ABSTRACT: By reviewing the development of “three-high” oil and gas well testing
technology of Sinopec in recent years, this paper systematically summarizes the
application of “three-high” oil and gas well testing technology of Sinopec in
engineering optimization design technology, and high temperature and high
pressure testing technology, high pressure and high temperature transformation
completion integration technology. Major progress has been made in seven
aspects: plug removal and re-production technology of production wells in high
acid gas fields; wellbore preparation technology of ultra-deep, high-pressure,
and high-temperature oil and gas wells; surface metering technology; and
supporting tool development technology. This paper comprehensively analyzes the
challenges faced by the “three-high” oil and gas well production testing
technology in four aspects: downhole tools, production testing technology, safe
production testing, and the development of low-cost production test tools. Four
development directions are put forward: 1) Improve ultra-deep oil and gas testing technology
and strengthen integrated geological engineering research. 2) Deepen oil and gas well integrity evaluation
technology to ensure the life cycle of oil and gas wells. 3) Carry out high-end, customized, and intelligent
research on oil test tools to promote the low-cost and efficient development of
ultra deep reservoirs. 4) Promote the fully automatic
control of the surface metering process to realize the safe development of “three-high” reservoirs.
