摘　　要：渤海C油田主要开发方式以水平井井型生产,采用裸眼或砾石充填完井,优质筛管防砂。由于前期的投资限制,部分油田区块采用简易平台开发。受限于平台空间无修井机,部分井在生产后无法达到产量预期,需通过大型作业来改变油井产能。2020年,在C油田W平台实施了渤海首口水平井过筛管压裂改造措施井,截至2023年9月5日该井累计增油1.7万m3,证明该项措施可以产生较好的经济效益。The main development method of Bohai C oilfield was horizontal well type production,using open hole or gravel filling completion,high-quality screen tube sand control.Due to investment limitations in the early stage,some oilfield blocks were developed using simple platforms;Due to the limited platform space without a repair rig,if some wells cannot meet the expected production capacity after production,large-scale operations were required to change the oil well production capacity.In 2020,the first horizontal well in Bohai Sea was subjected to screen tube fracturing transformation measures on the W platform of C oilfield.As of September 5,2023,the well has accumulated an increase of 17000 cubic meters in oil production.Practice has showed that this measure has good economic value and also has good economic effects on offshore oil fields.
