摘要
针对采油井大范围出砂, 砂埋油层, 砂堵井筒, 频繁冲砂检泵致使有效采油时间缩短,油层污染加速, 常规采油工艺和“三抽”设备不能满足采油井在复杂地质条件下的生产需要等问题, 研发了有杆泵携砂采油井筒配套技术。该技术以提高系统采油时效为目标, 在井筒内配置双柱塞抽油泵, 液力冲砂器和管柱沉砂器等机具, 通过与抽油机和抽油杆等杆管附件进行合理匹配,集冲搅砂和携砂为一体, 提高采油井有效生产时间, 达到增油和降低系统总体生产成本的目的。系统性能型式试验和工业生产试验说明, 该井筒配套技术通过在泵上实现存、携砂, 泵下冲搅砂等有效措施, 能使油井延长正常采油时间, 降低检泵作业次数, 减少油层污染并提高采油时效。
To meet the need of sand-carrying rod pumping, the technology for matching of the downhole tools and pump is developed. Double plunger pump and patented hydraulic sand washing device and string sand settling device are adopted. By matching with the pumping unit and sucker rod reasonably, these downhole equipment carry out sand-carrying oil production, and improve virtual production time and increase the production of crude oil. Type test and industrial test show that the technology can extend normal production time and improve oil production efficiency.
