Abstract

Abstract:

The types of reservoir spaces of the Ordovician carbonate reservoir of theblock-4 of Tahe oilfield in Tarim Basin are dominated by cavern solution pore and vug,and fracture systems formed by karstification and tectonic movement.The caverns are discrete and the main reservoir spaces,while the fractures are the major migration pathways.The typical characteristics of the carbonate reservoir in the study area are of large burial depth,strong heterogeneity and large difficulty in petroleum production and so on.This paper analyzes the interference features of production performance of 7 wells in S48 unit of block-4 in Tahe oilfield.Four types of reservoir spaces are recognized based on analysis of static datum,including cavern-,fracture-,fracture-vug- and tight-types.Based on the analysis,four types of inter-well communication model are proposed,including inter-well ca-vern communication,inter-well fracture communication inter-well fracture and vug communication and inter-well non-communication.Finally,the interference well test theory and tracer diffusion theory are used to analyze the flow coefficient and quantify inter-well connectivity.It is pointed out that inter-well communication models and connectivity should be integrated into the prediction and production of residual oil in fractured-vuggy carbonate reservoir.

Key words: connectivity, communication model, dynamic disturbance, reservoir space, fractured-vuggy reservoir, carbonate reservoir, Tahe oilfield
