Physical and Chemical Geotechnologies

Purpose

Simulate physical and mechanical processes of the bottom layer, arising during at the development of gas hydrate deposits with using jet technology.

Methodology

The research was conducted by simulating of the bottom array behavior with methods of finite elements. The basic dependences in the thermobaric balance of the deposit are determined.

Findings

Software products on the basis of finite element methods for modeling the process of gas hydrate deposits development of the Black Sea are analyzed. The simulation of the basic geomechanical processes taking place in the gas hydrate-containing bottom massif with its developing jet technology is carried out. The basic technological parameters of the model in the array thermobaric equilibrium are established. The technological parameters dependencies of the jet technology on the bottom gas hydrate deposit development are determined. A graduation is made on the height of the hydrated deposit during the development, taking into account the hydrostatics of the surrounding rocks. The ecological assessment of the proposed solutions confirms the feasibility of their implementation of the Black Sea bottom, namely in the paleorossi river Dnipro. They contain the researches, which were conducted within the project GP – 489, financed by Ministry of Education and Science of Ukraine.
