油层解堵剂的室内试验研究

The testing study of reservoir plug removal agent in the lab

随着人们对油气层认识的不断深入 ,研究者越来越重视油气层损害与保护问题。油气层损害包括无机损害和有机损害。根据交二块油层损害特点 ,研制出有机解堵剂JD— 99。JD— 99对胶质、沥青质和蜡质等有机堵塞物具有很强的解堵能力和分散能力 ,并对原油具有一定的降粘作用。

The questions of reservoir damage and reservoir protection are paid great attention.Reservoir damage includes inorganic damage and organic damage .In the paper,an organic plug removal agent JD 99 has been developed on the basis of the damage features of Jiao 2 stact reservoir.JD 99 has strong plug removal and dispersion ability to colloid,asphaltenes(ASPH) and paraffin etc.,it has viscosity reducing effect to crude oil.The testing study result and two ways of field application are presented in the paper.
