Abstract

Abstract:

In recent years, significant breakthroughs of hydrocarbon exploration have been achieved in deepwater area off the southern Pearl River Mouth Basin. They helped to verify this area has a favorable geology condition for hydrocarbon. Deepwater area offshore off Xisha Island lies in the same structural belt as the deepwater area off the southern Pearl River Mouth Basin, and they have similar structure and sedimentary evolution history. Through analogy and geological research, the authors conclude that there is a good prospect for hydrocarbon exploration in deepwater area offshore off Xisha. Based on the coherence technology, results of different generations of the technology were compared with the high resolution seismic data acquired in recent years. The coherence technology was applied in hydrocarbon exploration in this deepwater area. First, the coherence technology is very sensitive to discontinuity in seismic data, and the faults can be effectively identified. On a coherence slice, the fault trend and the interaction cutting relation are very clear. Secondly, the coherence technology emphasizes amplitude strengthening and marginal detection and can be used in deepwater channel identification and description. On a coherence slice, the whole size of a channel, meandering characteristic, lateral erosion are distinct, and the edge of the channel appears as a discontinuity belt. Moreover, the core of the reef appears uniform (with similar seismic reflection characteristics); and seismic reflection clutter occurs at the edge of the reef. So, a reef can be identified by the coherence technology. Finally, there is an obvious difference between inner and outer layers of a volcanic rock. The coherence technology was applied to identify a volcanic rock. On a coherence slice, the volcanic rock developing area shows obvious weak coherence and there were radial-type faults in the core center of the volcanic rock.
