摘要
对水膨体调剖剂进行了测定和评价。结果表明 ,在 75～ 90℃条件下 ,预交联水膨体调剖剂的岩芯突破压力梯度大于 2MPa/m ,堵水率大于 99.9% ,10PV水冲刷后堵水率大于 95 %。现场试验表明 ,调剖后增油效果明显。
The precrosslinking swellable particulate profile modification agents were evaluated and applied. The results showed that under condition of 75～90 ℃,the plugging rate of the agents were more than 99%,the core breakthrough pressure grade was more than 2.0 MPa,and the plugging rate was more than 95% after injected 10 PV water. The results of field trial showed that the oil yield could be significantly increased.
