Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plunger pumps, in particular to a novel waste oil sludge profile control plunger pump. Background Art
[0002] Oil fields often use waste oil sludge as the main raw material to prepare profile control agents, which are called waste oil sludge profile control agents. The use of waste oil sludge profile control agents for oil layer profile control can not only achieve the purpose of increasing production, but also consume a large number of harmful substances generated during the production process of oil fields.
[0003] During the oily sludge profile control process, it is necessary to use a plunger pump to pressurize the oily sludge profile control agent to more than 10MPa and pump it into the well. When an ordinary plunger pump pressurizes the profile control agent, the plunger makes axial reciprocating motion. When the plunger strokes to the right, the profile control agent is sucked into the pump body through the inlet valve. When the plunger strokes to the left, the profile control agent in the pump body is pumped out through the discharge valve. Common plunger pumps generally use a spring and a sealing ball to form a one-way valve structure to achieve pumping operation. However, the oily sludge profile control agent often contains some fine hard solid particles, such as sand, metal powder, etc. Therefore, during long-term pumping, fixed particles are easily accumulated in the gap of the spring, gradually affecting the stroke of the spring, and eventually causing the spring to get stuck, making it impossible to perform normal pumping operations.
[0004] To this end, the utility model provides a novel waste oil sludge profile control plunger pump, which solves the above-mentioned problem by setting structures such as a first elastic mechanism and a second elastic mechanism. Utility Model Content

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] Embodiment 1:
[0022] See also Figure 1-2A novel oil sludge profile control plunger pump comprises a bottom plate 1, a mounting block 2 is fixed on one side of the top wall of the bottom plate 1, a liquid inlet chamber 3 and a liquid outlet chamber 4 are provided in the mounting block 2, a through hole is penetrated between the liquid inlet chamber 3 and the liquid outlet chamber 4, a liquid inlet port 5 connected to the liquid inlet chamber 3 and a liquid outlet port 6 connected to the liquid outlet chamber 4 are provided on the side wall of the mounting block 2, a sealing ball 8 is installed in both the liquid inlet chamber 3 and the liquid outlet chamber 4, a No. 1 elastic mechanism 9 is fixed on the side wall of the liquid inlet chamber 3, a No. 2 elastic mechanism 10 is fixed on the side wall of the liquid outlet chamber 4, the No. 1 elastic mechanism 9 and the No. 2 elastic mechanism 10 are fixedly connected to the corresponding sealing ball 8, and a cylinder is fixed on one side of the mounting block 2. The cylinder body 13 has an inner cavity connected to the liquid inlet cavity 3, a protective shell 14 is fixedly connected to one side of the cylinder body 13, a plunger 15 is slidably installed in the cylinder body 13, a push rod 16 is fixed to one end of the plunger 15 close to the protective shell 14, a motor 17 is fixed to the side wall of the protective shell 14, a turntable 18 is rotatably installed in the protective shell 14, a power shaft of the motor 17 passes through the side wall of the protective shell 14 through a bearing and is fixedly connected to the axial position of the turntable 18, a connecting rod 19 is rotatably installed on the outer edge of the side wall of the turntable 18, and the other end of the connecting rod 19 is rotatably connected to the push rod 16, and a connecting flange 7 is fixed to the side wall of the mounting block 2 at the positions corresponding to the liquid inlet 5 and the liquid outlet 6.
[0023] In this embodiment, in the initial state, the blocking ball 8 located in the liquid inlet chamber 3 blocks the liquid inlet 5 under the action of the first elastic mechanism 9, and the blocking ball 8 located in the liquid outlet chamber 4 blocks the through hole under the action of the second elastic mechanism 10. The motor 17 is used to drive the turntable 18 to rotate. During the rotation of the turntable 18, the connecting rod and the push rod 16 drive the plunger 15 to reciprocate along the inner wall of the cylinder body 13. When the plunger 15 moves away from the liquid inlet chamber 3, the internal pressure of the liquid inlet chamber 3 is lower than the external pressure, so the contaminants are not discharged. The sludge profile controlling agent will squeeze the No. 1 elastic mechanism 9, causing the sealing ball 8 to detach from the liquid inlet 5, and the sludge profile controlling agent enters the liquid inlet chamber 3 through the liquid inlet 5. When the plunger 15 moves away from the liquid inlet chamber 3, the sealing ball 8 in the liquid inlet chamber 3 will re-seal the liquid inlet 5 under the action of the No. 1 elastic mechanism 9. At the same time, the sludge profile controlling agent squeezes the sealing ball 8 in the liquid outlet chamber 4 through the through groove 95 and the through hole on the No. 1 elastic mechanism 9, so that the sludge profile controlling agent smoothly enters the liquid outlet chamber 4 and is finally discharged through the liquid outlet 6.
[0024] Embodiment 2:
[0025] See also Figure 1-4This embodiment provides a technical solution based on the first embodiment: the first elastic mechanism 9 includes a first sleeve 91 fixed on the side wall of the corresponding blocking ball 8, a first piston 92 is slidably installed in the first sleeve 91, a first movable tube 93 is fixed to the side wall of the first piston 92, one end of the first movable tube 93 slides through the side wall of the first sleeve 91 and is fixedly connected to the side wall of the liquid inlet chamber 3, the first movable tube 93 corresponds to the position of the through hole, a first spring 94 is fixed between the first piston 92 and the inner wall of the first sleeve 91, and a number of through grooves 95 are symmetrically opened on the side wall of the first movable tube 93.

[0027] In this embodiment, the No. 1 elastic mechanism 9 is used to cooperate with the sealing ball 8 to seal the liquid inlet 5, and the No. 2 elastic mechanism 10 is used to cooperate with the sealing ball 8 to seal the through hole. Compared with the traditional springs, the No. 1 elastic mechanism 9 and the No. 2 elastic mechanism 10 can effectively avoid the accumulation of solid particles in the oil sludge profile control agent in the gaps between the springs, resulting in the spring getting stuck after long-term use and unable to perform normal pumping operations. At the same time, during the compression process of the No. 1 elastic mechanism 9, the air in the No. 1 sleeve 91 will enter the No. 2 sleeve 101 through the connecting pipe 12, so that the sealing ball 8 in the liquid outlet cavity 4 can tightly seal the through hole. During the compression process of the No. 2 elastic mechanism 10, the air in the No. 2 sleeve 101 will enter the No. 1 sleeve 91 through the connecting pipe 12, so that the sealing ball 8 in the liquid inlet cavity 3 can tightly seal the liquid inlet 5, ensuring normal pumping operation.
