Landslide refers to the geological phenomenon that a geologic body on a slope slides down along a sliding surface integrally under the action of gravity. Landslide is essentially a mass motion in which the shear stress on the slip plane exceeds the shear stress resistance of the plane. The block is handled without the need for handling media and thus the landslide can be formed on land or under water in any unstable slope environment (i.e. underwater landslide mass).
Step 200: seismic profile features of a landslide wall construction and a toe construction of the underwater landslide body are each determined.
It can be understood that the landslide wall of the underwater landslide body comprises a rear wall and a left side wall and a right side wall, and the determined sign of the rear wall is that a series of plough-type normal faults and tensile minor faults are developed on the seismic section, and then a series of gliding blocks and rotating blocks are developed; the side wall is a lateral edge contact structure unit of the underwater landslide body, and the determined mark is a cliff and linear distribution characteristic on a seismic section. The toe of the underwater landslide body is influenced by the gravity extrusion of the landslide body, and the toe is determined to be marked by a back-impact fault which develops small folds and imbricate arrangement on the seismic section.
Step 300: and determining the seismic slice characteristics of the plane spread structure of the underwater landslide body.
The underwater landslide body is totally in a disordered reflection on a plane, and the determined mark is a concentric circular pressure ridge on the seismic slice.
In step 100 to step 300, in the case of a known underwater sliding mass, the seismic amplitude characteristics of the top surface structure and the bottom surface structure, the seismic profile characteristics of the slope wall structure and the toe portion structure, and the seismic slice characteristics of the plane spread structure are analyzed and summarized.
Step 400: and determining the spatial distribution of the underwater landslide body according to the core data, the logging data, the seismic amplitude characteristics, the seismic profile characteristics and the seismic section characteristics of the target block.
Specifically, based on the calibration results of the rock core and the logging data, the top and bottom surface structures, the landslide wall form, the toe characteristics and the plane spread range of the underwater landslide body are comprehensively considered, and finally the spatial spread of the underwater landslide body is comprehensively determined.
As can be seen from the above description, the embodiment of the present invention provides a method for determining the spatial distribution of an underwater landslide body, which includes determining the seismic amplitude characteristics of the top surface structure and the bottom surface structure of the underwater landslide body; determining respective seismic profile characteristics of a landslide wall structure and a toe structure of the underwater landslide body; determining the seismic section characteristics of the plane spread structure of the underwater landslide body; and determining the spatial distribution of the underwater landslide body according to the core data, the logging data, the seismic amplitude characteristics, the seismic profile characteristics and the seismic section characteristics of the target block. The method determines the spatial distribution range of the underwater landslide body based on the earthquake, the rock core and the logging data, improves the prediction precision of the underwater landslide body and further improves the oil-gas exploration deployment effect.
In one embodiment, the seismic amplitude signature of the top surface formation comprises: irregularities, poor continuity and moderate to strong amplitude;
the seismic amplitude signature of the subsurface formation comprises: good continuity and the presence of erosion grooves.
In one embodiment, the ramp wall construction comprises: a landslide back wall and a landslide side wall;
the seismic profile characteristics of the landslide backwall include: a series of plow normal faults and tensile minor faults;
the seismic profile features of the landslide sidewall include: scarps and linear distribution features;
the toe configuration has seismic profile features comprising: developing small fold and/or shingled lines of recoil fractures.
In one embodiment, the seismic slice features of the planar spread configuration include: concentric circular pressure ridge features.

The top surface structure is identified as the features of seismic data which are irregular, poor in continuity and medium-strong in amplitude; the identity of the subsurface structure is the presence of a continuous, eroded groove in the seismic data. In this embodiment, the top surface structure and the bottom surface structure of the underwater landslide body of the study interval N are determined based on the seismic data of the study interval N, as shown in fig. 3 and 4. The underwater landslide mass top surface structure is mainly characterized by irregularity, poor continuity and medium-strong amplitude in a seismic section (figure 4); the underwater landslide body bottom surface configuration has good continuity, common erosion grooves (fig. 4).
S2: and determining the landslide wall of the underwater landslide body.

In this embodiment, based on the seismic data of the study interval N, the rear wall and the left and right side walls of the underwater landslide body of the study interval N are determined, as shown in fig. 3, 4 and 5. A series of plow-type normal faults and tensile small faults (figure 5) are developed on the rear wall of the seismic section, lateral edge contact structural units (figure 4) are arranged on the side wall, and the relationship between the lateral edge contact structural units and surrounding undeformed strata is obvious due to the characteristics of unequal scarps and linear distribution.
S3: and determining the toe of the underwater landslide mass.
Specifically, the toe of the underwater landslide body is affected by the gravity extrusion of the landslide body, and is identified as a thrust fault on the seismic section developing a small fold and shingle-like arrangement. In this example, the toe of the underwater landslide mass of the study interval N is determined based on the seismic data of the study interval N, see fig. 3 and 6. The toe of the underwater landslide body is affected by gravity squeezing, and small-scale wrinkles and imbricated arranged recoil faults can be seen on the seismic section (figure 6).

In this embodiment, the underwater landslide body plane spread range of the study interval N is determined based on the seismic data of the study interval N, as shown in fig. 7. The underwater landslide mass is totally randomly reflected on a plane and shows typical concentric circle-shaped pressure ridge characteristics on a seismic slice (figure 7).
