过筛管压裂增产防砂技术在海上油田的应用

Application of Screen Fracturing Technology to Increase Production and Sand Control in Offshore Oil Fields

渤海油田进入"双高"阶段后,老油田稳产增产难度逐渐加大,常规措施增油量有限,工程技术人员通过应用过筛管压裂工艺技术取得了良好的应用效果,同时也总结出了适用于渤海油田高渗透储层增产措施的施工思路。文中对不同射孔方式后作业效果及拖轮压裂作业模式的适用性进行了探讨,对多井次的实践应用及关键工具进行了分析,并提出了建设性的改良措施或建议。现场作业实践表明该技术具有较大应用潜力,是稳产增产的有效技术手段,为后续该技术将在渤海油田进一步扩大应用,在增产挖潜产能方面提供了新的作业思路。

After Bohai oilfield entered the "double high" stage, it is increasingly difficult for the old oilfield to stabilize production and increase production, and the conventional measures to increase oil are limited. Through the application of screen fracturing technology, good application results have been achieved, and at the same time, the construction ideas suitable for the high permeability reservoir stimulation measures in Bohai oilfield were summed up. The effects of different perforation modes and the applicability of tug fracturing mode were discussed, the practical application of multiple wells and key tools were analyzed, and constructive improvement measures or suggestions were put forward. Field practice shows that this technology has great application potential and is an effective technical means to stabilize production and increase production, which provides a new operation idea for further expanding the application of this technology in Bohai oilfield to increase production and tap potential production capacity.
