Important Significance

Deep-water fan systems have become the main body of international oil production and reserves growth. It has important significance of science and production to study the sedimentary characteristics of deep-water fans. On the basis of a large number of literature research, this paper summarizes the research history and current situation of the deep-water fan. For several kinds of sedimentary microfacies in the fan, typical sedimentary characteristics and seismic combination structures are identified, including the composition, sedimentary structure, granularity, contact relation, seismic reflection and so on. These results are hoped to be helpful for sedimentary microfacies discrimination and research of deep-water fan.

The distinction between turbidites, contourites and hemipelagites in modern and ancient deep-water systems has long been a matter of controversy. This is partly because the processes themselves show a degree of overlap as part of a continuum, so that the deposit characteristics also overlap. In addition, the three facies types commonly occur within interbedded sequences of continental margin deposits. The nature of these end-member processes and their physical parameters are becoming much better known and are summarised here briefly. Good progress has also been made over the past decade in recognising differences between end-member facies in terms of their sedimentary structures, facies sequences, ichnofacies, sediment textures, composition and microfabric. These characteristics are summarised here in terms of standard facies models and the variations from these models that are typically encountered in natural systems. Nevertheless, it must be acknowledged that clear distinction is not always possible on the basis of sedimentary characteristics alone, and that uncertainties should be highlighted in any interpretation. A three-scale approach to distinction for all deep-water facies types should be attempted wherever possible, including large-scale (oceanographic and tectonic setting), regional-scale (architecture and association) and small-scale (sediment facies) observations.

Following the analysis of cores, outcrops, well log, and seismic sections, we have studied the seismic reflection configuration and depositional history of the hydrocarbon-rich Yanchang Formation in the Ordos Basin. We divided the seismic reflection configurations into five types: subparallel reflection, parallel reflection, tangential progradational reflection, shingled progradational reflection, and chaotic reflection. Based on our study results, we concluded that the slopes exhibit differences in the different regions of the Ordos Basin during the sedimentary period of the Yanchang Formation: The slope with the largest gradient of approximately 10°–20° occurred in the southwestern basin, followed by the northwestern basin (with a slope of approximately 1.6°–3.3°), but the slope was relatively gentle in the northeastern basin (approximately 0.8°–1.2°). We also found that the paleocurrent direction of the basin mainly includes two directions: The paleocurrent direction of the southwest region is 186°–259°, which indicates the provenance came from the southwestern region, whereas the paleocurrent direction of the northeast region is 10°–79°, which indicates that the provenance came from the northeastern region. In addition, the Ordos Basin was under isostatic subsidence as a whole during this period, and its sedimentary infilling evolution underwent five stages: the initial depression, intense depression, progradational filling, uplifting and denudation, as well as shrinking and extinction stages, just corresponding with the Chang 10-Chang 9, the Chang 8-Chang 7, the Chang 6-Chang 4+5, the Chang 3-Chang 2, and the Chang 1 depositional age, respectively.

Using core analysis, thin slice identification, logging analysis and seismic interpretation, systemic study upon sedimentary types, sedimentary facies, physical and oil bearing properties of each sedimentary microfacies, etc presenting in underwater alluvial fan of Kerqin oilfield of Kailu basin in China, is performed. To identify sedimentary characteristics of underwater alluvial fan and determine its oil bearing property so as to develop this type of reservoir reasonably and effectively. Underwater alluvial fan comprises of 5 kinds sedimentary facies: clastic flow, high density flow, low density flow, overflow and river channel sedimentation. Further division includes three sub-facies, i. e. tail, body and front part of underwater alluvial fan, among which braided structure of body part features favorable accumulation and oil bearing properties. Underwater alluvial fan is formed from the double action mechanisms of gravitational flow and traction flow. Body microfacies are primary oil bearing play and braided channel is the main future development target.
