单家寺区块油藏为稠油油藏,利用水平井开发特超稠油油藏具有吸汽能力强、注汽质量高,产液能力强,热损失小、周期油汽比高的特点,最终提高油藏最终采收率。根据所钻井的施工难点,形成了一套钻井施工方案,为后续该区块安全施工提供了一定技术保障,为稠油油藏水平井施工提供依据。 The reservoir of Shanjiashan block is a heavy oil reservoir. The development of extra-heavy oil reservoirs with horizontal wells has the characteristics of strong suction capacity, high steam injection quality, strong liquid production capacity, small heat loss and high period oil-steam ratio , Eventually increasing the ultimate recovery of the reservoir. According to the construction difficulty of drilling, a set of drilling construction scheme has been formed, which has provided some technical support for subsequent safety construction of the block and provided the basis for horizontal well construction in heavy oil reservoirs.
