Iz tog razloga u bušotini na dubini utiskivanja, na operativnom ventilu, nema dovoljnog dinamičkog pritiska za iznošenje nafte na površinu. Ovo posebno dolazi do izražaja kod bušotina sa povećanom proizvodnjom slojne vode. Iz tog razloga u radu je prikazana metodologija i urađen model za optimalnu raspodelu gasa koji se utiskuje u svaku bušotinu za rad gaslift sistema. Primenjena je metodologija raspodele gasa za utiskivanje preko takozvane kumulativne krive baziranoj na dinamičkima karakteristikama svake pojedinačne bušotine. SUMMARY DETERMINING THE OPTIMAL AMOUNT OF GAS THAT IS INJECTED FOR THE GASLIFT SYSTEM WORK The problem that arises in the work of wells in the oil field Gaslift Amal to individual wells do not always have the necessary amount of gas for injection. Therefore, in a borehole at a depth of injection, the operating valve, there is not enough dynamic pressure for the removal of oil on the surface. This is particularly evident in wells with increased production of formation water. For this reason, the paper presents the methodology and drafted model for optimal allocation of the amount of gas injected into each well in the work gaslift of the system. The methodology for the allocation of quantities of gas injection through the so-called cumulative curves based on the dynamic characteristics of each well.
