| 摘 要： | 坪北油田属于典型的特低渗透油田,地层中的孔隙吼道基本以小孔隙吼道为主,注水开发常会出现油井附近地层的堵塞,降低地层的渗透率,阻碍油井正常生产。经过对导致油井附近地层堵塞的因素综合分析,坪北油田最终选择化学解堵剂与酸复配的复合解堵工艺。现场应用显示,本解堵技术效果明显,经济效益显著,有推广应用的前景。

| Abstract: | Pingbei oilfield belongs to ultra-low permeability oilfield,and the feature of the oil reservoirs is small pore and throat,the stratum was blocked during the course of water injection,reduced the permeability of the stratum,and blocked the normal production of the wells.Analyzing the factors for stratum plugging,the authors choose the composite blocking removal technology.The result of field application indicated that this blocking removal technology had notable good effect,remarkable economic benefits and a bright future for application. |
