The exploration in recent years has proved that Heidimiao reservoir in southern Putaohua structure has a good exploration prospect. The research on sand bodies in Heidimiao reservoir is few. The facies change in terrestrial formation is fast, which causes great lateral variation of sand bodies, so it is difficult to carry out fine contrast between sand bodies. TakingMao 701 block in Aonan Oilfield as a research example, based on the sandstone classification, fine sand body contrast ofHeidimiao reservoir is carried out by constrained seismic inversion. The result of seismic inversion and drilling practice result show that the first part of Heidimiao reservoir vertically developed well, there are many vertical sand body layers which superimpose with large gross thickness, and the sand bodies can be executed tracing contrast on the horizontal; while the sand body of the second part of Heidimiao reservoir is basically undeveloped. It is helpful to exactly predict the favorable accumulation zone and provide an important geological basis for instructing the oil and gas exploration ofHeidimiao reservoir in Aonan Oilfield.
