塔里木油田具有埋藏深、高温高压、油藏类型多、原油物性变化大、气油比差异大、地层水矿化度高等特点,给采油工艺技术配套带来很大困难。为此,塔里木油田完井方式可分为两大类:射孔完井和裸眼完井。机械采油应用电潜泵、气举、有杆泵为主的配套工艺技术。介绍了适合于本地区的增注技术、堵水技术、水平井开采技术和凝析油开采工艺技术,指出了塔里木油田亟待完善、发展的采油工艺技术。

With the characteristics of deep burial depth, high temperature and pressure, various types of reservoir, great change in oil property and gas/oil ratio, as well as high salinity of formation water, it is very difficult to match the oil producing technologies in Tarim Field. Therefore, there are two main types of com pletion methods in the field, and matched technologies of electric submersible pump, gas lift and sucker rod pump are adopted. This paper introduces the suitable well stimulation, water plug technology, horizontal well production technology and gas condensate production technology. In addition, this paper further points out the oil producing technologies waited to be improved and developed in the field.
