Summary
Petroleum engineering involves the simulation of various complex flow and transport problems in underground reservoirs, including exploring the flow mechanism of oil, gas and water in the formation through physical simulation, and using computational methods to realize efficient and high-precision calculation of multiphase flow, non-isothermal flow, compositional model and fluid-solid coupling problem in conventional or unconventional oil and gas reservoirs. In addition to the flow problems in the underground reservoir, the well drilling process involves the simulation of mass and heat transfer of drilling fluid in the wellbore annulus, and the complex flow simulation of lifted multiphase fluid in the wellbore during production or injection, and the coupling simulation of the above various flow and transport problems. Therefore, this special issue covers a wide range of topics, including but not limited to:
(1) Numerical simulation of heat and mass transfer in reservoir;
(2) Numerical simulation of shale gas flow in tight shale reservoir;
(3) Experimental study about the flow mechanisms of underground fluid;
(4) New numerical simulation technology in reservoir simulation;
(5) Coupling simulation of heat and mass transfer in wellbore annulus during well drilling;
(6) Simulation of flow and transport in fractured reservoirs;
(7) Coupling study of flow and geomechanics;
(8) Simulation of Multiphase flow in wellbore.

Abstract Due to the characteristics of reservoir formation, the producing level of low permeability reservoir is relatively very low. It is hard to obtain high recovery through conventional development schemes. Considering the tight matrix, complex fracture system, low production level of producers, and low recovery factor of M block in Xinjiang oilfield, it is selected for on-site pilot test of nitrogen foam flooding. Detailed flooding scheme is made and the test results are evaluated respectively both for producers and injectors. The pressure index, filling degree, and fluid injection profile are found to be all improved in injectors after injection of nitrogen… More >

Abstract In gas storage or high-pressure gas wells, annular pressure is an unavoidable threat to safe, long-term resource
production. The more complex situation, however, is multiple annular pressure, which means annular pressure
happens in not only one annulus but two or more. Such a situation brings serious challenges to the identification of
well integrity. However, few researches analyze the phenomenon of multiple annular pressure. Therefore, this paper
studies the mechanism of multi-annular pressure to provide a foundation for its prevention and diagnosis. Firstly,
the multi-annular pressure is classified according to the mechanism and field data. Then the failure mechanism and
function…

Abstract The reservoir is the networked rock skeleton of an oil and gas trap, as well as the generic term for the
fluid contained within pore fractures and karst caves. Heterogeneity and a complex internal pore structure
characterize the reservoir rock. By introducing the fractal permeability formula, this paper establishes a
fractal mathematical model of oil-water two-phase flow in an oil reservoir with heterogeneity characteristics and numerically solves the mathematical model using the weighted least squares meshless method.
Additionally, the method’s correctness is verified by comparison to the exact solution. The numerical results
demonstrate that the fractal oil-water two-phase flow mathematical…
