This paper attempts to give an evaluation and study of hydrocarbon preserving units , which focuses on tectonic evolutions and time - space evolutions of hydrocarbon preserving conditions , on the basis of systematically collecting and using data from the well li - 1 and the neighboring area 基于此,本文在系統(tǒng)收集和利用利1井及鄰區(qū)資料的基礎(chǔ)上,以構(gòu)造演化為主線,以油氣保存條件的時(shí)空演化為重點(diǎn),開(kāi)展了油氣保存單元的評(píng)價(jià)和研究。
