克拉玛依稠油区块属砂岩油藏,由于长期的蒸汽吞吐造成地层出砂严重,在多年的生产中由于出砂造成九区大量油井减、停产,产生大量修井费用,对整个油田的开采效果造成严重影响,针对九区稠油区块严重出砂的躺井,对不钻塞人工井壁防砂工艺技术进行优化。现场施工达到了恢复了躺井的产能,提高了生产时率的目的取得了良好的效果。
The Karamay heavy oil block is a sandstone reservoir. Due to severe sand production caused by long-term steam stimulation, a large number of oil wells in nine districts have been reduced or stopped production due to sand production in many years. As a result, a large amount of workover costs have been incurred, affecting the entire oilfield Causing serious impact. In view of the serious sand production in the heavy oil block of the nine districts, the artificial sand wall technology for sand control without drilling was optimized. The on-site construction has achieved the effect of recovering the capacity of laying the well and increasing the production rate.
