摘　　要：查48区块葡萄花油层经历了复杂的沉积和成岩作用,具备低孔低渗特点。利用测井、录井、岩心和试油等资料,分析了该区储层的岩性、物性、含油性和电性特征及其相互关系,并确定出了该区有效厚度下限标准:孔隙度为10.2%,渗透率为0.14 mD;电性下限电阻率为5.5Ω·m,声波时差为250μs/m,含水饱和度小于63%。从而为查48区块进一步储层评价和增产,提供了有力的依据。Putaohua formation in Cha 48 block experienced complex deposition and diagenesis, has low porosity and permeability, By using well logging,logging,core and well testing data of Cha 48 block, the lithology, physical properties, oil-bearing and electrical characteristics and their relationship of the reservoir were analyzed, and the floor standards of effective thickness of the region were determined as follows： porosity 10.2% ,permeanbiliy 0.14×10-3μm2,and the lower limit of electrical property 5.5Ω·m,the acoustic time 250μs/m and water saturation less than 63%.
