摘要:

塔河油田为碳酸盐岩超深、超稠油油藏,因油稠配合掺稀生产,有杆泵举升主要以针对稠油掺稀设计的液压
反馈式抽稠泵为主。对液压反馈式抽稠泵在掺稀井中的受力情况进行分析,并对各种载荷的构成因素进行敏感性评
价,得出动液面及混合液黏度是影响载荷的最敏感因素。在受力分析的基础上,找出了目前杆柱设计方法存在的问
题,并对杆柱断脱原因进行了分析。通过大量实测及计算数据对比,得出优化后杆柱受力计算误差更小、受力状况评
价更加准确的结论,应用优化后的计算方法,计算出目前各种机杆泵组合情况下的最大抽深,用于指导生产管理。

Abstract:

Tahe Oilfield is a carbonate reservoir with ultra-deep,ultra-heavy oil,which needs to mix with light oil. Sucker rod
pumps are mainly the hydraulic feedback heavy oil pump,which is designed specifically for heavy oil production. The stress
situation of hydraulic feedback heavy oil pump in mixing light oil wells was analyzed,and the sensitivity of various loading
factors was evaluated,and finally we put forward that producing fluid level and viscosity of the miscible liquids are the most
sensitive factors affecting the loading. On the basis of force analysis,we identify the problems of rod string designing method
at present and analyze the reasons of the rupture and out of joint of the sucker sod. Through a lot of comparison of the measured
and calculated data,we draw the conclusion that the stress error of optimized poles is smaller and the stress status evaluation is
more accurate. The optimized calculation method will be used to calculate the maximum pump depth for various combinations
of the oil extractor,rod and pump,and to guide the production management.
