准噶尔盆地吉木萨尔凹陷岩性地层油气藏研究
|
摘要
准噶尔盆地吉木萨尔凹陷东斜坡是新疆油田深化岩性地层油气藏勘探和实现油气增储上产的重要战略领域之一,具有良好的勘探前景。综合运用钻井、测井、分析化验以及地震资料,对该地区二叠系梧桐沟组沉积、储层和成藏进行了综合研究。梧桐沟组沉积相类型为辫状河三角洲和湖泊相,其中辫状河三角洲前缘水下分流河道砂体和平原的辫状河道砂体为最有利的储集砂体;通过储层综合评价,将储层分为4类,梧桐沟组储层主要为III类较好储层。梧桐沟组岩性地层圈闭具有油源近、物性好、盖层厚、较可靠的特征。深化本区岩性地层油气藏勘探关键是做好层序地层学指导下的储集体预测技术的综合应用,从而对辫状河三角洲前缘水下分流河道超覆型砂体和平原辫状河道砂体进行更有效的预测和识别。
The eastern slope of Jimusar Sag of Junggar Basin which shows good exploration prospect is a very important strategic area that can make Xinjiang oilfield enforce litho stratigraphic hydrocarbon reservoir exploration and increase oil-gas reserve and production.The sedimentary facies,reservoir and injection of the Wutonggou Formation are studied by using drilling,logging,testing and seismic data.The major facies are braided river delta which subaqueous distributary channels of the front and braided channels of the plain are the most favourable high-quality reservoir sand bodies and lacustrine.The reservoir can be divided into four types,and litho stratigraphic trapsWutougou Formation are mainly type III,which are neat the source of good physical property and thick cap look,and are of better reliability.The key to better litho stratigraphic hydrocarbon reservoir exploration is application of reservoir prediction technologies base on sequence stratigraphy,which can make the sand bodies prediction and identification of subaqueous distributary channels onlap of the front and braided channels of the plain more available.
