分析了渤南油田注入水水质 ,探讨了其对油层的伤害。结果表明 ,渤南油田注入水结垢严重 ,注入水中固相颗粒对油层的伤害较大。据此选用阻垢剂 S2 -3保护油层 ,对其进行评价表明 ,阻垢率可达 90 %以上。 The injection water quality in Bonan oilfield was analyzed and the damage to the oil layer was discussed. The results show that the injected water in Bonan oilfield has serious scaling and the solid particles injected into the water are more harmful to the oil layer. According to the selection of scale inhibitor S2 -3 to protect the reservoir, its evaluation showed that the scale inhibition rate of up to 90%.
