| 摘 要： | 水平井是高尚堡浅层油藏主要的开发方式。地层出砂造成的防砂管柱堵塞严重影响了油井产能,多次常规酸化解堵效果不理想,为此引进了声波振荡解堵技术。从颗粒解堵、提高地层渗流性、降低流体黏度等方面探讨了声波振荡解堵的技术原理。基于水平井防砂管柱及近井地带堵塞类型分析认为,生产过程中的地层出砂颗粒运移堵塞是水平井的主要堵塞类型。高尚堡浅层油藏7口水平井的应用效果表明,该技术施工简单、成本低、增油效果好,可在水平井解堵中推广应用。

| Abstract: | Horizontal wells are predominantly applied to produce the Gaoshangpu shallow reservoir.The productivity of the wells has been adversely affected by sand control pipe plugging caused by formation sand production.Plugging removal by conventional acidizing was not satisfactory,so that the technology of acoustic oscillation deplugging has been introduced.The technical principle of acoustic oscillation deplugging is discussed in terms of particle removal,improving formation permeability and reducing fluid viscos... |
