Estuary dam geometrical morphology measuring method

Abstract

The invention discloses an estuary dam geometrical morphology measuring method. The method includes the following steps that firstly, a prototype geologic model is determined according to measuring region geological data, a physical model is established according to the similarity theory of sedimentary physical simulation, an experimental scheme is designed accordingly, an experiment is carried out on the basis of the experimental scheme and the sedimentation process is controlled; secondly, the sedimentation result is researched through a section cutting method, the position of an estuary dam is determined, length and width data of the estuary dam and the extended distance of the lake shoreline are measured, a planar distribution diagram of the estuary dam is drawn, and thickness data of the estuary dam are measured in combination with the section; thirdly, linear correlation analysis is conducted on the obtained length-thickness and length-width data of the estuary dam; fourthly, modern sedimentation estuary dam length and width data measured on the basis of satellite photos are obtained, statistical analysis is conducted on the modern sedimentation estuary dam length and width data, and a research area estuary dam length-width empirical formula is established by synthesizing water tank simulation and modern sedimentation measuring results. The method has the advantage of being capable of guiding exquisite configuration anatomy of a work area estuary dam and can be widely applied to the technical field of reservoir description.

Description

technical field [0001] The invention relates to the technical field of reservoir description, in particular to a method for measuring the geometry of mouth bars. Background technique [0002] Sedimentary physical simulation technology (also known as flume simulation) originated at the end of the 19th century and is an important branch in the field of sedimentology research. Nowadays, it has been increasingly applied in the process of oil and gas field exploration and development, solving the problems of sedimentology theory and production practice, including Specific practical issues such as the formation and distribution of sedimentary systems, the formation process and evolution of sand bodies, the internal architecture of sand bodies, the heterogeneity of sand bodies, and the distribution of remaining oil. Foreign scholars have simulated various sedimentary systems through experiments, and domestic scholars have also done a lot of research. [0003] The theory of reservo...

AI Technical Summary

Problems solved by technology

Different scholars have studied the length and width data of the mouth bar from different angles, and the results obtained are very different, which shows that the understanding of the actual scale of the mouth bar is controversial
