摘要
本文在对苏里格地区苏X井区石盒子组盒8段沉积相特征研究的基础之上，利用石盒子组盒84段GR、SP测井曲线特征，将研究区最发育的河道和心滩沉积储层分为箱形和钟形砂体两类，在此基础之上，分别作出了箱形和钟形砂体的声波时差一电阻率、密度一电阻率交会图，确定了研究区箱形和钟形砂体的气层、含气层、水层以及干层的界限值，并进一步的对建立的解释图版参数进行了应用效果分析。
On the basis of analysis of the sedimentary facies in He 8 interval, Shihezhi group, Su X well field, Sulige area, GR and SP well logs are used in He 8 interval.The most developed riverway and channel bar deposit reservoirs in the study area are divided into two types: box-shape sand body and bell-shape sand body.The acoustic differential time - resistivity and density - resistivity cross-plots are made for each. The threshold value for gas zone, gas-bearing zon, water zone and dry zone of these two types in this area are determined. The application effect is analysed through the parameters established by the interpretation chart.
