System for monitoring components of shaft fluid of H2S/CO2-containing gas field and analysis method thereof

Abstract

The invention belongs to the field of oil gas and oil well development, discloses a system for sampling and monitoring components of shaft fluid of a gas field and particularly relates to a system for sampling and monitoring components of the shaft fluid of the gas field and a sampling and analysis method thereof, which are designed aiming at environmental characteristics of a H2S / CO2-containing gas field. A sampling process of a sampler of a gas well is safer, an experimental process is more accurate and quicker, and the application pressure range is wider and safer, and an experimental result of researching the change of high-content hydrogen sulfide gas components is more accurate; and a device is safe and reliable. Through the system and the method, the problems that fluid pressure cannot be obtained and fluid deposit in the shaft cannot be predicted because the measurement cannot be performed in the gas field containing high content of H2S / CO2 can be solved and theoretical basis is provided for a gas well capacity design, production parameter optimization and the formulation of technical measures.

Description

technical field [0001] The invention belongs to a gas field wellbore fluid composition sampling monitoring system in the field of oil and gas oil well development, and particularly relates to a 2 S / CO 2 Gas field wellbore fluid composition sampling and monitoring system designed for gas field environment characteristics and its sampling and analysis methods. Background technique [0002] With the continuous development of my country's national economy, the country's demand for energy is also increasing. Improving the proportion of green energy natural gas in the energy structure as soon as possible, increasing mining efforts, and optimizing China's energy structure are the core of my country's oil and gas resource development strategy. It is essential to effectively solve energy supply security and ecological environment protection, and achieve sustainable economic and social development. is of great significance. [0003] At present, for the exploitation of conventional n...
