过去由于没有有效的抗砂携砂采油装置，治砂害的重点是在防砂方面，如化学固砂、机械防砂，限制油井出砂，甚至企图将随粘油携出的大量细粉砂也限制在地层内，追求最小粒度的滤砂装置，此举不能说是无效，但急剧增加了采油成本，缩短生产周期。频繁的作业，给油田的生产管理带 In the past, there was no effective anti-sand and sand-carrying oil recovery device. The key point of sand control was sand control, such as chemical sand fixation, mechanical sand control, oil well sand limitation, and even attempts to limit the amount of fine silt carried with the oil In the strata, the pursuit of the smallest particle size of the sand filter device, this move can not be said to be ineffective, but drastically increased oil recovery costs and shorten the production cycle. Frequent homework, to the oil production management zone
