basin in Qinghai-Tibet Plateau show that the Jurassic source rock is still mature and generating oil in the center of Qiangtang Basin.The Jurassic source rock is more and more mature from the center to the margin of the basin.Almost all the T_3x source rocks are highmature to over-mature and the range of oil generation has already very small.The maturity of the organic matters in this basin is mainlly controlled by the palaeo-geotemperature,the degree of tectonic deformation and pyrogenetic rock and plutonic hot fluid.In the center and the east of the basin,the main influential factor of organic matter's maturation is the maximum palaeo-geotemperture or palaeoburial depth.Near the fault or folded zone in the basin and the margin of the basin,organic matter's maturation is mainlly affected by the strongly unbalanced pressure.And in the west of the basin,the plutonic hot fluid in the basement fracture zone may be the main influence factor of organic matter's maturation.There are two(or three) hydrocarbon-generating processes occurring in the Late Jurassic-Early Cretaceous and the time of Tertiary sedimenting.In particular,the hydrocarbon-generating process caused by the Jurassic source rock in the Early Miocene to the Late Miocene is more favorable to the petroleum exploration in this basin.

对青藏高原羌塘盆地中生界7 000多块样品的分析数据进行筛选和综合研究可知,侏罗系烃源岩在羌塘盆地中部尚处于成熟生油阶段,向四周成熟度逐渐增高;上三叠统肖茶卡组烃源岩几乎全部处于高成熟—过成熟,成熟生油范围已经很小。羌塘盆地有机质成熟度主要受古地温、构造变形程度和火成岩及深成热流的控制。盆地中部及东部主要受最高古地温或最大古埋藏深度的影响;盆地断裂或褶皱带附近及其盆地边缘主要受强烈不均衡压力的影响;而在盆地西部,基底断裂带的深成地下热流可能是主要影响因素。盆地中部具有2次(或3次)主要生烃过程(侏罗纪晚期—白垩纪早期与第三系沉积时期),特别是新近纪中新世早期至中新世后期,侏罗系烃源层的生烃过程对油气藏勘探更为有利。
