纯梁采油厂的疏松砂岩油藏自投入开发以来先后采用了多种防砂治理的工艺技术,但由于油层出砂严重,粘土含量高、油稠,受防砂精度、粘土(胶质)堵塞等油藏物性、采油工具及开采技术等诸多因素限制,导致防砂效果差、防砂周期短、对产量影响大等不利因素,导致长时间一直未能投入有效开发。近年来经过不断探索,重点开发、引进适应性强、针对性高、增产增效防砂新技术,以及配套完善蒸汽吞吐开采工艺技术,使得该油区进入高效开采阶段。
The pure sandstone reservoir of the pure beam production plant has adopted many kinds of sand control technologies since it was put into development. However, due to the serious sand production, the clay content is high, the oil content is thick, the precision is controlled by the sand, the clogging of the clay Possession of property, oil recovery tools and mining technology and many other factors, resulting in poor sand control, sand control cycle is short, the impact of yield and other unfavorable factors, resulting in a long time has not been put into effective development. In recent years, through continuous exploration, focusing on the development and introduction of adaptable, highly targeted, stimulation of sand production and efficiency of new technologies, as well as complete steam huff and puff mining technology, making the oil into the efficient mining stage.
