麦盖提斜坡西段奥陶系岩溶储层分布特征及勘探意义
|
摘要
麦盖提斜坡在石炭系和泥盆系已发现油气藏和油气显示。近期发现奥陶系潜山成藏条件优越,是一套潜在的含油气层系,勘探意义较大。奥陶系具备形成规模性油气藏的油气源条件;二维、三维地震的精细标定、联合解释及预测分析表明奥陶系鹰山组潜山岩溶储层发育;奥陶系鹰山组古岩溶潜山与上覆柯坪塔格组下段泥岩构成良好的储盖组合;在麦盖提斜坡由北倾向南倾构造格局发生调整的过程中一直处于油气运聚的有利部位,油气运聚匹配关系较好。
Oil & gas reservoir has been discovered in Carboniferous and Devonian Systems in Maigaiti slope.Recently,it is found that Ordovician buried hill has favorable conditions for reservoir formation.This is a set of potential oil & gas strata,and it has great significance for exploration.The Ordovician has oil & gas source conditions for forming large-scale oil and gas reservoir.Two-dimensional and three-dimensional fine calibration,integration interpretation,and predictive analysis show that karst reservoir developed in Yingshan Formation buried hill of Ordovician,favorable reservoircap rock assemblages are formed by the karst buried hill of Ordovician Yingshan Formation and the shale in lower part of overlying Kepingtage Formation,Maigaiti slope has been in a favorable position of oil and gas migration and accumulation during the structural adjustment from north to south,oil and gas migration and accumulation match well.
