Controlling Factors of Reservoir Formation in Ramptype Lithostratigraphic Reservoir in Hinterland of Junggar Basin
-
摘要: 通过对准噶尔盆地腹部已知的缓坡型岩性油气藏的解剖和成藏控制分析,初步建立了这类岩性油气藏的成藏模式,根据其成藏要素构成将其称之为缓坡远源相控—断控型成藏模式。其成藏主要受构造背景、沉积体系的时空分布和构成、砂体的成因类型及叠置样式、是否存在油源断裂等方面因素的控制,并提出了盆地腹部油气藏勘探部署的指导思想。Abstract: Based on the anatomizing and analysis of controlling factors of the ramptype lithologic reservoir in the hinterland of Junggar basin, reservoir formation model is established preliminarily. According to the composing factors of reservoir formation, the model is named as faciesfault control type of ramp farsource model. This reservoir formation model is controlled by structural background, composition and distribution of sedimentary system, superimposition and cause of formation of sand body, oil source fault, and so on. In addition, the author gave the suggestions for oil and gas exploration in the hinterland of Junggar basin.
