摘要
草20块是一个具有边水的构造岩性特稠油油藏,针对西部未动用区油层薄6~8m,受边水及东部高含水带影响大的特点,采用了水平井代替直井进行热采开发,并对水平井热采参数进行了优化设计。现场实施后,单井日产油峰值达到40t,平均单井年产油量在5000t以上,取得了较好的开发效果,为同类油藏的开发提供了指导和借鉴。
Cao 20 block is a structural - lithologic super - heavy oil reservoir with edge water. In viewing of that the non-producing oil layers in the western part are 6 - 8m thick and are significantly influenced by edge water and the high water cut zone in the eastern part, horizontal wells are used to perform thermal recovery and production parameters of the horizontal wells are optimized. Single well daily output peaks at 40t and average annual production of single well is over 5000t.
