珠江口盆地特高含水老油田稳油控水配套技术研究——以LFZ13-1油田为例

The Auxiliary Techniques for Stabilizing Oil Production by Water Control in Mature Offshore Oilfield of Pearl River Mouth Basin——By Taking LFZ13-1 Oilfield for Example

稳油控水是海上油田进入开发中后期控制油气生产成本、延长油田经济寿命和提高最终采收率的重要途径。作为珠江口盆地特高含水老油田的典型代表——LFZ13-1油田在多年的增产挖潜实践中,努力推广新技术的开发及运用,探索提高地层产能新方法,同时将超深穿透射孔技术、高能气体造缝技术与"纵向产层置换"的整体方案调整进行有机地结合,取得了很好的增产稳产效果,并为海上油田节能减排闯出了一条新路。

For mature offshore oilfields,stabilizing oil production by water control was an important way of controlling the operation cost,extending the economic lifetime of oilfields and enhancing oil recovery.As a typical extra-high water cut mature oilfield in Pearl River Mouth Basin,LFZ13-1 Oilfield has made great efforts to promote the exploitation and application of new stimulation technologies in improving oil productivity for many years,and the deep penetrating perforation technology (Power-Ω),micro-crack perforation creating technology (Stim-Gun) were integrated with overall development plan adjustment 'of alternating vertical pay zones'.Great effect is obtained in oil increment and stabilizing production and saving energy and reducing emissions.
