摘　　要：低渗-特低透油田随着长期的注水开发,初期压裂投产开发所形成的复杂人工裂缝成为井组内油井含水升高的主要原因。目前,解决注入水沿裂缝窜流、油井水淹的主要技术为调剖堵水,通过改善注水井吸水剖面,使其能够均匀分布,来达到稳油控水的目的。In the low-permeability-extra low-permeability oilfield,with the long-term water injection development,the complex artificial cracks formed by the initial fracturing and production development have become the main reason for the increase of water content in the wells in the well group.At present,the main technology for solving the turbulent flow of the injected water along the crack and the flooding of the oil well is the profile control and water shutoff.By improving the water absorption profile of the injection well,it can be evenly distributed to achieve the purpose of stable oil control.
