摘要
河南魏岗油田原油的主要特点是高含蜡（45．1％～48．0％）、高凝固点（46．0～47．0℃）和低含硫。油藏埋藏深，地层条件下原油粘度低，属于高凝油油藏。通常把含蜡量在8％以上的原油称为高蜡油。在开发过程中，通过矿场试验、数值模拟及实际温度监测，探索出一套高效开发这类油藏的方法，认为对这类高凝油油藏应采用常规注水开发，井筒防蜡降凝就可以了。
The crude in Weigang oilfield is characterized by high wax content(45. 1%～48. 0% ), high pour point (46. 0～47. 0℃) and low sulfur content, with deeper burial and low viscosity under reservoir conditions. Based on field test, numerical simulation and actual temperature monitoring, a set of method for effectively developing such reservoir was explored. The author proposed that conventional waterflood is feasible, supported by paraffin inhibition and pour point reduction in wellbore.
