Technical And Economic Analysis Of Fracture Low Permeability Reservoir Development

Low permeability reservoirs, widely distributed in some oil fields or basin, Is an important resource base on China’s oil industry to increase reserves and production. Consider the importance of cracks to low permeability reservoirs, we focus on emphasis by the theoretical analysis, numerical simulation and economic evaluation. Based on double low permeability fractured media percolation theory, numerical simulation of reservoir were applied to analysis the different distribution patterns of cracks, fractures of different densities, different production situations can change the permeability characteristics, This paper includes the following sections:1) We studied the basic characteristics of fractured low permeability reservoirs, the main affecting factors of the low permeability oil reservoirs and the production decline equation with the pressure gradient based on reservoir geology.2)We researched the main factors affecting oil production cost components and production costs according to relevant regulations of oil production.3)We build a single-phase flow of oil dual media model with CMG based on the theory of advanced fluid mechanics and fluid mechanics higher.4)We evaluated the reservoir case by using of basic economic indicators economics combined reservoir simulation results.
