Study of reliability engineering of well head equipment in China

我国 井口 装置的现状及可靠性研究的必要

When the pressure needed in treatment is higher than working pressure of well head equipment a new type of protector against damage and erosion in short time for fracturing operation has been designed .

当酸化压裂所需的压力高于 井口 设备的工作压力，为保护 井口 设备不被短时间酸压作业损坏或腐蚀，设计一种结构新颖的井口保护器。

Develoment of CAD software for well head equipment

井口 装置CAD软件开发

Well head equipment damage analysis of well xin & 851

新851井 井口 装置受损情况分析研究

The reformed one has a feature of reasonable structure high antifriction and reliable safety which are the first well head equipment to be taken in fracture operation .

改进后LH70型轻便压裂井口结构合理、耐磨性提高、安全性能可靠，成为压裂施工中首选的 井口 装置。
