| 摘 要： | 根据岩芯、电测曲线、录井、分析化验、地震等资料,分析了呼和湖凹陷下白垩统南屯组沉积相类型、沉积特征以及分布规律。研究表明,南屯组发育扇三角洲、辫状河三角洲、湖底扇和湖泊4种沉积相。扇三角洲主要分布在南一段的西北缓坡带和东南陡坡带,辫状河三角洲主要分布在南二段以及南一段的北部斜坡带,而在深湖-半深湖相中发育湖底扇。指出呼和湖凹陷南部沉积砂体为较有利的勘探区域,其中扇三角洲和辫状河三角洲前缘亚相带是油气聚集的重要相带。

| Abstract: | Sedimentary facies types,sedimentary characteristics and distribution law of Nantun group of Cretacic in Huhehu depression are analyzed on the base of core, well log curve, analysis assay, seismic and so on. The research indicated that Nantun Group developed fan delta, braided river delta, sublacustrine fan. This paper expounds in detail sedimentary characteristics and identification mark of fan delta, braided river delta and sublacustrine fan in cause, source supply, development position, sedimentary characteristics and seismic reflection characteristic. Fan delta mainly distributed in northwest gentle slope zone and southeast steep slope zone of Nanyi section; braided river delta mainly distributed in Naner section and north slope zone of Nanyi section; sublacustrine fan developed in deep lake-half deep lake facies . This paper pointed out that south sedimentary sand of Huhehu depression was the favorable exploration region at last, in which fan delta and braided river delta front subphase zone was the important hydrocarbon accumulation. |
