Abstract

PY gas field is at shelf break turing zone, and the special depositional environment leads to complicated T50 sand forecasting. The common AVO theory is not applicable in PY gas field. AVO fluid inversion (AFI) is a quantitative technique on the basis of statistical petrophysics and AVO theory, making carbon hydrogen probability graph. The predication of T50 gas sand using AFI suggest that the AFI theory can estimate the hydro of bored well and certified well validly and accurately. It can be believed that the applications of AFI will guide the additional exploration and improve success rates of gas exploration.
