Development of semiconsolidated collectors always becomes complicated by both sand production and contamination, and decision arise at that problem become paramount task for hydrocarbons production. These complications are typical for Gatchina underground gas stor-age. The produce reservoir represents unconsolidated sandstone, that’s why the facility works in the conditions of overabrasion. Sand production is rather considerable.
Fight with scale in the well operation is one of the most important ways to increase the efficiency of oil production. Scale formation in the bottom hole reservoir and downhole equipment reduce their productivity, leading to the current unplanned and costly workovers. The piper describes the characteristics of the process of scaling in wells in the later stages of the development of oil fields.
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».
