    Abstract: Identifying remaining oil distribution is an essential study at the Third District in North Saertu of the West Block in Daqing Oilfield. This field is known as a flooding fine potential tapping demonstration zone, characterized by a long-developing history and complex well history. Based on tectonic features and sedimentary characteristics of the study area, the methods of facies controlled reservoir 3D geological modeling and numerical simulation are used in the process of establishing the geological 3D static model. In this paper, we summarized the causes and distribution law of remaining oil in the study area by using the method of fine reservoir numerical simulation to provide a reliable basis for the development and adjustment of the oil field. In combination with fine exploration such as water drive fracturing, water plugging, reperforating and injection-production segment, the recoverable reserves recovery rate could be effectively increased. Estudio de la distribución del remanente de petróleo en el bloque oriental del tercer distrito, en el norte de Sartu, China ResumenLa identificación de la distribución del remanente de petróleo es un estudio esencial en el tercer distrito del norte de Sartu, que corresponde al bloque occidental del campo petrolífero de Daqing. Este campo es conocido como una zona ejemplar para aprovechar el potencial de explotación por inundación y que se caracteriza por una historia compleja y de largo desarrollo de sus pozos. Con base a las características tectónicas y sedimentarias del área de estudio se utlilizaron los métodos de modelado geológico 3D en depósitos con facies controladas y la simulación numérica en el proceso de establecer el modelo geológico 3D estático. En este artículo se establecen las causas y la ley distributiva del remanente de petróleo en el área de estudio a través del método de simulación numérica de depósitos de alta resolución que provea una base fiable para el desarrollo y ajuste del campo petrolero. Con la combinación de métodos de exploración como la fractura dirigida con agua, taponamiento acuático, reperforación y segmentos de inyección-producción, el índice de recuperación de reservas podría incrementar efectivamente.

    Abstract: A catastrophic landslide hit Mount Fugui, Diexi Township, Mao County, Sichuan Province at 05:38:58 on June 24, 2017. This landslide buried Xinmo village, caused 83 deaths and resulted in enormous loss to people’s lives and properties. The Xinmo landslide was an earthquake-induced shattered mountain formed in the epicenter zone of the 1933 Ms7.5 Diexi earthquake (with an intensity of level X) and the strong motion zone of the Ms8.0 Wenchuan earthquake (with an intensity of level IX).The landslide mass cut out and slid from a high position, loaded continuously and accumulated at the top of the slope body. Subsequently, the landslide mass was transformed into avalanche debris, which clogged Songpinggou and thus formed a landslide dam, indicating a typical chain disaster of avalanche debris triggered by a ridge-top landslide. The total volume, elevation difference and horizontal distance of the landslide were 1637.6×104m3, 1200 m and 2800m, respectively. The authors of this study identified the disaster-formation mechanism of the Xinmo Landslide based on a field geological survey, remote sensing satellites and the other means. The authors analyzed the disaster characteristics of the landslide source zone, avalanche debris zone and accumulation zone, numerically simulated and comparatively studied the whole process of the Xinmo Landslide movement using DAN-W, i.e., dynamic landslide software, and multiple groups of rheological models. The research findings indicated that the friction model was able to favorably simulate the movement characteristics of various phases of the Xinmo Landslide; this landslide lasted approximately 120 s and had a maximum velocity of movement of 74 m/s. As a result, the friction model and its parameters can be used in similar studies on dynamic disaster effects of ridge-top rock landslides.
