| 摘 要： | ＣＸ地区沙二段储层为砂泥岩薄互层，埋深在２０００－２７００ｍ之间，且砂岩速率大于泥岩速度。过去一直认为；砂岩含油气后，速度降低，含油性好的储层在地震剖面上就表现为弱振幅特征。

| Abstract: | The reservoir Sa-2 in CX area is a thin sand-shale interbed with buried depth from 2000m to 2700m,and the sandstone velocities are larger than the shale velocities. The previous view was that when the sandstone contains oil,the velocity will reduce,and the well oil-bearing reservoir should show weak amplitude feature in the seismic section. However, many drilling results demonstate that high production wells (well oil-bearing reservoir )all correspond to strong relection amplitude.So,starting from the forward models,we research the petrophysical and sedimentary facies characteristics and the physical and geologic mechanism for producing particular seismic facies using the log and core testing data. The correct signs fot hydrocarbon detection are thus constructed,improving the success rate of drilling from 47. 6% previously to more than 96% now. |
