曙一区杜84块是辽河油田超稠油难采储量中规模较大的具有代表性的区块, 开
发中存在注汽困难、生产周期短、油井作业频繁热损失大、地层普遍出砂、综合成本高、开采难
度大等一系列问题。根据油藏生产动态和综合分析油藏地质参数, 结合油藏特征及原井网开
发状况, 通过对杜84- 平28井优化设计和精心组织施工, 重点对施工中产生的主要问题进行
分析, 采取科学合理的技术措施, 取得显著的开发效果。
B lock Du 84 o f Shu 1 d istrict, L iaohe O ilfie ld, is a
represen tational b lock, wh ich has the hard- produc ing ex tra
- heavy o il reserves w ith a larger size in L iaohe Oilfie ld.
There are lots o f d ifficu lties dur ing exp lo ita tion, such as gas
injection difficu lty, short production cycle, greater heat loss
because of continua l we ll operating, un iv ersal sand
production in the form ation, high ove ra ll cost, exploita tion
d ifficu lty and so on. Based on the reservo ir production
perform ance and com prehensive g eo log ic analysis o f reservo ir
param eters comb ined w ith the reservo ir features and the
pr im ary w ell ne tw ork exp lo itation sta te, this paper ma in ly
analyses some problem s presented during operation. By
m eans of optim izing design and careful organ izing and
operating on W ell Du 84 - P ing 28, and adopting sc ientific
and ra tiona lm easures, w e have obta ined obvious exploita tion
effects and have prov ided va lued resea rch clews and practica l
