渤海湾盆地南堡凹陷碳酸盐岩潜山油气成藏条件优越,油气富集受地层、构造、储层等多重因素控制,优质储层发育和分布是研究的重点。通过对钻井、测井、岩心等各项资料深入分析,明确了南堡凹陷碳酸盐岩储集空间以溶蚀孔洞为主,主要储层类型为裂缝-孔洞型,裂缝是沟通孔洞的重要通道;碳酸盐岩沉积相带、成岩作用(包括岩溶)、构造作用是碳酸盐岩潜山优质储层发育的主控因素。其中有利沉积相带是储层发育的基础,有利的成岩后生作用是储层发育的保障,有利的构造作用是储层发育的关键。通过细分地层组段开展地震地质储层综合预测,显著提高了储层预测结果的准确性。
渤海灣盆地南堡凹陷碳痠鹽巖潛山油氣成藏條件優越,油氣富集受地層、構造、儲層等多重因素控製,優質儲層髮育和分佈是研究的重點。通過對鑽井、測井、巖心等各項資料深入分析,明確瞭南堡凹陷碳痠鹽巖儲集空間以溶蝕孔洞為主,主要儲層類型為裂縫-孔洞型,裂縫是溝通孔洞的重要通道;碳痠鹽巖沉積相帶、成巖作用(包括巖溶)、構造作用是碳痠鹽巖潛山優質儲層髮育的主控因素。其中有利沉積相帶是儲層髮育的基礎,有利的成巖後生作用是儲層髮育的保障,有利的構造作用是儲層髮育的關鍵。通過細分地層組段開展地震地質儲層綜閤預測,顯著提高瞭儲層預測結果的準確性。

Hydrocarbon accumulation conditions of carbonate buried-hill are favorable in Nanpu Sag , and hydrocarbon enrichment is controlled by multiple factors like stratigraphy , structure and reservoir .Development and distribution of quality reservoir are the focus of the research .In-depth analysis of drilling ,logging,core and other data reveals that the main reservoir type is fractured-vuggy carbonate reservoirs in Nanpu Sag ,with dissolution pores and vugs as the dominant reservoir space and fractures as the main channels connecting the pores and vugs .Carbonate sedimentary facies zones ,di-agenesis ( including karstification ) ,and tectonic process are the main factors controlling on the development of high-qual-ity carbonate buried-hill reservoirs.The favorable sedimentary facies are the basis of reservoir development ,the favorable diagenetic epigenesis is the guarantee of reservoir development and the favorable tectonic process is the key to reservoir development .The precision of reservoir prediction is significantly improved through comprehensive seismic and geological reservoir prediction based on layer subdivision .
