Abstract:Tight sandstone reservoirs are currently the focus and difficulty of unconventional oil and gas exploration and development. The effective description of the “sweet spot” of tight sandstone affects exploration and development strategies and well placement deployment. Tight sandstone reservoirs have tight lithology, rapid lateral changes and thin thickness. It is difficult to identify tight sandstone reservoirs and effective reservoirs only by P-wave impedance. In view of the above characteristics, based on petrophysical analysis, comprehensively restrict sparse pulse inversion and geostatistical inversion for reservoir prediction, AVO fluid detection technology and P/S wave velocity ratio (Vp/Vs) was used to describe effective reservoirs Distribution range. Research on tight sandstone reservoir identification and gas-bearing prediction methods was carried out, which improved effective reservoir identification and prediction accuracy, and applied it in the well location deployment of Taiyuan Formation in Block F of the Ordos Basin, achieving good practical results and having promotion value and operability.
