摘 要: | 春风油田排601区块属于浅薄层超稠油油藏,由于油稠、地层非均质以及钻井轨迹的影响,先期开发的北区已出现9个井组、23个井次的热干扰现象,严重影响了蒸汽吞吐的开发效果。为解决热干扰问题,采取了组合式蒸汽吞吐和氮气泡沫调剖等措施,有效抑制和利用了汽窜,提高了蒸汽热能利用率,改善了油层动用状况,油井的周期产油量和油汽比均得到了提高。

Abstract: | Pal 601 block of Chunfeng Oilfield is a shallow, thin layer and ultra -heavy oil reservoir. As a result of high oil viscosity,formation heterogeneity and drilling trajectory, thermal interference has been emerged in 23 wells of 9 well groups of its north part in the early stage of development, which caused a serious impact on steam stimulation. So the combination of cyclic steam stimulation and nitrogen foam profile control were carried out, which has inhibited and utilized steam channeling effectively,improved heat efficiency, reservoir production and enhanced cyclic oil production and oil - steam ratio. |

Keywords: | shallow ultra - heavy oil steam channeling well combination of cyclic steam stimulation nitrogen loam profile control |
