普光气田属于低孔、低渗、非均质性比较强的裂缝———孔隙型碳酸盐岩油气藏，其具有溶蚀孔洞发育、局部裂缝发育、储层孔隙结构比较复杂的特点。储层孔隙结构复杂导致了储层分类难度大、精度低等难题，常规波阻抗反演的方法已不能满足实际生产开发需要。而随机地震反演充分考虑地质规律、地震和测井资料，具有比较高的描述能力和分辨能力，能够为储层描述提供更加丰富可靠的信息。在普光气田应用结果表明该方法有效地压制了地震反演的多解性，预测结果良好。
普光氣田屬于低孔、低滲、非均質性比較彊的裂縫———孔隙型碳痠鹽巖油氣藏，其具有溶蝕孔洞髮育、跼部裂縫髮育、儲層孔隙結構比較複雜的特點。儲層孔隙結構複雜導緻瞭儲層分類難度大、精度低等難題，常規波阻抗反縯的方法已不能滿足實際生產開髮需要。而隨機地震反縯充分攷慮地質規律、地震和測井資料，具有比較高的描述能力和分辨能力，能夠為儲層描述提供更加豐富可靠的信息。在普光氣田應用結果錶明該方法有效地壓製瞭地震反縯的多解性，預測結果良好。

Puguang gas field is belong to fractured-porous carbonate gas reservoir with low porosity, low permeability and strong heterogeneity, it has the characteristics of the solution cave development and the local fractures development with more complex reservoir structure. The complex pore structures of the reservoir have resulted in many problems on the reservoir classification which is difficult and low accuracy. The conventional wave impedance inversion technique can't meet the requirement of practical production. But the stochastic seismic inversion can provide more reliable information for reservoir description, which has take full account of geological law and the seismic and logging data, it gets higher description and distinguish ability. Results of the application in Pugang gas field show that the method is effective to suppress the uncertainty of seismic inversion, the prediction is good.
