摘要
基于中海油深圳分公司流花11-1油田老化油配制的W/O型乳化液,采用静态静电聚结破乳实验,并辅助以离心机强化脱水,针对高频/高压脉冲交流电场下电场强度、频率、电压波形、含水率等因素对老化油乳化液电场破乳脱水效果的影响进行研究。结果表明:老化油乳化液的反相点位于40%～50%之间,W/O型老化油乳化液破乳脱水的最优电场参数为电压6kV、频率2kHz,波形为矩形波;以含水率40%较稳定老化油乳化液为例,其脱水率可达74.074%;改变乳化液含水率,最优电场破乳参数不变。上述研究结果可为流花油田老化油处理流程的改造提供设计参考,并可为生产运行参数的改进提供依据。
In this paper,based on the prepared aging oil W O emulsion from Liuhua 11-1 oilfield,the influence of electric field intensity,frequency,waveform and moisture content on electric demulsification and dehydration under high frequency and high voltage electric field was investigated.A static electrostatic coalescing device with a centrifuge assisted to enhance the dehydration rate.The experiment results indicated that the phase inversion point of aging oil emulsion is between 40%and 50%,the optimal electric field parameter for W O emulsion demulsification and dehydration is field strength(voltage)of 6 kV,frequency of 2 kHz and AC square wave.The dehydration efficiency of stable W O emulsion is 74.074%when the moisture content reaches 40%.These optimal electric field parameters do not vary with moisture content.This study can provide design references for the modification of aging oil treatment process in Liuhua oil field and a foundation for the improvement of production.
