试论埕岛和桩西之间低潜山的勘探

DISCUSSION ON THE EXPLORATION OF LOW BURIED-HILLS BETWEEN CHENGDAO AND ZHUANGXI AREAS

桩西和埕岛古生界潜山都已取得了很大的勘探成果 ,该文从构造演化的角度分析了桩西潜山和埕岛潜山的形成 ,说明桩西潜山和埕岛潜山地质历史时期曾经属于同一构造带。从油气成藏的角度 ,通过类比分析 ,指出两潜山之间的低部位潜山无论从生烃、排烃还是油气的运移和聚集等方面都具有良好的油气成藏条件 ,有形成低潜山油藏从而使桩西和埕岛潜山含油连片的可能。桩西和埕岛之间的结合部位仍具有很大的勘探潜力 。

The exploration of the Paleozoic buried hills in Zhuangxi and Chengdao areas has achieved great results. In terms of tectonic evolution, the buried hills in Zhuangxi and Chengdao once belonged to the same structural zone in geological history. Based on analogy analysis, the low parts between two buried hills show favorable conditions for hydrocarbon accumulation, which might results in the formation of a united play in the buried hills. Therefore, the connective parts between Zhuangxi and Chengdao may be a potential area for hydrocarbon explorotion.
