查询词典 artesian well

Along with horizon development well to implement, some problem became more and more gravity, such as sandbody'scale and sandbody'boundary was uncertainty and layer pressure was uneqilibrium for different well area development degree is not community. These taked a few difficulty of comprehensive evaluaterating, deploying horizon development well, adjusting well trackway for the gas field, and it might take any geologic risk.

随着该气田水平开发井的逐步实施，其含气砂体规模及砂体边界的不确定性以及由于各井块开发程度的不均一性而导致的地层压力不均衡等地质难题都日益显现出来，这些都给该气田的全面评价、水平开发井部署和井轨迹的调整带来困难，并可能引起更大的勘探开发风险。

Any given oil well has a finite supply of oil, and the wells' production follows the shape of a bell curve. Extracting oil is cheap and easy on the curve's upslope but after the the well has peaked – the point at which half of the well's oil has been extracted – production becomes more difficult and expensive. The output of the well begins to decline and will never recover; production falls steadily and the cost to extract the oil rises.

由於任何一个油井都只有固定的供应量，因此每个油井的原油产量都会遵循钟型曲线：一开始汲取原油很便宜也很容易，因此曲线是上升的，但当油井的产量到顶之后–也就是油井中的原油存量已被汲取出一半时–原油的生产就会变得愈渐困难且昂贵，油井的输出产量也开始下降，而且再也无法恢复，所以产量也将持续减少、使得生产成本不断增加。

Exchange the heating well and the oil extraction well that the much more above-mentioned well electricity heat the oil shale retorting mine, continue to heat to mine. 5 after years, the temperature that is apart from to heat the or so place of 6 meters of well is also only is 500°C, but heat whole temperatures of the nearby rock strata of wells all very high, cause the calories follow the peripheral rock strata in great quantities lost.

2将上述多井电加热油页岩干馏开采的加热井与采油井交换位置，继续加热开采。5年后，距加热井6米左右的地方温度也仅为500℃，而待采油页岩层与邻近地层的接触面处整体温度很高，说明在整个开采过程中油页岩层向邻近地层散失了大量的热。

The ratio of the well-testing data is used and the reliability of the analysis results can be also increased. The well pressure of a swabbing producing well can be calculated with this new model as well.

同时，利用该理论还可计算抽汲过程中任一时刻的井底压力和关井时刻的井底压力，解决了抽汲井难以计算关井时刻井底压力的问题。

The analysis result shows that Kun 2# well and its vicinities is the beneficial oil-gas bearing province in Kunyite depression, and the sealing of Kun 1# fault zone is well, and the well wall in Kun 2# well region is relatively stable.

分析结果显示，昆2井及其附近地区为该凹陷的有利成藏地区，且昆1断裂带的封闭性较好，昆2井地区井壁较为稳定

The invention discloses a high-voltage N-type metal oxide semiconductor, including a P-type substrate, a P-well drift region and an N-type drift region are arranged on the P-type substrate, a P-type contact hole, an N-type source and a field oxide layer are arranged on the P-well, an N-type drain and the filed oxide layer are arranged on the N-type drift region; the invention is characterized in that the thickness a grid oxide layer part which is positioned above the P-well is smaller than the grid oxide layer part which is positioned above the N-type drift region and a thin grid oxide layer and a thick thin grid oxide layer are respectively formed accordingly, a P-type impurity injection region is arranged in the P-well, and the P-type impurity injection region is positioned below the thin grid oxide layer.

本发明公开一种高压N型金属氧化物半导体管，包括P型衬底，在P型衬底上设有P型阱和N型漂移区，在P型阱上设有P型接触孔、N型源及场氧化层，在N型漂移区上设有N型漏及场氧化层，其特征在于位于P型阱上方的栅氧化层部分的厚度小于位于N型漂移区上方的栅氧化层部分并由此分别形成薄栅氧化层和厚薄栅氧化层，在P型阱内设有P型杂质注入区且该P型杂质注入区位于薄栅氧化层的下面。

Drilling time will be lasted and lateral force on casing exerted by drill pipe will increase in case of drilling deep well, ultradeep well, high inclined hole, extended reach well and horizontal well, therefore, friction and wear between casing and drill pipe became a severe problem.

在深井、超深井、大斜度井、大位移井及水平井中，钻井时间延长、钻柱作用在套管上的侧向力增高，因此套管和钻柱的摩擦与磨损问题越来越突出。

ABSTRACT Drilling time will be lasted and lateral force on casing exerted by drill pipe will increase in case of drilling deep well, ultradeep well, high inclined hole, extended reach well and horizontal well, therefore, friction and wear between casing and drill pipe became a severe problem.

钻杆接头与套管摩擦磨损问题的理论与试验研究套管磨损

The results show that the water breakthrough time shortens with the increase of the horizontal well length. Under the same well space and production conditions, the water breakthrough time of five-spot pattern is longer than that of seven-spot and nine-spot pattern. With the increase of angle between the horizontal well and the horizontal direction, the water breakthrough time shortens in five-spot well pattern, firstly increases and then decreases in seven-spot pattern, and increases in nine-spot pattern. The influence of reservoir and fluid parameters on the water breakthough time is little.

计算结果表明，井网的见水时间随水平井长度的增加而缩短；相同的井距和生产条件下，五点法井网的见水时间要长于九点法和七点法井网；随水平井与水平方向夹角的增大，五点法井网的见水时间缩短，七点法井网的见水时间先增加后缩短，九点法井网的见水时间增加；油藏和流体参数对井网见水时间影响不大。

This matter overthrew all basises I learned from Sunday school .

这件事把我从周日学校学到的所有道理都颠覆了。

It's one of the cruel ironies of aging: if you want to remember your favorite restaurants, the less you should eat at them.

这是一个老化的残酷讽刺：如果你想记住你最喜欢的餐馆，你应该更少吃到它们。
