摘要
曙光油田以稠油开发为主,其中薄互层稠油油藏储量占稠油总储量的68.4%,目前可采储量采出程度达到85%以上,平均蒸汽吞吐12.5个周期。在现有的开发方式下,无法进一步改善油藏开发效果。为稳定产量规模,提高油藏最终采收率,2005年6月在典型的薄互层稠油油藏杜66块实施火驱采油技术现场试验。针对该块在试验开展以来出现的平面及纵向动用不均衡的问题,开展了平面及纵向动态调控技术研究,取得了较好现场实施效果。该技术可为薄互层稠油油藏火驱开发提供一定的借鉴。
The Shuguang oilfield is primarily under development of heavy oil,with reserves in the thin intercalated heavy oil reservoirs accounting for 68.4%of the total figure.Currently,the recovery extent of recoverable reserves is as high as over 85%,under huff and puff development at 12.5 cycles on average,Under existing development,it is very difficult to further improve the development result in the reservoirs,In order to stabilise the productivity and enhance the ultimate recovery factor,a Reld pilot of in-situ combustin recovery was conducted in Block Du 66- the typical thin intercalated heavy oil reservoir in June 2005,Focusing on the uneven producing arealy and vertically during pilot test,a study on adjustment and control technology of areal and vertical performance is made and good results are obtained.This technology provides certain referent for in- situ combustin recovery of thin intercalated heavy oil reservoirs.
