Abstract

The invention relates to an early monitoring device for hydrate blockage of a deep water gas well production pipeline. The early monitoring device comprises a data collecting and transmitting system, a data analyzing and processing system and an automatic hydrate inhibitor injection system. The data collecting and transmitting system monitors temperature and pressure data in the production pipeline in real time and transmits the monitoring data to the data analyzing and processing system. The data analyzing and processing system stores, analyzes and processes the monitoring data, calculates and analyzes the natural gas hydrate blockage condition in the production pipeline and sends out an early warning signal and a hydrate inhibitor injection instruction. The automatic hydrate inhibitor injection system is arranged on a platform and injects hydrate inhibitor into the production pipeline according to the instruction sent by the data analyzing and processing system. By means of the early monitoring device, early monitoring can be achieved for the hydrate blockage position and the blockage severity degree in the production pipeline, sufficient time is provided for field workers to take the hydrate inhibitor injection measure, and more serious blockage conditions are avoided.

Description

technical field [0001] The invention belongs to the technical field of offshore oil and gas development, and in particular relates to an early monitoring device and method for hydrate blockage of a deep-water gas well production pipeline. Background technique [0002] With the continuous deepening of deep-water oil and gas exploration and development in the South my country Sea, a number of deep-water oil and gas fields have gradually entered the production and development stage. For this reason, it is necessary to install a large number of production pipelines composed of underwater production systems, submarine pipelines and riser systems to provide oil and gas production. aisle. [0003] figure 1 It is a typical deep-water gas well production system, mainly composed of wellbore (tubing) 101, subsea tree 103, subsea manifold 104, subsea pipeline 107, riser 110 and oil and gas processing platform (FPSO) 112. The wellbore 101 is connected to the subsea manifold 104 through ...
