Problems solved by technology

Or it can be confirmed that the outcrop belongs to the target research interval, because the location of the outcrop cannot be quantified
Only single-section research can be done after the sample is obtained, and multi-section horizontal comparison cannot be carried out

Embodiment

[0038] A research method based on the characteristics of carbonate rock sedimentary cycles with multiple outcrops includes the following steps (such as Figure 9 shown):

[0039] Step 1: Select a suitable field outcrop profile.

[0040] Fully investigate the development of strata in the study area, and learn from previous research results to have a preliminary understanding of the paleogeomorphology, paleoenvironment, and structural characteristics of the study area. Select representative outcrops in the study area. According to previous outcrop research experience, the selection of outcrops should be based on the following criteria: ① The characteristics of sedimentary types are obvious; The selected type has good comparability with the oil field; ④The traffic conditions are as convenient as possible.

[0041] The second step: if Figure 1-2 As shown in , stratum boundaries, marker layers, and special lithology are taken as constraints.

[0042] Collect the drilling, logg...

Abstract

The invention discloses a method for researching the sedimentary cycle characteristics of carbonate rocks based on multiple outcrops, comprising the following steps: S2: comparing the sedimentary cycle characteristics of multiple outcrop sections in the field; S3: processing part of the strata by identifying the weathering crust in the outcrop S4: Identifying the quartz sandstone in the field outcrop to deal with the anomalous lithology and sedimentation of some strata; S5: Vertical fitting of multi-section and multi-sampling point ascending order method; S6: Determining the characteristics of the sedimentary cycle of the field outcrop section. The scheme division of the present invention is based on comprehensive analysis of sedimentology and statistics. For some limitations faced in field outcrop research, a scientific and effective fitting method is proposed, and according to the top-bottom boundary of the target layer, the boundary of the marker layer, the boundary of the sedimentary cycle, and the boundary of special lithology, multi-section and multiple sampling points Fitting is carried out, and good experimental results have been obtained in practice. Therefore, it is conducive to the large-scale promotion of the method by fitting.

Description

technical field [0001] The invention belongs to the technical field of geology and sedimentology, and in particular relates to a research method for the characteristics of carbonate rock deposition cycles based on multiple outcrops. Background technique [0002] Outcrops are the most intuitive, real, and detailed data of sequence stratigraphy, and have the characteristics of high resolution that drilling and seismic data do not have. On the basis of reconstruction and deformation, those outcrops that are fully exposed, can be traced continuously, and are easy to observe should be selected for field outcrop reconnaissance, stratification, and measurement, and sequence boundaries, systems tracts, condensed beds, and sedimentary facies markers should be collected for high-level analysis. High resolution sequence stratigraphy interpretation. [0003] In the current research situation, in field surveys, it is often encountered that the outcrop profile is not fully exposed. Or i...
