Application of Numerical Simulation Technique in Early Development of Carbonate Reservoir- an example from Ordovician reservoir in District No.3 of Tahe oilfield

Abstract

Abstract: The Ordovician reservoir in Tahe oilfield is characterized by extremely strong heterogeneity with enormous thickness of solution fissure-cavity reservoir rocks, during its development, most wells appear quick water breakthrough, quickly raising water-cut and quick production decline. This paper studied the geologic factors, recovery mechanisms and water coning of Ordovician reservoir in District No.3 by means of numerical simulation technique, put forward the principle of small oil well perforated extent,contolling recovery rate during production and early water or gas injection for supplementary energy. These provide foundation for reference for promoting high effective development of Ordovician reservoir in District No.3, Tahe oilfield.

Key words: Carbonate reservoir, solution fracture, vug, reservoir, numerical simulation, development mechanism, Tarim basin, Tahe oilfield
