2026 年 3 月 7 日 行业研究 美伊冲突持续背景下，如何看待石化化工板块投资机会？ ——石油化工行业周报第 441 期（20260302—20260308） 要点 美伊冲突持续背景下，如何看待石化化工板块投资机会？美伊冲突持续一方 面会直接推高全球油价，另一方面伊朗若长期封锁霍尔木兹海峡，将推高原油 及化工品运输成本，伊朗局势如何演绎将很大程度影响全球化工品走势，全球 能源及化工品供需格局或将迎来重塑。在此背景下，我们认为建议关注三大主 线：1）继续看好油气板块，看好上游、油服、油运等板块的长期价值；2） 关注地缘冲突背景下的化工品供需格局重塑；3）关注油头的替代路线——煤 化工板块。 原油价格大幅上涨，油气、油服、油运长期价值凸显。原油供需面临一定压 力，但本轮地缘政治冲突有望使原油供需担忧得到缓解，地缘风险溢价的整体 上升有望在一段时间内持续推高油价。作为上游油气领域央企巨头，"三桶油" 和油服在油价上行期的业绩弹性凸显。2026 年，"三桶油"将继续维持高资 本开支，不断加强天然气市场开拓，加快中下游炼化业务转型，有望实现穿越 油价周期的长期成长。油服方面，国内高额上游资本开支投入将有力保障上游 ...
