摘　　要：提高胡尖山地区长9储层测井解释精度,通过对各类资料的收集、整理、校正、分析,进行储层"四性"关系研究。认为长9储层属低、特低孔隙度-特低渗透率储层;岩性以长石砂岩为主,成分和结构成熟度均中等。研究确定了储层有效储层下限标准:物性下限标准孔隙度为7.3%,渗透率为0.28×10-3μm2;电性下限声波时差为214.2μs/m。To improve the accuracy of well logging interpretation of Chang 9 reservoir in Hujianshan area, data about neu- tron - density and porosity - permeability of reservoir are analyzed. The result shows that Chang 9 reservoir has features of low or super - low porosity and ultra - low permeability. Most rocks here are arkosic sandstones with ingredient and structure of middle maturity. The lowest standard of an effective reservoir, according to the research , is 7.3% of porosity,0.28 x 10 -3 m2 of permeability and 214 us/m of acoustic interval transit - time.
