由于新滩油田地层中油水流度比大,区块内稠油油藏普遍具有低含水期短和含水上升快的特点。本文主要介绍了氮气泡沫调剖蒸汽吞吐技术的现场试验情况以及温敏凝胶堵水技术的先导试验情况。在对部分成功和不成功井例试验效果分析的基础上,初步总结了氮气泡沫调剖以及温敏凝胶堵水封堵工艺技术特点和选井规律,以指导下步该工艺的推广应用。
Due to the large ratio of oil to water in the formation of the Xintan oilfield, the heavy oil reservoirs in the block generally have the characteristics of low water cut and fast rising of water content. This article mainly introduces the field experiment of nitrogen foam profile control steam huff and puff technology and the pilot test of temperature-sensitive gel water-blocking technology. Based on the analysis of some successful and unsuccessful well test results, the characteristics of nitrogen foam profile control and temperature-sensitive gel water plugging and plugging technology and the well selection rule are summarized, which will guide the popularization and application of the next step.
