介绍埕北油田的油藏特征,并结合埕北油田开发的实践,分析造成油层伤害的因素。根据油井堵塞机制选择了适用于海上油田的化学解堵剂和解堵施工工艺。室内实验和现场试验结果表明U-01解堵剂解堵效果显著。
This paper introduces the reservoir characteristics of Tiebei Oilfield and analyzes the factors that cause oil layer damage in combination with the practice developed in Tiebei Oilfield. According to the oil well plugging mechanism, the chemical plugging agent and the plugging plugging construction technology suitable for the offshore oilfield are selected. Laboratory experiments and field test results show that the U-01 blocker plugging effect is significant.
