Novel petroleum exploitation auxiliary device

Abstract

The invention relates to a novel petroleum exploitation auxiliary device. The novel petroleum exploitation auxiliary device comprises a bracket, a cylinder body and a cylinder cover, wherein the bottom end of the left side of the cylinder body is provided with a petroleum inlet, and the top end of the right side of the cylinder body is provided with a petroleum outlet; a first motor and a speed reducer are arranged on the cylinder cover; the output shaft end of the speed reducer is connected with a rotating shaft; a bearing is arranged at the bottom end in the cylinder body, and the bottom end of the rotating shaft is fixedly connected with an inner ring of the bearing; a spiral blade is arranged on the rotating shaft, and blade holes are formed in the spiral blade; an annular heating cavity is arranged on the vertical outer side wall of the cylinder body, and an electric heater is arranged in the annular heating cavity; the top of the left side and the bottom of the right side, of the annular heating cavity, are separately provided with a liquid inlet and a liquid outlet, and a second motor is arranged at the top of the right side of the annular heating cavity; a plurality of mixing blades are arranged at the left end of an output shaft of the second motor; and the vertical outer side wall of the annular heating cavity is sequentially coated with a heat preservation layer, a thermal insulating layer and a wear-resistant layer. By adopting the structure, the novel petroleum exploitation auxiliary device can fully and uniformly heat petroleum and also effectively ensures the normal delivery of petroleum.

Description

technical field [0001] The invention relates to a novel auxiliary device for oil exploitation. Background technique [0002] As an important lifeline of the economy, oil has a huge impact on social development and daily life, and oil extraction and transportation have become an important link in the process of oil utilization. In the process of oil production, it is often necessary to use production auxiliary devices to heat and reduce the viscosity of the crude oil extracted from the well to be transported to the combined station, while the mixed fluid of crude oil and water is often heated and transported at the wellhead, which often flows when it flows. Oil-water separation occurs, so the heating of the fluid in the auxiliary device is not sufficient and uniform, so that the temperature required for transportation cannot be reached; in addition, due to the high wax content of petroleum and the high oil concentration, the oil in the auxiliary device is also It is easy to ...

In the process of oil production, it is often necessary to use production auxiliary devices to heat and reduce the viscosity of the crude oil extracted from the well to be transported to the combined station, while the mixed fluid of crude oil and water is often heated and transported at the wellhead, which often flows when it flows. Oil-water separation occurs, so the heating of the fluid in the auxiliary device is not sufficient and uniform, so that the temperature required for transportation cannot be reached; in addition, due to the high wax content of petroleum and the high oil concentration, the oil in the auxiliary device is also It is easy to produce the phenomenon of sticking and extending to blockage, which greatly affects the normal exploitation and transportation of oil, and also greatly reduces the performance of auxiliary devices
