摘要
安塞油田浅层主要位于安塞东,占老区近1/3面积,油层埋深浅,一般不超过1000m,含油层系多、出油井点多,资源潜力巨大,采用常规方式开发,单井产量低,经济效益差。经过探索与实践,2011年通过超前注水、水平井开发、"子母井场"技术,已初步形成了浅油层开发新模式,为后期有效动用浅层资源提供了一定借鉴。同时,针对浅层开发仍然有一系列技术难题今后一段时间内必须要解决,并提出了下步的攻关方向。
Middle and shallow strata of Ansai oilfield is located in the east, accounting for one third of old area, reservoir buried depth is shallow, generally no more than 1 000 m, oil-bearing layers are enough, resource potential is huge. But using the conventional development way, single well production is low, economic benefit is poor. Through exploration and practice, advanced water injection and horizontal well development were carried out in 2011, a new model of developing shallow oil reservoir was established, which could provide a certain reference for late effective production of shallow resources. At the same time, in view of a series of technical problems in the shallow development, they must be solved, and the next research direction was proposed.
