Comprehensive classification and development strategies of Ordovician carbonate condensate gas reservoirs in Tazhong M area
摘要
Abstract
The multi-stage Ordovician carbonate condensate gas reservoir in Tazhong M area has the characteristics of multi-type of reservoir spaces,multi-phase fluids and multi-type of water,which brings great difficulty to development.The characteristics of reservoirs,fluid,natural energy and water drive of 14 Ordovician carbonate condensate gas reservoirs were analyzed and evaluated comprehensively.Three types of reservoir spaces,three types of fluids,three types of natural energy and three types of water drive were classified,which respectively include"caves type,fracture-vug type,vug type","reservoir with oil rim,mid-high condensate oil without oil rim,low(minor)condensate oil without oil rim","sufficient natural energy,less sufficient natural energy,insufficient natural energy "and "rigid water drive,elastic strong water drive,elastic medium water drive".On this basis,twelve combination types were classified comprehensively.Based on the comprehensive classification results,well location and well pattern optimization,rational utilization of natural energy,pressure maintaining by water injection and gas injection and other strategies were proposed to achieve good results.关键词
