Traditional eai solutions integrate different application systems from the data source layer 傳統的eai解決方案主要從應用系統的數據層著手,對異構系統的數據源進行集成。
Jdbc 3 . 0 frees the developer from this concern because the data source layer is now responsible for caching prepared statements Jdbc 3 . 0讓開發人員不再為此擔心,因為數據源層現在負責為預備語句進行緩存。
Analysis of petroleum geology , reservoir types and distribution in lujiapu depression indicates that : the forming and distribution of reservoirs had been controlled by source area , source - reservoir relationship , petrophysical characteristics , sedimentary facies and secondary structure , and oil is most abundant in reservoirs around hydrocarbon kitchen ; the upper member of jiufutang formation which was entrained or embedded in the main oil source layer has well developed reservoir and good petrophysical property and is the principle oil - bearing interval ; the mid - fan and fan delta front of nearshore submarine fan is the most favorite facies ; the steep slope of the depression mainly consists of structural reservoirs , the slope belt mainly consists of structural - lithologic and updip pinchout reservoirs , the depressed belt mainly consists of lenticular lithologic reservoirs 摘要對陸家堡凹陷油藏形成的石油地質條件、已知油藏類型及分布的分析認為:生油區、生儲配置關系、儲集物性、沉積相帶和二級構造帶控制了油藏的形成和展布,其中圍繞生油洼陷的油藏含油最豐富;夾持或嵌入主要生油層中,儲層發育、儲集物性又相對較好的九佛堂組上段是主要含油層段;近岸水下扇的扇中和扇三角洲前緣是最有利的相帶:凹陷的陡坡帶以構造油藏為主,斜坡帶以構造巖性及儲層上傾尖滅油藏為主,深陷帶主要為透鏡狀巖性油藏。
