摘要
JZ20-2油气田产出原油类型复杂,主要为低凝油、黑油和凝析油。利用试验手段,研究了降凝剂对JZ20-2油气田混合原油流变性的影响。通过降凝剂评价试验对降凝剂剂型、处理温度和加剂量进行了优选;通过管输模拟试验对加降凝剂处理后混输原油的降凝效果和稳定性进行了评价。该项研究及其结果对加降凝剂原油输送技术在我国海上的进一步应用有一定借鉴意义。
JZ20-2 oil and gas field produces complex oils, including low pour point oil, high pour point oil and condensate mainly. The rheological property of mixed oil impacted by pour point depressant is studied on basis of tests. Through the evalua tions and tests, the type, treating temperature and the quantity of pour point depressant are optimized. In addition, the effect and stability of pourpoint depressant are evaluated on mixed oil by the simulating test. This study and the results will be useful for further application of pour point depressant in oil pipeline transportation in offshore oilfields.
