Abstract

The invention belongs to the technical field of natural gas hydrate exploitation, and discloses a simulation operation experiment system suitable for a natural gas hydrate wellhead gas production tree. Comprising a water pool, a bottom vibration system, an oil pipe, a gas production tree body, a lateral fluctuation simulation system, an underground robot control panel, a sensor, a pressure meter, a flow meter, a hydrate transport pump, a natural gas hydrate synthesis device, a data analysis system and a control system. Wherein the bottom vibration simulation system is located at the bottom of the pool; the lateral fluctuation simulation system is located at the edge of the pool. And the underground robot operating system is connected with the wellhead control system. The device can simulate the operation condition analysis of the wellhead gas production tree system under the conditions of transverse fluctuation and axial vibration, and is more suitable for the real production environment of deep water. Control of an underground robot control system on a wellhead gas production tree can be simulated, the control precision under complex working conditions can be verified, and real-time adjustment and error correction are achieved.

Description

technical field [0001] The invention belongs to the technical field of natural gas hydrate exploitation, and in particular relates to an experimental system suitable for the simulated operation of a natural gas hydrate wellhead gas tree. Background technique [0002] The ocean is a huge cornucopia for future energy development, and the deep sea is the main battlefield for development. In marine energy, natural gas hydrate, as an important unconventional natural gas energy, is the frontier of scientific and technological innovation and the direction of key technical research, and is an important replacement strategic energy in the future. It is of great significance to break through the key technologies of natural gas hydrate exploration and development and realize commercial exploitation as soon as possible. [0003] The downhole production system is a key node in the process of natural gas hydrate exploitation. Its main function is to effectively control the working pressu...
