Proceeding from the requirement of crack technique,the numerical analysis to the stress state near the notch tip in a impressed-notch sample in three-point bending was conducted.
从裂纹技术的需要出发,对压口试件在三点弯曲模型下其尖端的应力状态进行了数值分析。
2) pressure on the lip of oil seal
唇口压力
3) wellhead pressure
井口压力
1.
The wellhead pressure is low for boosted gas wells.
增压气井井口压力较低, 伴随井筒内积液增多, 采气管柱内的压力损失也加速增大, 然而逐渐减小的环空压力和气体流速已不能有效地将积液举升至地面, 即使按常规气井泡沫排水方法加入泡排药剂后, 靠气井自身能量也无法将井内积液带出井筒。
2.
Wellhead pressure is measured by means of changing the production rate of gas well (or changing production system of gas well).
本文讨论了通过改变气井产量（或称气井工作制度）测取井口压力资料，利用Cullender和Smith计算模型计算井底压力，选用Russell两产量试井分析方法进行资料整理，确定气层平均压力的方法。
3.
In the test of gas well (especially to H T and H P gas well),the maximum closed wellhead pressure is an indispensable parameter that should be measured accurately for selection of production case and gas recovery wellhead and calculation of packer completion technique.
气井 (尤其是高温高压气井 )完井试油时 ,关井最高井口压力对于选择油层套管和采气井口以及封隔器完井工艺的设计都是必不可少的参数 ,必须进行准确预测。
