1) differential pressure at well head
井口压差
1.
The in-jection wells,pipe network and injection plant in the injection system should be reformed and adjusted and made differential pressure at well head reduce.
根据理论计算,注水站消除泵管压差、提高泵效及管网消除管井压差的节能潜力每年合计约1732×104kW·h,其中井口压差的节能潜力最大,占79。
2) the well bottom to press bad
井底压差
3) drilling pressure differential
钻井压差
4) 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。
5) fracture well head
压裂井口
1.
To the fact of LH-70 model handy fracture well head being easy diapire out,its valve being easy erosion and seal performance not being reliable,analysis and development to its structure has been conducted.
针对LH 70型轻便压裂井口装置四通易刺漏 ,阀体内部易腐蚀 ,以及密封性能不可靠等的实际 ,对其结构进行了分析与技术改进。
6) surface casing pressure
井口套压
1.
Error analysis of stand-pipe pressure control and prediction of surface casing pressure for horizontal well killing process;
水平井压井立压控制误差分析与井口套压预测
补充资料：泵额定压差
分子式：
CAS号：
性质：在泵额定工况下，其额定排出压与额定吸入压力之差。额定压差是泵性能的主要考核指标之一。
