酒西盆地单北油田下第三系火烧沟组砂岩油藏长期以来被认为是水动力圈闭油藏的范例。
The influence of percentage of gas in oil, slope of side plate, effective bulk modulus, and centrifugal force and gear pair vibration on trapped oil pressure is studied by numerical simulation.
采用数值模拟方法研究了含气比，侧板倾斜，有效体积模量，离心力和齿轮副的振动等因素对困油压力的影响。
The simulation model of the trapped oil pressure is established in the paper, and the model is divided into static model and dynamic model according to with or without dynamic factor of gear pair.
依据模型中是否考虑齿轮副的动力学分析，将困油模型分为静态模型和动态模型。
When the well reaches a pool, oil usually rises up the well because of its density difference with water beneath it or because of the pressure of expanding gas trapped above it.
当井和一个水池相接时，油通常会从井里上升，因为它与井下的水的密度不同，或者因为停留在它上方的膨胀气体的压力。
Given an accurate map of the rock under the ground, geologists can recognise places where oil may be trapped.
鉴于一个在地下岩石准确的地图，地质学家可以识别在对石油可能被困的地方。
For the light to be trapped in two dimensions, the object's surface needed to be smooth enough to cleanly reflect most of the light into the oil layer rather than scattering it at all angles.
要把光被捕获在两维的曲线状表面上时，要求物体表面非常平滑，才足以把大部分光线干净利落地反射进油层而不是分散在所有的各个角度上。
Oil companies use CO2; once pumped down, it is trapped there.
石油公司一般使用二氧化碳，一旦被打入井下，二氧化碳便会留在井底。
Coast Guard officials say tests show the oil is BP's, but it's considered dead oil that's been trapped on the Gulf floor, not fresh oil that is seeping from the plugged well.
美国海岸警卫队的官员称，测试结果显示该石油来自英国石油公司，但是那是陷入墨西哥湾底部的死油，并不是从密封的井中渗出的新鲜石油。
They were surprised to learn that ocean currents trapped mixtures of oil and bubbles in plumes about 300 metres above the seabed.
然后他们惊奇地发现，在海底上方约300米处，洋流把石油与气泡的混合物一缕一缕地包裹了起来。
This causes air bubbles to be trapped in the oil creating foam.
这将导致气泡将被困在石油创造泡沫。
Indeed, since the Louisiana berm will not be continuous, there is a strong likelihood that oil will flow in through the gaps, then possibly become trapped in wetlands.
实际上，由于路易斯安纳的沙堤并不连续，石油很有可能从缺口流入，并停留在湿地中。
