“…Previous field investigation suggested that sand debris flows and slump gravity flows occurred in the steep slope zone near the border faults in the Sangyuan and the Wangjiagou sections (Er et al, ; C. Liu, Yu, et al, ; Wei et al, ). In recent years, several models of SGF deposits in deep water have been developed for lacustrine basins (L. Liu, Chen, et al, ; J. P. Liu, Xian, et al, ). According to previous studies in recent years, the subaqueous extension of the distributary channels in deep water was controlled by hyperpycnal flows (Xian et al, ; Yang et al, ).…”

Hyperpycnites are extrabasinal turbidites related to hyperpycnal flows which form during river floods. Compared to intrabasinal turbidite systems in deep marine or lacustrine settings, hyperpycnites in shallow lakes settings are not understood. In this work, we studied the typical sedimentary characteristics of shallow lacustrine hyperpycnal flow deposits in outcrops of the Luanping Basin, Northeast China. Based on the sedimentary architecture and analysis of the facies associations in these outcrops, the hyperpycnites can be classified into the following three types: (a) bedload-dominated erosional channel deposits, (b) bedload-and suspended-loaddominated channel-to-lobe transitional deposits, and (c) suspended-load-dominated lobe deposits. The erosional channels in proximal locations are filled by mud clasts, parallel-laminated sandstones, massive sandstones, cross-bedded sandstones, massive siltstones, and mudstones. The channel-to-lobe transitional deposits in a middle location are composed of parallel-laminated sandstones, cross-bedded sandstones, mud clasts near internal erosional surfaces, ripple cross-bedded sandstones, massive siltstones, and mudstones. The lobe deposits in distal locations are composed of ripple cross-bedded sandstones, massive siltstones, and mudstones. The sedimentary process of the shallow lacustrine hyperpycnal flows shows obvious response to periodic flood energy fluctuations. Gentle slope, small capacity of flood discharges and semiarid paleoclimate may be the possible reason for the observed sedimentary architecture of the shallow lacustrine hyperpycnal flow deposits. Therefore, this study

“…Investigation of the sedimentological characteristics, sequence stratigraphy and reservoir formation of E 3 s 2 is based on the analysis of seismic data, well logging, and cuttings obtained from the Tianjin Branch of China National Offshore Oil Corporation. 3D post-stack seismic data covering approximately 630 km 2 and 2D seismic lines have a vertical resolution of approximately 15-30 m, and a frequency higher than 35 Hz (Liu et al, 2017). Furthermore, data from four boreholes were combined and applied in this study.…”

The Liaodong Bay area in northeast China has abundant hydrocarbon resources. The study area (referred to as D-1) is located in the southeast portion of the Liaodong Graben, a tectonic unit of Liaodong Bay, where the focus for exploration is on sandstone units in the Palaeogene Shahejie Formation. Here, hydrocarbons with an oil production capacity of 629 m 3 /day have been discovered in well D-1-2SA. The reservoir facies have been analysed by combining the cuttings, logging, seismic data, sedimentary facies, and sequence stratigraphy. In the sequence stratigraphic study, the second member from the base of the formation is divided into one third-and four fourth-order depositional sequences. The sedimentary facies include fan deltaic, braided river deltaic, and lagoonal systems. Seismic attribute inversion of the sequence framework, depositional models, and sediment distribution has been conducted for each system tract. The reservoirs facies in the D-1 area are characterized by medium to low porosity, and medium to low permeability. The development of reservoirs facies is related to the subaqueous depositional channels of the fan deltaic system with the best quality for hydrocarbon storage. These channels have strong root mean square amplitudes used for seismic attribute identification for reservoir targets. The formations of the source-to-sink system with granitic and metamorphic source rocks and relative distant transportation are considered to have the best potential for hydrocarbon reservoirs.

Fracture detection and in‐situ stress determination via well logs are important for exploration and exploitation of subsurface hydrocarbons. Cores, thin sections, and image logs are used to describe and interpret the subsurface fractures and in‐situ stress in the Paleogene Dongying sandstones in Nanpu Sag, Bohai Bay Basin, China. The maximum horizontal stress (SHmax) indicates a nearly east‐west trend according to the borehole breakouts and drilling‐induced fractures. Natural fractures in the Dongying sandstones are classified into: (1) open fractures and (2) closed fractures. The cement‐filled (closed) fractures are commonly detected by image logs as bright discontinuous sinusoidal waves due to resistive filling materials, while the open fractures are evident on image logs appearing as dark sine waves. The open fractures are of dominantly high dip angles, and the rose diagrams confirm the presences of two sets of fractures: northwest‐southeast and northwest‐southeast orientation. Fractures with strikes approximately parallel to the SHmax have good connectedness, making a significant contribution in hydrocarbon production. In addition, the oil‐bearing layers are mainly associated with the intervals with open fractures. The presence of natural fractures provides important pore spaces and fluid flow conduits. Insights can be provided into the subsurface fracture (natural and induced) detection and characterization using image logs.
