机采井泵下防砂沉砂装置
摘要：
本发明实施例提供一种机采井泵下防砂沉砂装置。该机采井泵下防砂沉砂装置包括：坐封在套管内的丢手封隔器、双管悬挂总成、防砂管、打孔管和沉砂管，其中所述双管悬挂总成一端与所述丢手封隔器连接，另一端包括内悬挂接头和外悬挂接头；所述防砂管一端与所述内悬挂接头连接，另一端与所述沉砂管连接；所述打孔管与所述外悬挂接头连接；所述沉砂管一端与所述防砂管连接，另一端封闭。这样该装置可以阻隔井下原油直接通入油泵，并将原油中的砂粒过滤出来并落入装置底部。从而起到了防砂和沉砂的作用。
摘要（英）：

The invention relates to an embodiment of a machine oil well pump sand control and sand settling device; the machine oil well pump sand control and sand settling device comprises a release packer, a dual-pipe suspension assembly, a sand control pipe, a punching pipe and a sand settling pipe; one end of the dual-pipe suspension assembly is connected with the release packer, and the other end comprises an inner suspension joint and an outer suspension joint; one end of the sand control pipe is connected with the inner suspension joint, and the other end is connected with the sand settling pipe; the punching pipe is connected with the outer suspension joint; one end of the sand settling pipe is connected with the sand control pipe, and the other end is closed; the machine oil well pump sand control and sand settling device can prevent underground crude oil from directly entering the oil pump, and sand grains in the crude oil can be filtered and fall into the bottom of the device, thus providing sand control and sand settling effect.
