塔河油田×区奥陶系油藏埋藏深、温度高,原油具有高粘、高含腐蚀介质的特点,针对×区奥陶系油藏的特点对该区的采油工艺主要是稠油降粘工艺技术、防腐工艺技术、大管径采油工艺技术和电泵深抽采油工艺技术进行了研究与应用,对高温深井的酸压工艺技术也进行了研究与应用,解决了×区超绸油开采的难题,为以后类似油藏的开发提供了宝贵的经验,F1、F2等井成功进行正掺反采大管径采油为超稠油的开采创新了思路。
The Ordovician reservoir in the × district of Tahe Oilfield has the characteristics of deep burial, high temperature and high viscosity and high corrosive medium. According to the characteristics of Ordovician reservoir in area ×, the oil recovery process in this area is mainly that of heavy oil Technology, anti-corrosion technology, large-diameter oil production technology and electric pump deep-pumping oil technology research and application of high-temperature deep well acid pressure process technology has also been studied and applied to solve the × District of the ultra-silk oil production Which provided valuable experience for the development of similar reservoirs in the future. The success of wells such as F1, F2 and so on, which successfully exploit the large ore size of positive doping and reverse mining, has created a new thinking for the exploitation of extra-heavy oil.
