【摘要】 济阳坳陷沾化凹陷罗 1 51块火成岩油藏储集层成因类型可分为晶间微孔隙角岩、冷凝气孔—溶蚀孔辉绿岩冷凝边、冷凝缝辉绿岩体边缘及中心带 ,其中冷凝缝辉绿岩带根据其裂缝产状进一步分为水平、垂直和网状裂缝等类型。根据储集层成因类型及不同产状类型裂缝的分布规律 ,建立了工区储集层概念模型 ,纵向分为 4个带 ;平面分为 3个区。结合罗 1 51块辉绿岩体侵入期次的划分 ,可对工区有利储集层分布进行预测。照片 2图 2参 3 (邹冬平摘 )更多还原

【Abstract】 The generation materials of the reservoirs in Luo 151 igneous oil pools consist of intergranular micropore hornfels, condensate blowhole solution void diabase and condensate edge and the edge and center of the condensate seam diabase, of which the condensate seam diabase zones are divided into horizontal, vertical and reticulated cracks according to fracture occurrence. Based on the above, a conceptual model of reservoir is generated, which is vertically divided into Z 1, Z 2, Z 3 and Z 4 belts; and horizontally P Ⅰ, P Ⅱ and P Ⅲ areas. Combined with the division of intruding periods of Luo 151 diabase body, favourable reservoir distribution in the working area can be predicted.更多还原
