基于恒速压汞技术的低渗储层孔隙结构与渗流能力——以珠江口盆地文昌A凹陷珠海组为例
PORE STRUCTURE AND PERMEABILITY OF LOW PERMEABILITY RESERVOIR BASED ON CONSTANT SPEED MERCURY INJECTION TECHNOLOGY:TAKING ZHUHAI FORMATION IN WENCHANG A SAG OF ZHUJIANGKOU BASIN AS AN EXAMPLE
摘要
Abstract
Characteristics of pore structures and development difficulties of the low-permeability gas reservoirs in the Zhuhai Formation in Wenchang A Sag of the Zhujiangkou Basin were studied with the method of constant speed mercury injection.Results show that:① pore radius are similar for the cores with different permeability,throat is the main factor determining the reservoir permeability in the study area.The mainstream throat radius is the key physical parameter to be used to evaluate per colation ability and development difficulty of a low permeability reservoir;②1 × 10-3μm2 is is a critical value for a low permeability gas reservoir.While the permeability of gas reservoir is higher than 1 × 10-3μm2,the development difficulty of Zhuhai Formation in Wenchang ASag is getting smaller;and while the permeability of super-low permeability reservoirs near is lower than 0.1 × 10 3 μm2,the development difficulty of Zhuhai Formation in Wenchang A Sag (ZH3 of Wenchang WC-Y1 well) is greater.关键词
