摘要 春光油田春10井区特稠油油藏是一个典型的边际稠油油藏,具有油层埋藏深、厚度薄、原油黏度高、含油层位少的特点,采用常规的开发动用技术难以实现油藏的经济有效开发。自2011年以来,通过开展水平井开发经济技术政策界限研究,确定了以水平井为主导、采用蒸汽吞吐+蒸汽驱的开发方式整体动用该区568×104t稠油储量的开发思路,成功在该区部署实施99口水平井,预计新建产能16.6×104 t,取得了良好的开发效果。 Chun-10 well block of Chunguang oilfield is a typical marginal heavy oil reservoir and has the characteristics of deep buried depth,thin thickness,high viscosity of crude oil and less oil bearing layers,by adopting the conventional developed producing technology,it is difficult to realize economic and effective reservoir development.Since 2011,through policy limit study on economic and technological development of horizontal wells,the horizontal wells have been determined.Steam stimulation + steam drive development way has been adopted to produce 568 x104 t reserves and 99 horizontal wells have been successfully deployed in the block.The new expected capacity is about to be 16.6 x104 t and good development effect has been achieved.
