蒸汽重力驱工艺的发展--以阿沙尔琴油田重质油藏为例

Development of Steam-Assisted Gravity Drainage Technology——An example from Ashalchinskoye heavy oil reservoir

鞑靼石油地质工作者在阿沙尔琴油田采用了蒸汽重力驱热采开采工艺,经反复试采,他们提出了适于该油田的双井口注蒸汽热采工艺,使稠油产量大幅度提高。在阿沙尔琴油田采用水平井蒸汽重力驱热采工艺所获得的成功经验,可以推广到所有地层厚度大于15 m的稠油油田。

In 2006 Tatnefi OAO has begun the unique project on extraction of high-gravity oil at Ashalchinskoye deposit with use of steam assisted gravity drainage （SAGD） technology. From six tested modes of pair wells operation the optimal one is determined. It is drawn a conclusion about the possibility of distribution of the received positive experience on all deposit on high-viscosity oils with a layer thickness more than 15 m.
