| 摘 要： | 以寻找塔里木盆地碳酸盐岩油气勘探接替领域为目的,在和田河气田周缘采用古构造演化的方法,结合和田河气田单井油气水分析,建立了玛南奥陶系潜山准层状成藏模式和玛北台缘带古油藏成藏模式;指出和田河气田周缘存在玛南奥陶系潜山、玛北奥陶系台缘带和玛东奥陶系推覆构造带三大油气勘探领域,区带资源量约1万亿m3,是塔里木盆地碳酸盐岩勘探的重要接替领域。玛南奥陶系潜山暴露时间长,风化、淋滤作用强,形成良好的岩溶型储层,上覆石炭系泥岩和上倾位置的致密灰岩作为盖层,形成良好的储盖组合,同时处于有效生烃范围之内,是有利勘探领域。玛北发育奥陶系台缘带,而且与构造圈闭相叠置,可以捕获早期运移的油气,是较有利勘探领域。玛东奥陶系推覆带潜山披覆圈闭发育,规模较大,是潜在勘探领域。

| Abstract: | For the purpose of the finding of the relayed carbonate exploration field in Tarim basin,based on the research of structural evolution of peripheral area and the well analysis of the Hetianhe gas field,this paper sets up the Ordovician burial hill quasi-layered pool model in southern Mazhatage and fossil oil pool model of platform margin belt in northern Mazhatage.This paper points out three main Ordovician exploration areas: burial hill in southern Mazhatage,the platform margin belt in northern Mazhatage and the nappe structures in eastern Mazhatage,which is the relayed exploration area with one trillion stere nature gas.The burial hill in southern Mazhatage formed good carbonate reservoir for the actions of weathering and leaching in the long term exposure,and its overlaying Carboniferous shale and its updip compact limestone formed the good cap,and it also lays in the area of effective source rock,so it is a favorable exploration area.The platform margin belt in northern Mazhatage which superimposed the structure trap can trap the oil and gas,so it is a more favorable exploration area.Large-size drape traps developed in nappe structures in eastern Mazhatage are potential exploration areas. |
