高3618块稠油油藏于2008年转入火驱开发以来受油层高温氧化燃烧、区块蒸汽吞吐高轮次、地下存水多、油层大面积脱气等因素影响油井乳化现象日趋严重,油井产能下降,在对该火驱区块乳化油井进行综合分析的基础上,积极探索乳化油井现场破乳方法并实践,取得了较好的效果,对火驱区块乳化油井的进一步管理具有指导性意义。
Since 3618 heavy oil reservoirs were transferred to the fire flooding development in 2008, the oil well was emulsified under the conditions of high temperature oxidation and combustion, block high-throughput steam huff and puff, excessive underground water storage and large-area degassing of oil layers. The well On the basis of the comprehensive analysis of emulsified oil well in the fire flooding block, the method of field emulsion breaking in the emulsified oil well is actively explored and practiced, and good results are achieved, which is instructive for the further management of emulsified oil well in the fire flooding block significance.
