【摘要】：蘇里格氣田開發已全面進入穩產階段,后備優質儲量資源相對不足,對低于物性下限標準的儲層進行潛力儲層篩選并評價其開發可動用性,具有重要意義。面對氣田致密砂巖儲層分類不盡完善的問題,繼承性開評展了儲層系統性綜合評價,將儲層劃分成5大類6種類型,并明確Ⅲ2類儲層是未來最具有開發潛力的儲層類型。潛力儲層形成主控于同砂巖粒度密切相關的儲層物性,即發育于高能心灘-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-細粒巖相部分。總結了潛力儲層的6種發育模式,提出了間接動用、組合動用和直接動用等3種開發動用方式。可動用性評價表明,直接和間接動用方式開發效果相對較好,潛力儲層具備較好的開發前景。潛力儲層特征及可動用性評價可為未來此類儲層開發提供有力支撐。
[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，
