吐哈盆地油气分布特征及勘探方向

OIL/GAS DISTRIBUTION CHARACTERISTICS AND EXPLORATION STRATEGY IN TURPANHAMI BASIN.

吐哈盆地继台北凹陷侏罗系勘探取得重大突破，发现大量煤成烃油气田后，又在台南凹陷三叠系发现了稠油油田，表现出多层系、多类型复合含油的特点。在盆地形成演化分析基础上，通过对三大含油气系统和四大聚油单元的油气地质条件、聚集规律的探讨和资源潜力的评价，提出了着眼侏罗—白垩系、二叠—三叠系及石炭系三大含油系统，立足台南、台北、托克逊、哈密四大聚油单元，遵循科学勘探程序，实现油气储量持续增长的勘探目标。

After major breakthroughs in exploration in Jurassic of Tabei sag in TurpanHami basin, and discovery of a lot of coalformed hydrocarbon oil/gas fields, heavy oilfields with multiple series and types combined hydrocarbonbearing were found in Triassic of Tainan sag. Based on analyses of formation and evolution of TurpanHami basin, this paper discussed oil/gas geologic condition and accumulating regularity of three major petroliferous systems (J-K, P-T ,C) and four major hydrocarbon accumulating units (Tainan, Taibei, Tuokexun and Hami), and evaluated resource potential, presented exploration strategy of following scientific exploration program and realizing continuous increase of oil and gas reserves.
