随着胜利油田开发的不断深入,以滨南、盐家、富台、大王北等近20个油气区块为代表的古潜山、砂砾岩类型的深层低渗油藏(累计上报探明储量近3亿t,占总动用储量的17.3%),成为采油厂上产的主力阵地。该类油藏具有储层埋藏深(3 500m以上)、动液面低(2 000m以上)、产液量高(>20m3/d)等特点。针对此类油藏采用有杆泵助力深抽技术,可在不增加抽油机悬点载荷条件下,进一步加深泵挂,放大生产压差,提高油井产量,从而达到降本增效的目的。该技术主要由助力深抽装置、脱接器及
With the deepening development of Shengli Oilfield, deep-seated low-permeability reservoirs of ancient buried hill and conglomerate type, represented by nearly 20 oil and gas blocks such as Binnan, Yanjia, Futai and Dawangbei, Nearly 300 million tons, accounting for 17.3% of the total utilization of reserves), become the main production base of the oil production plant. Such reservoirs are characterized by deep buried reservoirs (more than 3 500m), low dynamic fluid surface (over 2,000m) and high fluid production (> 20m3 / d). For such reservoirs using rod pump power deep pumping technology, can not increase the pumping unit hanging point load conditions, further deepen the pump hanging, enlarge production pressure, improve oil production, so as to achieve the purpose of reducing cost and increasing efficiency. The technology is mainly assisted by deep pumping devices, connectors and
