The invention provides a method and system for calculating the original dip angle and the original inclination of a sedimentary structure. The method for calculating the original dip angle comprises the following steps: obtaining a base level normal line and a sedimentary structure surface normal line; The angle between the normal line of the datum plane and the normal line of the sedimentary structure plane and the horizontal plane is obtained, and the angle between the normal line of the datum plane and the normal line of the sedimentary structure plane is calculated, which is the original dip angle of the sedimentary structure plane. The calculation methods of the original dip are as follows: obtaining the original dip angle of the sedimentary tectonic plane; According to the original dip angle of the sedimentary structure surface, the original dip angle of the sedimentary structure is obtained. The technical proposal provided by the invention calculates the original dip angle and the original inclination of the sedimentary structure by using the relationship among the base level, the horizontal plane and the sedimentary structure plane, and provides a basis for predicting the development trend of the sand body and finding the favorable oil and gas reservoir.
Description
technical field [0001] The invention belongs to the technical field of sedimentary structure data processing, and in particular relates to a calculation method and system for the original dip angle and original dip of the sedimentary structure. Background technique [0002] The paleo-sedimentary structure of strata is of great significance to the exploration and development of oil and gas. Through the occurrence of sedimentary structures (mainly referring to oblique bedding), the paleocurrent direction of sedimentary basins can be judged, so as to predict the development trend of sand bodies and find favorable oil and gas reservoirs. [0003] In geology, the important factors of the occurrence of sedimentary structures are dip and dip, where dip refers to the angle formed by a straight line or plane and a horizontal line or horizontal plane, or the angle formed by a straight line and its projection on a plane; The straight line perpendicular to the trend line and drawn down...
