摘要
定边地区位于鄂尔多斯盆地陕北斜坡西北部,横跨天环向斜。侏罗系延安组作为主要的产油层之一,具有规模较小、分布相对分散的特征。延安组分为10个油层组,其中延10全区广泛沉积,但是储层分布变化大,非均质性较强。近年来,定边地区延10勘探有所突破。为了进一步扩大延10油藏的分布规模,预测潜在有利区,对储层特征进行系统研究至关重要。
     论文以沉积岩石学、构造地质学、石油地质学、测井地质学等相关学科为基础理论,利用测井、钻井、录井、取心、试油、地化等资料对定边地区延10沉积特征、储层特征、成藏要素等进行研究,在综合分析了油藏控制因素基础上,对有利区块进行预测。
     论文取得以下主要成果与认识:
     (1)利用标志层、沉积旋回、岩性厚度对比等方法,将延10油层组划分为两个砂层组,并且在等时地层格架内进行精细划分与对比研究。
     (2)通过岩心观察、测井等资料综合分析,指出定边地区延10期间为辨状河沉积,主要发育的河道充填、洪泛平原微相,河道砂体在平面呈南北向条带状为主,局部地区河道在发生合并与分叉,形成了辫状或网状形态。
     (3)根据岩心常规薄片、铸体薄片以及压汞等分析资料研究,延10储层岩性以长石砂岩和岩屑长石砂岩为主。储层经过压实作用、压溶作用、胶结作用以及溶解作用,孔隙类型主要为粒间孔、粒间溶孔。储层非均质性强,以中孔低渗储层为主。
     在综合以上研究基础上,结合油藏形成主控因素以及钻井试油、测井解释成果,预测出Ⅰ类有利区块3个,Ⅱ类有利区1个,其中Ⅰ类有利区含油面积共35.24km2,地质储量共1241.5×104t,展示了定边地区延延10油层组具有良好的资源前景。
Dingbian area is located in the northwestern of Shanbei Slope Belt, acrossTianhuan Syncline in Ordos Basin. Jurassic Yan'an Formation, as one of the main oillayer in this region, is small in size and relatively dispersed in distribution. Yan'anFormation was divided into 10 oil layers.Yan 10, with broad deposition, enjoys stabledistribution, with strong heterogeneity. In recent years, the exploration of Yan 10reservoir in Dingbian area had gone through a breakthrough. In order to clarify the oilbed distribution of Yan 10 reservoir, it is essential to apply research on the reservoircharacteristics and prediction on favorable zones.
     Taking sedimentary petrology, structural geology, petroleum geology, geologicallogging and other related subjects as theory foundation and using logging, drilling,logging, coring, geochemistry and other methods to do research on sedimentarycharacteristics, reservoir characteristics and accumulation factors, this papercomprehensive analysis controlling factors of reservoir and predicts favorable blocks.Obtain the following main achievements and know:
     (1)Using sign layer, cycle of sedimentation, lithology thickness contrast andother methods, Yan 10 is divided into two sand layer, and fine division and correlationstudies in etc stratigraphic framework.
     (2)Through observing cores, logging data and other related materialcomprehensive analysis, come to a conclusion that Yan 10 is braided riversedimentation, mainly development river filling, floodplains microfacies. Channelsand body is mainly showing a north-south extent band in plane. In some areas, riversin the event of mergers and branches form a braided or mesh patterns.
     (3)According to conventional thin core, cast, and mercury and other analysisdata, the reservoir of Yan 10 is mainly composed of litchis arkoses and arkose,and hasundergone compaction, pressolution, cementation and dissolution, The main pore is intergranular porosity and intergranular dissolution porosity. Heterogeneity isrelatively strong. Yan 10 is a reservoir bed which belongs to mid-porosity and lowpermeability.
     Based on the above research in comprehensive, combing controlling factors ofreservoir formation and the test of oil drilling, logging interpretation result, Predictedthree favorable blocks of classⅠand one of classⅡ. ClassⅠfavorable area in whichthe oil area of 35.24km2, geological reserves were 1241.5×104t, Shows the oil layer ofYan 10 in DingBian area has a good resource prospect.
