吐哈盆地红南9-12井新发现含油气地层归属探讨
|
摘要
吐哈盆地红连油田下白垩统三十里大墩组与上侏罗统喀拉扎组之间发现了一套新的含油气地层。通过对岩电、重矿物组合、粘土矿物等特征及地震层序分析,认为该套地层位于不整合面之上,应归属于下白垩统三十里大墩组下段较为合理。该套地层在研究区普遍具备成藏的基本条件,应作为进一步勘探的有利目标。
A new set of oil-gas bearing layer between Sanshilidadun formation of Lower Cretaceous and Kalazha formation of Upper Jurassic has been found in Honglian oil field in Tuha basin. This paper presents the correlation and demonstration of several opinions on the new oil-gas bearing layer classification based on the integration of multi-disciplinary information such as core,logging and seismic features. It is concluded that the new oil-gas bearing layer is located above the unconformity between the Cretaceous and the Jurassic, and should be classified into Sanshilidadun formation of Lower Cretaceous. The new oil-gas layer could be as a favorable target for further exploration for it is of basic conditions of hydrocarbon accumulation in this area.
