Title: Geneses of Low Resistivity Gas Zone and Its Log Interpretation Technology in SU Gas Field
Abstract: Since the geneses of low resistivity gas zone with sandstones are complex in SU gas field, it is difficult to indentify the gas zone and water zone. Log, geology and gas testing data are used for analysing the geneses and characters of low resistivity gas zones. It is confirmed that main causes resulting in low resistivity gas zones are the low and flat geologic structures, heterogeneity of sandstone, microscopic texture of reservoir, high bound water saturation, mud invasion and water increment on the clay membranes. Based on the above analysis, some interpretation methods such as compressional wave slowness acoustic gas detection, NMR logging and array resistivity inversion, are bought up to indentify low resistivity gas zones which provides us visible geologic results and improves the interpretation accuracy.
