Abstract:

Chinese oil companies have more and more low-degree exploration oversea basins or blocks,there's a keen need for some techniques which can get the exploration targets quickly in such area.On the basis of intimate relationship between play and exploration deployment,the paper discussed the definition of play,the difference between play and zone,and the content of play analysis.More attention was paid on the application of the play quick analysis technique in Melut Basin with low-degree exploration.The domestic exploration procedure usually divided a basin into planar areas in the first stage,then evaluated the layers of each area individually in the second stage.Under the condition of good seismic resolution,the exploration of Melut Basin abandoned the traditional model.In the first exploration stage,several plays were divided vertically in order to show the characteristics of petroleum accumulation more clearly.With the assurance of source rock,the main play and prospect targets were chosen quickly by the assessment of reservoir,cap rock,migration passageway,seal ability of the faults,structure characteristics,favorite traps and the allied conditions.Good exploration result has been obtained in Melut Basin.

Key words: play, quick analysis technique, low-degree exploration basin, Melut Basin, exploration target
