近日，位于我国北部湾海域的涠洲10-5油气田获得高产油气流，标志着北部湾盆地古生界潜山油气勘探获重大突破，为我国海洋石油工业发展开辟了新战场，对保障国家能源安全具有重要意义。
▲钻井平台在北部湾海域开展钻探作业
涠洲10-5油气田位于南海北部湾海域，距离北海市约75公里，平均水深约37米。探井钻遇油气层283米，完钻井深约4840米。经测试，该井日产天然气约37万立方米，日产原油约102吨，成为北部湾盆地首个花岗岩潜山油气勘探发现。

花岗岩潜山是北部湾盆地油气勘探的“硬骨头”，面临着成山过程及成储机制复杂、花岗岩分布范围不明、有利储层预测难度大等三项难题，油气成藏庞杂。为此，勘探研究团队通过老井地层岩性复查、古生物鉴定、构造解析和地震反演等技术方法，确定花岗岩形成时代，明确花岗岩分布规律。同时，结合地球物理预测技术，研究储层发育机制与主控因素，成功预测花岗岩有利储层分布区。在钻探阶段，研发创新钻井技术与测试工艺方法实现储层保护，求取花岗岩储层准确产能，推动涠洲10-5油气田取得勘探突破。
此次在北部湾盆地探获勘探发现，将有助于保障油气资源的稳定供应，为经济社会发展持续贡献海油力量。
