哈东洼槽是二连盆地油气勘探获得突破的第一个次级小洼槽。本文通过成果,同时通过对哈东洼槽勘探历程的回顾,进一步揭示了加强区带地质综合研究,提高施工质量,提高认识和评价油层的技术手段,以及针对久攻不克的地区,地质研究要冲破束缚、解放思想、创新认识的重要性;同时也揭示了次级小洼槽只要有有利的烃源岩建造,就可以形成工业性油气富集,其中近油源并处于主油气运移方向上、叠置有利砂体的长期继承性构造高点圈闭,是勘探突破的首选目标。
Ha Dong depression is the second sub-depression that made breakthrough in oil and gas exploration in Erlian Basin. Based on the results and the review of the exploration process in the East and East Kazakhstan brakes, this paper further reveals the technical measures to strengthen the comprehensive study of the regional geological geology, improve the construction quality, raise awareness and evaluate the oil layers, and geology research It is necessary to break through the shackles, emancipate the mind and create awareness of the importance of understanding; but also reveals that secondary sub-depression as long as the favorable source rock construction, can form industrial oil and gas enrichment, near oil source and in the main oil and gas migration Direction, the superimposed sand body of the long-term succession of high structural traps, exploration breakthrough is the preferred target.
