摘要:
 

高凝油井在常规试油过程中，原油易结蜡且流动困难，无法达到试油求产目的。利用Wellflo软件模拟分析注入流体温度、下泵深度、泵压

及泵入量的变化对井筒温度分布的影响，优选水力泵排液的施工参数，配合地面流程加热及保温技术，完成了大庆油田AA区块A1井等3井次的试油测试，施工中动力液

采用温度70℃的热水，井口温度及日产油量平稳，落实了储层的液性和产能。现场应用表明，高凝油井水力泵排液参数分析及优化可减少工具起下次数，防止井筒发生

析蜡凝固，降低能耗损失，为高凝油井试油及求产提供了借鉴。

Abstract:
 

When conventional oil testing is conducted in high pourpoint oil wells, crude oil may

wax and flow difficultly, failing to meet the purpose of oil test and production. In this paper, the Wellflo software was used to simulate and

analyze how the changes of injected fluid temperature, pump landing depth, pump pressure and pump rate affect the wellbore temperature

distribution. Based on the optimal discharge parameters of hydraulic pump, as well as the surface process heating and isolation technology, the

oil testing was completed for 3 wells (including A1) in AA block of Daqing Oilfield. During the operations, the 70℃ hot water was selected as the

hydraulic fluid, the wellhead temperature and daily oil production were stable, and the liquid potential and productivity of the reservoir were

determined. The field application shows that the analysis and optimization of discharge parameters of hydraulic pump in high pourpoint oil well

can help reduce the number of tripout, prevent wax solidification in the wellbore, and reduce the energy consumption, thereby providing

reference for the oil testing and production of high pourpoint oil wells.
