- pressure drawdown profile 压降剖面
- By the pressure behavior, the pressure drawdown curve may be divided into three phases, namely nonsteady state, transit state and pseudosteady state. 根据压力动态,压降曲线可以划分为非稳态、过渡和拟稳态三个阶段。
- Due to the development of Taipei City, extensive pumping to supply water for the city caused the groundwater pressure drawdown and resulted in excessive ground subsidence. 随着台北都会之发展，人口成长与用南量增加等因素，大量凿井抽水使地下水位急速下降，并导致地盘沉陷。
- Then a differential model,which discribes the changes of sandface flow rate under pressure drawdown and buildup is derived.The rate model is used to solve the question ... 通过非结构网络 ,把井眼看作一个网格块 ,推导出了能反映开、关井后地层渗流量变化的用于求解单相流试井问题的差分模型。
- The water lock also is the major feature of two-phase flow in porous medium.In heterogeneous model, gas recovery can be enhanced by reducing gas pressure or raising drive pressure drawdown. 同时，水锁也是多孔介质中两相渗流的主要特征，可以通过降低压力使气体充分膨胀和提高驱替压差来提高采收率，降低封闭气量。
- Following long-term waterflooding,the sandstone reserv oir has variable spontaneous poten-tial(SP)resulted from variable electrofilt ration potential which is closed with the pressure drawdown. 经长期注水开发的砂岩储集层,自然电位的变化主要由过滤电位的变化所引起,而过滤电位与压差密切相关,由此引出了应用自然电位解释孔隙压力方法。
- Meanwhile,the pump setting depth can be deepened,producing pressure drawdown can be increased,crude output and economic benefit can be improved by using conventional tubing,rod ... 利用常规的管、杆、泵、抽油机,可以大幅度加深泵挂,放大生产压差,增加原油产量,提高经济效益。
