摘　　要：塘沽油田油层埋深2500~4411.4 m,原油密度0.8030~0.9592 g/cm3,凝固点13~59℃。在以往的开采过程中,由于构造破碎、断块小、天然能量不足、油层埋藏深、储层物性差、原油性质差、井眼轨迹变化大、地面环境复杂等特点,油井不能正常生产。针对塘沽油田开采中出现的问题,通过综合利用小泵深抽、深穿透射孔、压裂改造等先进适用的工艺,使油井得以正常高效生产。the oil layer of Tanggu Oilfield buried in the depth of 2500-4411.4 meters,the density of the crude oil is 0.8030～0.9592 g/cm^3,its solidifying point is 13～59 ℃.In the history of its performance,since its crush structure,little block,deficiency of natural energy,deeper depth of oil layer,bad physical property of the reservoir,bad character of crude oil,greater alteration of well track and complicated surface environment,oil well can not normally performance.In view of the problem in the oil exploitation of Tanggu Oilfield,by means of comprehensively using little pump deeper pumping,deeper breakthrough blasting and fracturing,advanced the efficiency of oil field.
