The genetic classifications of the igneous rock reservoir in block Luo 115 are intergranular microporehornfels, condensate blowhole-solutional void diabase, condensate edging, condensate diabase edgingand center zone. The condensate diabase zone can be divided into horizontal, vertical and reticulatedfractures and so on according to the fracture occurrence. The conceptual model of reservoir in workingarea is constructed according to the genetic types of reservoir and the distribution rule of different fractureoccurrence and type. It can be divided into Z1, Z2, Z3 and Z4 zones vertically and PI, PII and PIII zoneshorizontally. Combined with the classification of the diabase invasion stages of block Luo 151, thefavorable reservoir can be predicted in the working area.
The genetic classifications of the igneous rock reservoir in block Luo 115 are intergranular microporehornfels, condensate blowhole-solutional void diabase, condensate edging, condensate diabase zone canging into horizontal, vertical and reticulated fractures and so on according to the fracture appearance.
