超稠油水平井高温调剖技术

超稠油水平井的开发，为油田上产提供了一项新的开发工艺，但由于油藏层间、层内的非均质性，在注汽过程中，注入的高温蒸汽向高渗透层进入，导致吸汽剖面不均匀，降低了蒸汽利用率、体积波及系数及开采效果。为了解决这一矛盾，研制开发了一种适用于超稠油水平井的高温调剖技术。该技术采用凝胶与树脂颗粒相结合进行调剖，以封堵高渗透层，改善吸汽剖面，提高蒸汽吞吐效果。

High temperature profile control technology of super heavy oil horizontal well

The development of super heavy oil horizontal well provides a new development technology for enhancing the oilfield productivity. High temperature steam penetrates the high permeability reservoirs during steam injection because of interlayer and intraformational heterogeneity within the reservoirs,which leads to the uneven steam absorption profile,reduces the steam utilization and volumetric sweep efficiency and decreases the production effect. To resolve this problem,we developed the high temperature profi...
