摘要
松辽盆地南部深层火山岩气井长深5井储层埋藏深达5200m,温度高达183℃,针对该储层特点,室内进行了超高温低伤害压裂液的配方试验,合成了高温交联剂和高温增效剂,并进行了新型羧甲基胍胶超高温压裂液体系的性能评价。室内实验结果表明,羧甲基胍胶压裂液具有耐高温(180℃)、低浓度、低残渣、低伤害、低摩阻的特点。该压裂液体系在长深5井现场应用,压裂施工取得成功,压后获得了很好的增产效果。
The burial depth the reservoir of Changshen 5 well is 5,200m and the temperature reaches as high as 183℃. In view of the characteristics of the reservoir, lab test is launched on the formulations of ultra-high temperature and low-damage fracturing fluid, high-temperature crosslinker and synergist are synthesized. Meanwhile, performance evaluation is conducted on the new carboxy methyl-guanidine (CMG) ultra-high temperature fracturing fluid system. Lab test results show that the CMG fracturing fluid features in high temperature (180℃), low concentration, low residue, low damage, and low friction. The fracturing fluid system has been applied to Changshen 5 well successfully, and the production was enhanced a lot.
