塔里木轮南油田三叠系层序与岩性圈闭
|
摘要
塔里木板块轮南井区三叠系为典型的克拉通内凹陷盆地型陆相碎屑岩,主要由湖泊和三角洲沉积体系构成产油层系。层序单元的划分对比是岩性油气藏圈定的核心技术,以测井和三维地震资料为依据建立井震合一的层序地层格架,所划分的3个层序8个体系域控制了三套区域性和多套局部性储盖组合。区域性储盖组合以层序为单元,层序下部的低位体系域和湖侵体系域砂岩组成区域性储层,上部高位体系域的湖相和三角洲相泥岩为区域性盖层,以构造圈闭为主;局部性储盖组合以体系域为单元,由同一体系域的砂岩和邻近泥岩组成,以岩性圈闭为主。结合地震储层预测技术可划定新的岩性地层圈闭,高位体系域期和湖侵体系域中发育的局部性储盖组合是岩性地层圈闭勘探的重点。
The Triassic sequences in Lunnan Oil Field , Tarim Block are typically of the continental basin within depression belt of craton.Lacustrine and delta sedimentary systems are significant of the oil-gas reservoirs.Division and correlation of the sequence stratigraphic units are key aspects for the outline of the lithological trap.The present study works out the sequence stratigraphic framework based on seismic and well-measurement data.Three regional as well as multiple local reservoir-cap associations are controlled by three sequences and eight system tracts respectively.Sequence , in which lowstand system tracts and transgressional system tracts from its lower part of the sequences compose of the the regional reservoir-cap associations ; meanwhile , highstand system tracts formed by lacustrine and delta mudstones from the upper part are notable regional cap layer.Tectonic factor is considerable for the trap.System tracts composed of sandstone as well as surrounding mudstone are generally of the local reservoir-cap trap and catalogued to the lithological-type traps.Synthetic seismic forecast reservoir data is favorable for the outline of the lithological trap.We will pay more attention to the local reservoir-cap units of the transgressional system tracts formed during highstand episodes.
