An oil well casing inlet deflector, a handle, a limiting plate and a rectangular tube, which is characterized in that the limiting plate diameter and the casing valve sealing ring in the same diameter, lateral upper limit plate is smaller than the diameter of the vertical welding gate has a handle, in the limit plate. The lower part of the casing is less than the inner diameter of the gate opening has a through hole, and the rectangular inner liquid through hole to the inlet pipe end level of welding, the corner down, the central angle of the liquid inlet tube to the end of the horizontal section into the annular space between tubing and casing of the appropriate diameter less than the vertical section of oil pipe spacing between the casing and the the annular space. The utility model solves the problem that an oil pumping well and an electric pump well can handle the production accidents and do not release oil outwards, thereby preventing the crude oil from losing, polluting the environment and burning out the electrical components and equipment of the electric well.
【技术实现步骤摘要】
【技术保护点】
１．一种油井套管进液变向器，由把手、限位板和直角进液管组成，其特征在于限位板直径与套管闸门的密封钢圈内径相同，在限位板外侧中上部小于套管闸门的内径处垂直焊有一个手柄，在限位板的中下部小于套管闸门的内径处开有一个通液孔，通液孔的内侧与直角进液管一端水平焊接，拐角向下，直角进液管的水平段末端以伸进油管与套管之间环形空间的中部为宜，垂直段的直径小于油管与套管之间环形空间的间距。
