| 摘 要： | 流花11-1油田储层岩心的润湿性,经作业者测定结果是亲油的。本文以该油田原油的极性组分在纵向上的变化为依据,用相对渗透率曲线鉴定润湿性的方法,最后判断流花11-1油田的润湿性是非均质的,即上油层段亲水,下油层段亲油。同时讨论了流花11-1油田4号井油基泥浆取心液对该井岩心的污染,使原亲水的上油层段岩心变成亲油的假象。

| Abstract: | The wettability of reservoir cores of Liuhua11-1 oil field is oil-wet by operator's determination. Based on the longitudinal variation of polar component of crude oil, the method of determiningwettability using relative permeability curves was used to determine that the wettability of the fieldis heterogeneous. It is that upper oil-bearing intervals are water-wet and lowers are oil-wet. In ad-dition.it discusses that the upper water-wet cores in LH11-1-4 well believed to be oil-wet by mistaken,because of the core pollution by oil-base drilling fluid. |
