岔河集油藏是一个被断层复杂化的断块砂岩油藏，１９７６年投入开发，累计采油９８８．８×１０４ｔ，累计产水８８７．１×１０４ｍ３，地质储量采出程度２２．０３％，可采储量采出程度７０．５％，综合含水６０．２％。由于断层发育、构造破碎复杂，含油层系多且分布零散，?
The Chaheji reservoir is a fractured sandstone reservoir that has been complicated by fault. Since it was put into operation in 1976, the total oil recovery is 988.8 × 104t, with an accumulated water production of 887.1 × 104m3 and a geological reserves of 22.03% Recoverable reserves of 70.5% recovery level, integrated water 60.2%. Due to the fault development, the structure is fragmented and the oil-bearing strata are scattered and scattered.
