| 摘 要： | 本文根据岩石孔隙中的天然气引起介电测井孔隙度减小和密度测井孔隙度增大的原理,建立了双密度重叠找气新方法,消除了岩性的影响,提高了测井找气的分辨率,增加了评价气层的直观性。该方法用于寻找陕甘宁盆地低孔隙白云岩气藏,获得了明显的地质效果。这种方法还可以在其它储层岩性气藏中应用。

| Abstract: | Based on the principle that natural gases in pores of rocks cause the redaction of porosity in dielectric log and growth of porosity in density log, tnts paper has brought forward a new dcal density superimposition gas-search method, which can get rid of the influence of thelithologic character and raise the resolution power in logging gas-search work and the degree of audiovisualization in the evaluation of the gas layer. When used in the search for gas reservoirs in lowporosity dolomite of the Shaaoxi-Gansu -Ningxia basin, this method yielded obvions geological effe ets. It can also be used in search for gas reservoirs in other rocks that bort natural gases. |
