There is full rationale of the phenomenological model of complicated riphean fractured carbonate reservoirs of Yurubcheno-Tokhomskaya oil-gas bearing area, created for simulation of development process for unique oil and gas deposits. The block discrete organization of these complex structure reservoirs are allow them non-additive and non-linear properties under development. Their marked similarity of their structure in a wide range of sizes, as well as the phenomenon of self-organization characteristic of complex nonequilibrium systems. Based on these production rates and their total cumulative production within such hydrocarbon obey a power law distribution, which is characteristic of the behavior of many nonlinear systems and can be described by Pareto. To implement the suggested model has been written special computer program compatible with the hydrodynamic simulation «Tempest MORE» of «Roxar».
It is determined that main reasons of permeability reservoirs decrease in Nizhnechutinskoe oil field are capillary pressures and elastic stresses, appearing at depression making. It is displayed that to reduce tangential stresses in oil bearing reservoirs it is expedient to make vertical slits in oilwells’ open holes.
The peculiarities of elastic stresses in open hole wells’ of Gatchina gas storage reservoir are researched. It is revealed that in depression more than 1,5 MPa gas bearing rocks start to destroy. On the basis of studying of correlation relation between technological parameters of gas wells’ production and evacuation of sand the equations of plural regression are constructed. These equations are used to make prediction of sand evacuation at each producing gas well.
