【摘要】:魯克沁油田是1996年在吐哈盆地吐魯番拗陷臺(tái)南凹陷北部魯克沁構(gòu)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(dá)9569~25570mPa.s,地層原油粘度為154-526mPa.s),儲(chǔ)層膠結(jié)疏松油井出砂,其開(kāi)發(fā)工藝技術(shù)沒(méi)有成熟經(jīng)驗(yàn)可借鑒。在開(kāi)發(fā)中,如何將稠油從井底舉升到地面是擺在開(kāi)發(fā)技術(shù)人員面前的一大難題。從1997年開(kāi)始,先后開(kāi)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(guò)泵加熱抽稠泵采油、空心桿摻稀油有桿泵采油等試驗(yàn),最終只有電熱桿過(guò)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(shí)現(xiàn)油井連續(xù)生產(chǎn)。通過(guò)經(jīng)濟(jì)評(píng)價(jià),空心桿有桿泵泵上摻稀油采稠油是一種較為經(jīng)濟(jì)有效的舉升方式。因此作為一項(xiàng)成熟技術(shù)在油田得以推廣應(yīng)用,從此,拉開(kāi)了魯克沁油田產(chǎn)能建設(shè)的序幕。
