油井

By analyzing the production test data,we get the index production equation,binomial production,production degression equation and the single well control reserve.

通过分析该区的试采井资料，得到了指数式产能方程、二项式产能方程及油井产能递减方程，同时计算了单井控制可采储量。

Power-law fluid is used to describe the Non-newtonian rheological property of the produced fluid in a polymer-driving well; the governing equations, boundary and initial equations of power-law fluid in eccentric annuli with the inner cylinder reciprocating axially is established in bipolar coordinates system; formulas of instantaneous flow rate and stress distribution on the outwall of the inner cylinder of the unsteady flow of power-law fluid in eccentric annuli with the inner cylinder reciprocating axially are established.

在理论上，用幂律流体模型描述了聚合物驱油井产出液的非Newton流变性；建立了双极坐标系下幂律流体在内管做轴向往复运动的偏心环空中非定常流的控制方程及边界条件和初始条件方程；建立了双极坐标系下幂律流体在内管做轴向往复运动的偏心环空中流动时瞬时流量和流体在内管壁上的压力分布计算公式。

On the base of wellbore fluid analysis, the math model, which decided the annular air bleeder's reasonable operation rules, has been established, which can guide the oil well production.

并在井筒流体分析的基础上，建立了确定环空放气阀合理工作制度的数学模型，用于指导油井的生产。

Hot washing by moving hot washing truck and hollow sucker rod is efficient, less in washing fluid , no formation contaminant, no casinghead gas release. It adapts oil wells with low reservoir pressure and deep depth of plunger and serious paraffin problem.

活动热洗车配合空心抽油杆热洗清蜡热效率高、洗井液少、不伤害油层、不用放套气，适合于地层压力低、下泵深度较深、结蜡严重、常规洗井困难的油井。

One of the real-time parts of this BI chain is well data.

这个BI链上其中一个即时的部份就是油井资料。

At present there are two methods measure the moisture rate: one is a chemic method.

当前油井下原油含水率的测量缺乏快速可靠的技术手段。

High strength and high chrome steel for oil well tubing is a kind of material difficult to machine.

高强度高Cr钢油井管材料属于切削加工中的难加工材料，加工技术要求高。

For oil drilling, oil and gas wells in the circulation rotary drilling mud to increase agent, cooling the bit, cutting away material from the debris, lubricating the drill pipe, closed hole wall, oil and gas pressure control to prevent the oil from the spray.

用于石油钻探，油气井旋转钻探中的环流泥浆加重剂，冷却钻头，带走切削下来的碎屑物，润滑钻杆，封闭孔壁，控制油气压力，防止油井自喷。

So how to make it durable and economical is our purpose - optimization of casing size and coadjutor layout.

固井是油井建井过程中的一个重要环节，而套管设计又是其中的一个关键问题，如何让其满足强度要求而又尽可能的经济，即追求套管尺寸和扶正器布局的最优化是我们最追求的目标。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
