【摘要】:魯克沁油田是1996年在吐哈盆地吐魯番拗陷臺南凹陷北部魯克沁構造帶發(fā)現(xiàn)的超深稠油油田,油田類型為斷塊型邊底水稠油油藏。由于油層埋藏深(-2300m~-3700m),原油粘度大(50℃地面原油粘度可達9569~25570mPa.s,地層原油粘度為154-526mPa.s),儲層膠結疏松油井出砂,其開發(fā)工藝技術沒有成熟經(jīng)驗可借鑒。在開發(fā)中,如何將稠油從井底舉升到地面是擺在開發(fā)技術人員面前的一大難題。從1997年開始,先后開展了環(huán)空注入稀油有桿泵采油、水力活塞泵采油、噴射泵采油、電熱桿過泵加熱抽稠泵采油、空心桿摻稀油有桿泵采油等試驗,最終只有電熱桿過泵加熱抽稠泵采油和空心桿摻稀油有桿泵采油成功將稠油舉升到地面,可實現(xiàn)油井連續(xù)生產。通過經(jīng)濟評價,空心桿有桿泵泵上摻稀油采稠油是一種較為經(jīng)濟有效的舉升方式。因此作為一項成熟技術在油田得以推廣應用,從此,拉開了魯克沁油田產能建設的序幕。
