| Abstract: |
| The NE-NNE orienting pattern of injection-to-production wells is preponderant in practice in offshore Lüda Oil Field, Bo Hai. This orientation is discrepant with the past standpoint that the Oligocene Dongying sand-body reservoirs were regarded as NW-SE distribution. It is shown that the Fault Liaoxi-1 with dextral strike-slip is comprised of connecting arcuate faults so that the distribution of reservoirs is controlled by the structural transfer zone. This cognition is supported by seismic attributes and heavy minerals analysis. The plots of sedimentary system that are re-established by major oil formation groups have demonstrated the reservoirs with NE-NNE distribution in this oil field. This recognition is significant for reservoir elaboration, flood-out rule analysis and remaining-oil development. |
