In the light of the problems with imported offshore wellhead, such as being bulky and expensive and being inconvenient to mount and maintain, Model HKY65―21 offshore wellhead is developed. This wellhead consists of tubing head assembly, PHK plate gate valve, safety valve, stop valve, clamp, small four-way connection and choke, and it is small-sized, light-weighted, high-strength, corrosion- and abrasion-resistant, reliably sealed and convenient to mount and maintain. Application shows that the wellhead can satisfy the requirements of offshore production with good performance.

针对海上油田所用国外采油井口装置存在体积庞大笨重、价格昂贵以及与国产设施不配套和安装维护不便等问题，研制了HKY65―21型海上井口装置这种井口装置主要由油管头总成、PHK平板闸阀、井口安全阀、截止阀、卡箍总成、小四通和节流器组成，具有体积小、重量轻、强度高、防腐耐磨、密封可靠和安装维护方便等优点现场使用128套的实践表明，其各项技术性能指标均能满足海洋石油生产的要求，完全可以取代进口产品，经济效益可观

And oil field sucker rod coupling of production and export.

及油田抽油杆接箍的生产，外销。

The visco?-elastic fluid hydrodynamic theory was applied to the wear-resistance experiment on sucker rods.The values of normal stress in suck string generated by visco?-elastic fluid and eccentricity brought out by sucker string were measured quantitatively.The partial abrasion of sucker string and tube in oil well was caused from the normal stress of visco?-elastic fluid.A module for bending analysis of sucker rod in cross direction and wire direction was developed.

大庆油田实施聚合物驱油以后，出现了抽油杆受力状况恶化、抽油杆柱严重偏磨的现象，为此开展了粘弹性流体水动力学理论和试验研究，得出了粘弹性流体在抽油机井筒内的流动规律及对抽油杆柱法向应力的影响规律，定量测出了粘弹性流体对抽油杆柱的法向应力值和抽油杆柱产生的偏心率。
