2、育生物礁灘儲層。長興組頂部普遍發(fā)育一套厚度不等的潮坪白云巖;飛仙關(guān)組一段底部發(fā)育一套泥灰?guī)r沉積,泥灰?guī)r沉積厚度與長興組潮坪白云巖厚度有密切關(guān)系,具有厚度薄、低波阻抗的特征。為了防止在儲層預(yù)測中將泥灰?guī)r作為儲層,系統(tǒng)分析了泥灰?guī)r的測井響應(yīng)和地震響應(yīng)特征;根據(jù)測井分析結(jié)果并考慮泥灰?guī)r沉積環(huán)境,提出基于多屬性的高分辨率非線性參數(shù)反演、地震波阻抗反演、交會圖技術(shù)、沉積相和地震相分析相結(jié)合來識別礁灘相儲層中泥灰?guī)r的思路。通過實(shí)際資料的分析與應(yīng)用,證實(shí)了該思路對識別具有儲層特征的泥灰?guī)r的有效性。關(guān)鍵詞:礁灘相儲層;泥灰?guī)r;多屬性反演;波阻抗反演;地震相分析中圖分
