AI Technical Summary

Problems solved by technology

The screw pump has high efficiency and large displacement, but the investment cost is relatively high
Considering from a certain angle alone, it is impossible to make a reasonable choice
Generally speaking, artificial lift is affected by many factors such as economic benefits, operability, and reservoir conditions, and it is not possible to simply consider one aspect and lose sight of the other

Abstract

The invention relates to the technical field of submarine natural gas hydrate resource development engineering, and in particular to a method for optimally selecting artificial lift pumps in hydrate exploitation. According to the method, comparison and analysis are carried out on common artificial lift pumps by combining various factors in practical exploitation process on the basis of a fuzzy mathematic theory and an analytic hierarchy process, and optimal selection is carried out on the artificial lift pumps in hydrate exploitation, so that optimal selection of artificial lift exploitation pumps in natural gas hydrate exploitation is realized.

Description

technical field [0001] The invention relates to the technical field of marine natural gas hydrate resource development engineering, in particular to an optimal method for artificial lift pumps in hydrate exploitation. Background technique [0002] As a new type of energy, natural gas hydrate is a potential energy source with abundant reserves, wide distribution range and high energy density. The research on the exploitation of hydrate resources has become an international hot issue. However, the development of global hydrate resources is still in the trial mining stage in some areas, and there is still a long way to go before industrialized mining. [0003] At present, my country has accelerated the pace of research and accelerated the exploration and development of marine natural gas hydrate resources. In traditional offshore oil and gas extraction, the extraction methods include self-injection oil recovery and artificial lift oil recovery, and artificial lift includes rod...
