多支链型与直链型聚醚破乳剂对桑塔木原油破乳的对比试验

Comparison Test For Multiple Branched Chain Type Polyethers Demulsifying Agent With Straight Chain Type to Sangtamu Crude

桑塔木油田的原油物性介于稀油和重油之间，具有其特殊的物性特点，本文以多支链型破乳剂（APE型为代表）和直链型破乳剂（BPE型为代表）从脱水率、脱水温度、脱水速度、加药浓度四个方面进行了破乳对比试验，从而对这类原油的破乳规律有了更深一层次的认识。

The physical-chemical properties of Sangtamu curde is among light and heavy oil,has its own special properties. This article makes comparison test on multiple branched chain demulsifying agents (APE type ) with straight chain (BPE 'type ), compares the following four aspects:dehydration rate,temperature, speed and adding chemicals density etc, therefore undersatands the demulsifying regular of this kind of crude more deeply.
