Abstract
There are three types of faults in Block T121-4 of Aonan Oilfield, among which the faults developed from the early Qingshankou and terminated in the Third member of Nenen are the main channels for oil-gas migration. The pre-stack inversion shows that the lame impedance slice can well reflect the reservoir morphological characteristics and the channel characteristics are obvious. During the deposition period from HIIto HI, the water body changed from deep to shallow, the sedimentary facies transitioned from lakes to deltas, and underwater shunt channels were favorable reservoirs. The formation testing results show that the distribution of oil-gas is closely related to faults and sand bodies, and is the main controlling factor of reservoir formation. The main methods of oil-gas migration are vertical migration and short- distance lateral migration. If the fault-sand coupling relationship is good, oil-gas accumulation can be obtained. The reservoir anatomy shows that there are mainly two types of reservoirs in Heidimiao reservoir in the study area, namely structural reservoir and structural lithologic reservoir.
