摘要
西峡沟区块稠油油藏埋深浅,采用浅钻大位移井作为开发方式,可以有效增加油层裸露面积,扩大蒸汽热驱范围,大幅度提高单井采收率及综合经济效益。该文论述了浅钻大位移井的钻井难点,结合钻井难点形成了相应配套的工艺技术,并在马211、马212井得到成功应用,为西峡沟稠油油藏开发探索了一条有效途径。
The buried depth of heavy oil reservoir in block Xixiagou is shallow, taking extended - reach well as a development means increases bare area of oil layer, enlarges thermal drive extent of steam, and increases production rates of single well and comprehensive economic benefit. The difficulty of drilling extended - reach wells is discussed, combining the difficulties form relevant matching technology. The successful application of the technology in well Ma211 and well Ma212 provides an effective approach for development and exploration of heavy oil reservoir in Xixiagou.
