【摘要】：蘇里格氣田開發(fā)已全面進(jìn)入穩(wěn)產(chǎn)階段,后備優(yōu)質(zhì)儲(chǔ)量資源相對(duì)不足,對(duì)低于物性下限標(biāo)準(zhǔn)的儲(chǔ)層進(jìn)行潛力儲(chǔ)層篩選并評(píng)價(jià)其開發(fā)可動(dòng)用性,具有重要意義。面對(duì)氣田致密砂巖儲(chǔ)層分類不盡完善的問題,繼承性開評(píng)展了儲(chǔ)層系統(tǒng)性綜合評(píng)價(jià),將儲(chǔ)層劃分成5大類6種類型,并明確Ⅲ2類儲(chǔ)層是未來最具有開發(fā)潛力的儲(chǔ)層類型。潛力儲(chǔ)層形成主控于同砂巖粒度密切相關(guān)的儲(chǔ)層物性,即發(fā)育于高能心灘-辮狀河道微相中上部、中-低能心灘-辮狀河道微相主體及中下部物性較差的中-細(xì)粒巖相部分�？偨Y(jié)了潛力儲(chǔ)層的6種發(fā)育模式,提出了間接動(dòng)用、組合動(dòng)用和直接動(dòng)用等3種開發(fā)動(dòng)用方式�？蓜�(dòng)用性評(píng)價(jià)表明,直接和間接動(dòng)用方式開發(fā)效果相對(duì)較好,潛力儲(chǔ)層具備較好的開發(fā)前景。潛力儲(chǔ)層特征及可動(dòng)用性評(píng)價(jià)可為未來此類儲(chǔ)層開發(fā)提供有力支撐。
[Abstract]:The development of Sulige gas field has entered the stage of stable production, and the reserve quality reserves are relatively insufficient. The reservoir below the lower limit of physical properties is screened for potential reservoirs and its development availability is evaluated. Facing the problem that the classification of tight sandstone reservoir in gas field is not perfect, the inheritance evaluation develops the comprehensive evaluation of reservoir system and divides the reservoir into 5 categories and 6 types. It is also clear that type 鈪，
