中国石油网消息：4月15日，记者从华北油田获悉，该油田采油三厂在留107断块应用“行列注水”开发模式，通过注采井网优化调整，日产油从9.8吨稳步跃升至25.8吨。

China Oil News: On April 15th, a reporter from Huabei Oilfield learned that the Third Oil Production Plant of this oilfield has adopted the "row-by-row injection" development model in the 107 fault block. Through the optimization adjustment of the injection and production well network, the daily oil output has steadily increased from 9.8 tons to 25.8 tons.

面对剩余油难以有效动用的发展瓶颈，华北油田技术团队主动转变开发思路，创新推出“行列注水”开发模式，将传统面积注水井网优化调整为注水井排与采油井排平行或交错布置的行列式井网，通过科学改变地下液流方向、强制流体转向绕流，进一步扩大水驱波及范围，提高注水利用率，实现平面剩余油的精准挖潜，为老油田挖潜增效开辟了全新路径。

Facing the development bottleneck where the remaining oil is difficult to be effectively exploited, the technical team of North China Oilfield actively changed their development思路 and innovatively launched the "row-column injection" development mode. They optimized and adjusted the traditional area injection well pattern into a row-column type well pattern where the injection wells and production wells are arranged parallel or intersecting. By scientifically changing the direction of underground fluid flow and forcing the fluids to turn and flow around， they further expanded the water drive coverage area， improved the injection utilization rate， and achieved precise exploitation of the remaining oil in the plane， opening up a new path for the exploitation and efficiency improvement of old oilfields.

在推进过程中，技术团队坚守“地质认识先行、流场精准调控”的融合思路，研发复杂断块渗流场分级表征技术，创新构建“断、变、增、匀、强、建”六大注采调控模式。

During the implementation process, the technical team adhered to the integrated concept of "geological understanding taking precedence and precise control of flow fields", developed the hierarchical characterization technology for complex fault-block seepage fields, and innovatively constructed six major injection-production control models: "faulting, variation, increase, homogenization, strengthening, and establishment".

在留107断块，针对主力砂体注水突进、剩余油动用不足等问题，该团队将原有的反七点井网调整为行列式注水井网，有效引导平面液流转向，充分激活区块剩余油潜力。

In the 107 block, in response to the problems such as water injection breakthrough in the main sand bodies and insufficient utilization of remaining oil, the team adjusted the original reverse seven-point well pattern to a row-and-column type water injection well pattern, effectively guiding the flow of liquid in the plane and fully activating the remaining oil potential of the block.
