摘要:
在CO2驱提高油田采收率过程中,经常发生注采管柱断裂失效的现象,严重影响生产及驱油整体效益。通过H2S与CO2复合环境下管柱的预应变和循环加载实验,明确了管材力学性能的衰减规律,并分析了现场生产中对应的实际工况,提出了预防对策。经现场应用,取得了很好的预防效果,管柱断裂频次大幅下降。
Abstract:
In enhancing oil recovery by CO2 flooding,fracture of injection-production string often occurs,seriously affecting the overall efficiency of production and oil displacement. Based on the pre-strain and cyclic loading experiments of the pipe column under the composite environment of H2S and CO2,the decay law of the mechanical properties of the pipe was clarified. The corresponding working conditions in the field production were analyzed,and preventive countermeasures were proposed. After field application,an excellent preventive effect was achieved,and the frequency of pipe string fracture was reduced significantly.
