辽河稠油SAGD开发地面工艺关键技术
|
摘要
为寻求蒸汽吞吐后进一步提高采收率的有效接替方式,辽河油田于2005年开始在曙一区杜84块主体部位开展超稠油SAGD开发方式的研究、试验与推广工作。通过对国外SAGD技术考察,对已建地面工艺设施大量调研,并与科研单位联合进行技术攻关,结合辽河油藏物性,在杜84块相继开展SAGD先导试验、工业化试验以及工业化应用。经10年运行与改进,归纳形成了一系列具有辽河特色的油气集输、原油处理、稠油注汽、稠油污水处理、热能利用等地面工艺的关键技术。截至2017年底,杜84块累计建设72井组,年产油量105.7×10~4t,比吞吐阶段峰值产量高14.9×10~4t,SAGD阶段累积产油692.5×10~4t,建成了集油气集输、原油脱水、注汽、污水处理等生产设施为一体的SAGD工业区,为辽河油田稳产千万吨做出了重要贡献。
In order to find an effective alternative way to further enhance the oil recovery after steam huff and puff,Liaohe Oilfield has been conducting researches,tests and promotions about the SAGD development mode for conversion of super heavy oil in the main part of Block Du84 since 2005.Through the investigation of foreign SAGD technology,a large scale of investigation has been carried out about existing surface process facilities, and technological breakthrough has been made together with the scientific research units. Combined with the physical properties of the Liaohe Reservoir,pilot tests,industrialization tests and industrial applications have been carried out in Du 84 in succession. After ten years of operation and improvement,a series of key technologies for surface technologies such as oil and gas gathering and transportation, crude oil processing, heavy oil steam injection, heavy oil wastewater treatment and thermal energy utilization with Liaohe characteristics have been formed. By the end of 2017,72 well groups have been built in Block Du84 of Shu1 Area,with an annual oil production scale of 105.7×10~4 t. Compared with the peak oil production at huff and puff stage,the peak oil production is 14.9× 10~4 t higher,and the cumulative oil production at SAGD stage is 692.5×10~4 t.A SAGD industrial zone with oil and gas gathering and transportation,crude oil dehydration,steam injection and sewage treatment facilities have been built,making important contributions to the stable production of 10 million tons in Liaohe Oilfield.
