摘要

摘要: 通过对准噶尔盆地滴南凸起石炭系火山岩岩心、铸体薄片的详细观察以及样品的压汞曲线和孔渗分析认为:研究区火山岩储集体岩石类型复杂;不同岩性的火山岩其储集空间发育特征不同,表现为受岩性、成岩作用以及构造发育的影响,其储集空间类型具有多样性。研究区整体呈现出孔隙发育受风化壳和裂缝的控制作用。成像测井分析认为火山岩体中裂缝较发育,且通过对裂缝的识别与分析得出研究区裂缝发育北东向,整体受近东西向的区域大断裂控制明显。同时对石炭系气藏的剖析认为断层对火山岩气藏具有改善和破坏作用,表现为断层对储层储集性能的改善作用和油气运移的优势通道作用,以及断层对研究区气藏盖层的破坏作用。

Abstract: By complicated analysis of volcanic core,casting thin sections,intrusive mercury curve of samples and porosity-permeability of gas reservoir in Dinan Uplift of the Junggar Basin,it suggests that the igneous rock reservoir has complex types.There are different reservoir spaces in various lithological igneous rocks,which mainly manifested as that the types of reservoir spaces are various and dominated by lithology,diagenesis and structural development.In a whole,the porous development is controlled by weathering crust and fracture.By an analysis of imaging logging,the more fractures are developed in the igneous rocks.By recognition of fractures,it is obtained that the orientation of these fractures are mainly north-east trending and are obviously controlled by near east-west trending regional major fracture.By an analysis of Carboniferous gas reservoir,it is considered that the faulting has improvement and destroying effect on igneous gas reservoir.That is to say,faults not only can improve reservoir property and provide dominant pathway for gas migration,also can destruct action on the cap rocks of gas reservoir.
