1、XXXX大學(xué)本科生畢業(yè)設(shè)計（論文）摘要海塔盆地蘇德爾特油田自下而上發(fā)育兩套油層，下部為裂縫性古潛山油層，上部為含凝灰質(zhì)強水敏特-超低滲透砂礫巖油層。布達(dá)特裂縫性潛山油層與國內(nèi)外其它潛山油層相比，具有裂縫發(fā)育程度差、連通狀況差的特點，油井投產(chǎn)后成片出現(xiàn)低效井；興安嶺油層由于凝灰質(zhì)含量高、儲層物性差，注水井投注后吸水狀況差，部分區(qū)塊注不進(jìn)、采不出。單井平均日產(chǎn)量在0.5t以下的低效井占到全油田的40%。因此低效井的治理是油田開發(fā)的重要內(nèi)容。本文通過裂縫性潛山油藏有效儲層識別方法研究、含凝灰砂礫巖油藏
2、有效厚度電性標(biāo)準(zhǔn)制定方法研究、低效井成因分類方法研究，初步搞清了布達(dá)特油層有效儲層識別方法以及貝16區(qū)塊興安嶺油層Ⅰ、Ⅱ油組有效厚度電性標(biāo)準(zhǔn)制定方法，基本搞清了低效井的成因及其相適宜的治理對策，在現(xiàn)場試驗中取得了較好的應(yīng)用效果。關(guān)鍵詞：蘇德爾特；古潛山；凝灰質(zhì)；低效井XXXX大學(xué)本科生畢業(yè)設(shè)計（論文）AbstractTwosetsofbottom-updevelopmentinsideSuderteoilfield，thelowerpartisin-fracturedburiedhilloill
