In this essay, gas hydrate formation conditions in pipeline, ۳۱۳ located at MIS field to joined point were simulated to database, by Olga Software, and at least it was realized that in pipeline ۳۱۳, to joined point, the condition is efficient for hydrate formation. To prevent hydrate formation in pipeline ۳۱۳ , methanol ۰.۱% mole applied and studied as inhibitor and insulator to control the temperature in the pipeline and it was observed that methanol injection causes hydrate formation to be declined and consequently hydrate formation pressure to be increased in the pipeline.
