钻杆套管两用动力钳的研制及应用

为了提高原钻杆动力钳的使用效率,在其上增加套管钳功能,实现一钳两用的目的,研制了钻杆套管两用动力钳。该动力钳是在原钻杆动力钳的基础上增加套管动力钳功能。设计了上、下钳间隙调节气缸,使其性能参数能满足钻井及下套管施工需求。在两用动力钳上安装的扭矩控制记录仪,可测量、显示、记录和控制钻杆上扣时扭矩,以保证钻杆、套管上扣时的最佳拧接扭矩。在大庆油田的推广应用中,该动力钳均收到较好的应用效果。由于受结构尺寸的限制,该两用动力钳不适用于大于φ203.2mm的套管。

机械零件的模糊可靠性

简述了模糊可靠性理论产生的必然性，给出了模糊可靠性、可靠性模糊子集及模糊故障等基本概念。模糊可靠性的主要指标有模糊可靠度R、模糊故障率λ和模糊平均寿命MTTF。在应用方面，对机械零件疲劳强度的模糊可靠性设计、轴类零件刚度的模糊可靠性设计和滚动轴承的模糊可靠性寿命计算等问题作了讨论。推出了模糊可靠度的计算式，可根据可靠度的大小判断零件设计是否合理或在给定模糊可靠度的条件下确定零件尺寸。机械零件的模糊可靠性优化设计与一般可靠性优化设计类似，求解的基本途径是将其转化为一般性优化问题，然后按常规优化方法求解。     

抽油机自适应控制节能器研制

油田开发后期油井供液量不足，造成抽油机的抽空和机械磨损，为此，利用单片机系统通过实时检测抽油机电压、电流及其相位差，建立相应的功率因数曲线，采用自适应优化机制，动态调整启停机时间，实现抽油机的运行时间随油井的液量变化而变化。在保证油井产量的前提下，实现抽油机工作效率的最优化，达到节能降耗的目的，现场应用显示，系统节能效果良好。     

自升式修井平台升降装置强度安全可靠性分析

借助有限元分析软件，以“胜利作业三号”自升式修井平台起升系统的重要部件－－齿轮齿条传动装置为研究对象，计算了起升系统在3种作业状态下的接触应力和弯曲应力，完成了传动装置的接触疲劳强度、弯曲疲劳强度以及弯曲静强度的安全性校核，并在此基础上进行了概率可靠性分析。计算分析得出的结论对平台的设计、制造和管理具有一定的指导意义。

Increase in the operating reliability of a well sucker-rod pump

Problems are considered that arise in strengthening cylinders and plungers of well sucker-rod pumps. The advantages and disadvantages are analyzed for methods of nitriding and chromizing in order to provide cylinder wear resistance. New efficient strengthening technology is proposed, i.e., multistage ion-vacuum nitriding, whose introduction has made it possible to increase the reliable operating life of pumps under complicated oil recovery conditions.     

Simulating strength, reliability, and viability for damaged structural elements

Research has been done on estimating and providing viability in machines and equipment on the assumption of the essential scope for safe operation for a certain time employing damaged components. The approach enables one to handle various tasks with a precision sufficient for engineering practice that arise in designing and operating constructional elements having hypothetical or actual defects and damage and operated under standard or emergency conditions. __________ Translated from Khimicheskoe i Neftegazovoe Mashinostroenie, No. 1, pp. 37–42, January, 2007.
