Abstract

The invention relates to a stratigraphic sedimentation process plane periodicity analysis method, relates to the technical field of fundamental geology study, and is to obtain periodic features of anaccommodation space plane change trend and plane periodicity features of a sedimentation speed change trend so as to quantitatively describe the periodic features of the plane change trend of the stratigraphic sedimentation process. The method comprises a step of obtaining the periodic features of the accommodation space plane change trend and a step of obtaining the periodicity features of the sedimentation speed change trend. The method can obtain the plane periodic change features of the stratigraphic sedimentation process of a measurement area and realizes a purpose of carrying out quantitative analysis on plane periodical rules of the stratigraphic sedimentation process.

Description

technical field

[0001] The invention relates to the technical field of basic geological research, in particular to a plane periodic analysis method for stratum deposition process. Background technique

[0002] The existing technology can obtain the vertical periodic change process of the stratum deposition process in the stratigraphic framework; or study the planar periodicity of the deposition process through the change of facies belt in different regions, the migration of subsidence center and deposition center, and does not use quantitative analysis method. However, there is no method at present that can quantitatively analyze the planar periodic variation characteristics of the stratigraphic deposition process in a certain area based on the stratigraphic division and comparison at equal time intervals.

Embodiment Construction

[0029] The present invention will be further described below in conjunction with accompanying drawing.

[0030] figure 1 It is a flow chart of a plane periodicity analysis method for stratum deposition process in an embodiment of the present invention; as figure 1 As shown, the present invention provides a kind of plane periodical analysis method of stratum deposition process of different acquisition parameters, and this method comprises the following steps:

[0031] The first step is to obtain the data points of the target block, and obtain the original stratum deposition thickness of each data point in the equidistant stratigraphic unit. Wherein, the target interval for selecting data points is continuous deposition without stratum denudation, there are at least three data points, and the three data points are not on the same straight line.

[0032] Further, the data point can choose drilling or outcrop data.

[0033] Furthermore, the original stratum deposition thickness...
