Under the condition of the borehole and sandstone formation filling with oil and water, respectively, the ability is different when different energy windows are selected to distinguish formation by simulating the detector response spectrum of various diameters and length of NaI and BGO crystal. The C/O value difference of BGO crystal is higher than that of NaI crystal when the energy window includes photoelectric peak, the first and the second escape peaks, but it is less affected by the different sizes of detector crystal. Using photoelectric peak corresponding to the energy window, the C/O value difference of BGO crystal detector is much larger than that of NaI, but it increases with the crystal size increasing. The C/O value is greatly affected by energy drifting, while relatively a little by energy resolution.

对于井眼和地层流体分别为油和水砂岩地层，模拟改变NaI和BGO晶体探测器的直径和长度时的非弹性散射γ射线响应能谱，采用不同能窗处理方法对地层流体的分辨能力不同，选取光电峰和第一、第二逃逸峰对应的能量窗时，BGO晶体探测器比NaI晶体探测器测量的C/O差值大，但受尺寸的影响不大；采用光电峰对应的能量窗时，BGO晶体探测器测量的C/O差值比NaI的大得多，且随尺寸的增加差值增大；能量道的漂移对C/O值影响较大，而能量分辨率对差值影响相对较小。

砂岩的孔隙率可能是20%或者更多，这就好比在一个像冰箱大小的一立方米岩石中，能够吸收200或者更多公升的水。

Based on the analysis of the mutual action between CO2 fluids and sandstone, it is found that the higher content of dawsonite is the main cause for poorer reservoir properties, and the dawsonite is formed later than other authigenic minerals and no erosion occurres after the pores filling, which are the basic factors resulting in poor reservoir properties.

分析CO2流体与砂岩的相互作用发现，片钠铝石含量较高是储层物性变差的直接原因，而片钠铝石生长时间晚于其它自生矿物且在充填孔隙后没有发生溶蚀是储层物性变差的根本原因。

The morphology, occurrence and components of dawsonite were described, and the paragenetic sequence of sandstone and origin of CO2 forming dawsonite were investigated by polarization microscope, scanning electron microscope, Xray diffraction and MAT251 stable isotope mass spectrometer.
