    巴基斯坦海域油气勘探方向探讨

    PRELIMINARY STUDY ON THE OIL AND GAS EXPLORATIONTARGETS IN OFFSHORE PAKISTAN

    • 摘要: 为了寻找巴基斯坦海域油气勘探方向,对收集的大量文献资料进行了整理和分析,并对最新采集的柱状样进行了测试分析,发现巴基斯坦海域烃源岩普遍存在,而储集岩主要为始新统的生物礁和中新统的河道砂岩。巴基斯坦海域北部的马克兰增生楔物源可能主要为细碎屑岩,中新统的河道砂岩分布局限,油气勘探前景差;而在巴基斯坦海域东部的印度扇,中新统河道砂岩分布广,储集性能好。因此,巴基斯坦海域的油气勘探应以东部印度扇为勘探靶区,其主要的勘探层位应以陆架区中新统的河道砂岩和深水区始新统的礁灰岩为主。

       

      Abstract: In order to find out the future direction for oil and gas exploration in the offshore areas of Pakistan, a large amount of literatures was collected and analyzed, and the newly collected columnar samples were tested and analyzed. It was found that source rocks are available in offshore Pakistan and reservoirs are mainly composed of Miocene channel sandstones and Eocene reef limestone. In the northern part of Pakistan Seas, however, the sediments were mainly sourced from the fine-grained clastic rocks of the Makran accretionary wedge, and the Miocene channel-levee complex is limited, and thus the oil and gas exploration prospects are quite poor. However, in the Indus fans off eastern Pakistani, the channel-levee complex is widely distributed as high quality reservoirs. Therefore, it is suggested that the Indus fan in the eastern Pakistan Sea be selected as the target area for future oil and gas exploration taking the Miocene channel sandstone on the continental shelf and the Eocene reef limestone in the deep water as main exploration horizons.
