Prof. Jingfu Zhang
Northeast Petroleum University, China
Research Area:
theory and technology of oil and gas well engineering
Research Experience:
Prof. Jingfu Zhang mainly engaged in drilling fluid,
completion fluid mechanics and chemistry, oil and gas well engineering mechanics research work:
In terms of drilling fluid mechanics, the problem
such as “the helical flow law of drilling fluid in eccentric annulus”, “cuttings
carrying law and capacity of drilling fluid in horizontal wells” etc. were
studied. The calculation formulas of viscosity function, velocity function,
flow rate and pressure of eccentric annulus helical flow were provided. In the
study of solid-liquid two-phase flow in horizontal well, cuttings bed three layer migration model and the
evaluation parameters and indexes of cuttings carrying capacity of drilling
fluid were put forward for the first time.
In terms of oil well cement chemistry
research, it mainly focuses on the hydration and hardening mechanism and law, corrosion
mechanism of oil well cement in the deep wells with high temperature and
corrosive complex environment. A method for the analysis of the composition and
microstructure of the hardening cement by X-ray diffract meter and SEM was
provided. The hot and difficult problems in oilfield production such as high
temperature resistant cement slurry system, cement slurry system of heavy oil
steam recovery well and corrosion resistant cement system design were studied.
