摘要:
为了降低生产流体在井筒中产生的压降、充分利用积液气井自身能量进行低成本排水采气，研制了喷射旋流复合排液工具。在设计喷射旋流复合排液工具结构的基础上，研制了其性能测试试验系统，测试了不同气体流量下放置不同结构参数该工具时的模拟井筒压降，开展了结构参数的单因素分析和正交试验分析，得到了不同条件下喷射旋流复合排液工具最优的结构参数。研究结果表明，喷射旋流复合排液工具的主要结构参数均会影响流体在井筒中产生的压降；要使井筒中的压降最小，不同产量的气井对应不同结构参数的工具。结构参数优化后的喷射旋流复合排液工具在西南地区M气田A井进行了现场试验，在相同生产周期内，累计产气量平均增加20.95%，累计产水量平均增加21.59%，验证了该工具的排液增产效果。研究和现场试验表明，喷射旋流复合排液工具为积液气井低成本排水采气提供了一种新的技术手段。
Abstract:In order to reduce the pressure drop of production fluid in the wellbore and make full use of the energy of gas wells with fluid accumulation for low-cost drainage and gas recovery, a jetting and helical combination drain tool was developed. Based on the design of the tool structure, the performance test system of the tool was built.The simulated wellbore pressure drops at different gas flow rates with different structural parameters were tested, and the single factor analysis and orthogonal test analysis of the structural parameters of the tool were carried out. In addition, the optimal structural parameter combinations of the tool at different conditions were obtained. The results show that the main structural parameters of the tool affect the pressure drop of the fluid in the wellbore. Moreover, gas wells with different production rate require tools with different structural parameter combinations to minimize the wellbore pressure drop. After the optimized tool was run in Well A, the cumulative gas production increased by an average of 20.95%, and the cumulative water production increased by an average of 21.59% over a same production period. The drainage stimulation effect of the tool was demonstrated. The successful application of this tool provides a new technical method for low-cost drainage and gas recovery in gas wells with fluid accumulation.
