【摘要】：鲁克沁油田是1996年在吐哈盆地吐鲁番拗陷台南凹陷北部鲁克沁构造带发现的超深稠油油田,油田类型为断块型边底水稠油油藏。由于油层埋藏深(-2300m~-3700m),原油粘度大(50℃地面原油粘度可达9569~25570mPa.s,地层原油粘度为154-526mPa.s),储层胶结疏松油井出砂,其开发工艺技术没有成熟经验可借鉴。在开发中,如何将稠油从井底举升到地面是摆在开发技术人员面前的一大难题。从1997年开始,先后开展了环空注入稀油有杆泵采油、水力活塞泵采油、喷射泵采油、电热杆过泵加热抽稠泵采油、空心杆掺稀油有杆泵采油等试验,最终只有电热杆过泵加热抽稠泵采油和空心杆掺稀油有杆泵采油成功将稠油举升到地面,可实现油井连续生产。通过经济评价,空心杆有杆泵泵上掺稀油采稠油是一种较为经济有效的举升方式。因此作为一项成熟技术在油田得以推广应用,从此,拉开了鲁克沁油田产能建设的序幕。
