稠油油藏地层测试保温管技术

Insulation pipe technique for formation test of viscous oil reservoir

为了改善渤海稠油油藏地层测试效果,提出了保温管技术。介绍了保温管、测试管串的结构以及使用方法。现场试验及应用实践表明,应用保温管技术可有效减少原油流动过程中的热量损失,提高稠油油藏地层测试的成功率。

The insulation pipe technique has been developed for improving formation test effect of viscous oil reservoirs in Bohai Sea. The insulation pipe-drilling stem string and its using method are introduced. The field test and application results show that the insulation pipe technique can reduce the heat loss of crude flow effectively and raise the success rate of formation test of viscous oil reservoirs.
