一种带有防砂压实砂体的圆台筒体状近井地带模拟装置
摘要：
本实用新型提供了一种带有防砂压实砂体的圆台筒体状近井地带剪切模拟装置。该装置包括由圆台筒体与设置在所述圆台筒体小口径端的圆柱筒体组成的圆台状筒体；所述圆台状筒体上设有密封盖A和密封盖B；所述密封盖A位于所述圆柱筒体端，所述密封盖B位于所述圆台筒体端，所述密封盖A和密封盖B上分别设有密封管线接头a和密封管线接头b；所述圆柱筒体内设有与之过盈配合的圆环柱体；所述圆环柱体的下表面与所述密封盖B之间设有胶结砂体，所述胶结砂体内设有与所述圆环柱体的内腔相连通的圆柱孔；所述圆柱孔中、所述圆环柱体的内腔中和所述圆环柱体的上表面和所述密封盖A之间均设有压实砂体。本实用新型提供的剪切模拟装置可以广泛应用于油田化学驱提高采收率工艺中。
摘要（英）：

The utility model provides a round table cylindrical shell shaped near wellbore zone shearing analogue device with sand prevention compacting sand bodies. The device comprises a round table-shaped cylindrical shell consisting of a round table cylindrical shell and a cylinder cylindrical shell arranged at a small-bore end of the round table cylindrical shell; wherein the round table-shaped cylindrical shell is provided with a seal cover A arranged at an end of the cylinder cylindrical shell and a seal cover B arranged at an end of the round table cylindrical shell, the seal cover A and the seal cover B are respectively provided with a seal pipeline joint a and a seal pipeline joint b; the cylinder cylindrical shell is provided with a circular ring cylinder which is in interference fit with the cylinder cylindrical shell therein; a cementation sand body is provided between a lower surface of the circular ring cylinder and the seal cover B, the cementation sand body is provided with a cylinder hole therein, wherein the cylinder hole is connected with an inner cavity of the circular ring cylinder; and the compacting sand bodies are arranged in the cylinder hole, in the inner cavity of the circular ring cylinder, and between an upper surface of the circular ring cylinder and the seal cover A. The shearing analogue device provided by the utility model can be widely applied in a oilfield chemical flooding recovery efficiency improving technology.
