针对稠油疏松地层出砂这个问题，各油田都在想方设法来提高防砂效果，防砂是这类油藏正常生产的一种必要手段。现探讨携砂生产的可行性，不是要否定防砂，只想探索一条适合稠油出砂油藏生产的新思路。携砂生产不是主张出砂，它应用的前提条件是必须有效地保持地层中骨架砂拱的
In response to the problem of sand production in loosely packed heavy oil fields, all the fields are trying their best to improve the sand control effect. Sand control is a necessary measure for the normal production of such reservoirs. We are now discussing the feasibility of carrying sand production, not to deny sand control, just to explore a new method for the production of heavy oil sands reservoir. Carrying sand production is not advocated for sand, it is the prerequisite for the application must be effective to maintain the framework of the sand arch arch
