The invention belongs to the technical field of petroleum and natural gas exploration and development, and provides a method and a device for analyzing the rock resistivity of glauconite sandstone. Generating a first relation curve and a second relation curve according to the different glauconite content conditions, the rock water saturation of the glauconite sandstone, the rock resistivity of the glauconite sandstone and the rock resistance increase rate of the glauconite sandstone corresponding to the different glauconite content conditions; and analyzing the change trend and the change degree of the rock resistivity and the rock resistance increase rate of the glauconite sandstone to obtain an analysis result. According to the analysis method provided by the embodiment of the invention, quantitative analysis can be carried out on the low-resistivity cause of the glauconite sandstone stratum, and the influence and degree of the change of the content of glauconite, the change of the rock resistivity of the glauconite sandstone and the change of the rock resistance increasing rate can be quantitatively judged.

The invention belongs to the field of petroleum and natural gas geological exploration, and provides a glauconite sandstone reservoir evaluation method which comprises the following steps: determining main control factors influencing reservoir physical properties; counting the actually measured content of the main control factors; establishing a semi-quantitative relationship between the actually measured content of each main control factor and reservoir physical properties, and determining a reservoir classification standard; establishing a logging prediction model of the content of each main control factor; and predicting the content of the main control factors by using the logging prediction model, and evaluating and classifying the glauconite sandstone reservoir by using a reservoir classification standard. The method can provide method support for optimization of the glauconite sandstone reservoir under the background of the land shed, and improves the trap risk evaluation precision and the trap drilling success rate, thereby reducing the oil and gas exploitation discovery cost.
