Embodiment 1

[0033] Such as Figure 1-Figure 6 As shown, the device for avoiding the narrowing of the crude oil channel in the oil well of the present invention includes a suspension device and a wax removal assembly sequentially connected, the suspension device drives the wax removal assembly to move vertically, and the wax removal assembly includes a connecting shaft 1, a support Plate 2, scraper assembly, driving device I, driving device II and installation cylinder 5 sleeved on the connecting shaft 1, one end of the connecting shaft 1 is connected to the supporting plate 2, and the axis of the connecting shaft 1 is perpendicular to the supporting plate 2 , the driving device I is located on the support plate 2, and can drive the installation cylinder 5 to rotate around the axis of the connecting shaft 1;

[0034] Described scraper assembly comprises support shaft 3 and support cylinder 4, and one end of described support shaft 3 is connected with the sidewall of installation cylinder 5...

Embodiment 2

[0037] The present invention is based on embodiment 1, and the present invention is further described.

[0038] Such as Figure 1-Figure 6 As shown, the present invention avoids the narrowing of the crude oil channel in the oil well, the support shaft 3 is bent into a C shape, and its ends are connected to the side wall of the installation cylinder 5, and the support cylinder 4 is located on the support shaft 3 away from the installation cylinder 5 on the shaft.

[0039] The cross section of the scraper 6 is triangular, its base is connected with the support cylinder 4, its waistlines are all arc-shaped, and the inner concave surface of one waistline faces the center of the triangle, and the inner concave surface of the other waistline faces away from the center of the triangle. the center of the triangle.

[0040] The cross-section of the scraper 6 is set as a triangle, and the two waistlines are arcs, which is beneficial for the scraper 6 to scrape off the wax layer on the...

Embodiment 3

[0045] The present invention further describes the suspension device on the basis of Embodiment 1.

[0046] Such as Figure 1-Figure 6 As shown, the present invention avoids the narrowing of the crude oil channel in the oil well, the suspension device includes a fixed wheel 11, a winch 9 and a wire rope 10, one end of the wire rope 10 is connected with the winch 9, and the other end of the wire rope walks around the fixed wheel After 11, it is connected with the connecting shaft 1, and the winch 9 makes the connecting shaft 1 move along the axis perpendicular to the horizontal plane by retracting and unwinding the wire rope.

Abstract

The invention discloses a device for preventing a crude oil channel in an oil well from being narrowed. The device for preventing the crude oil channel in the oil well from being narrowed comprises a suspending device and a wax removing assembly which are connected in sequence, the wax removing assembly comprises a connecting shaft, a support plate, a scraping knife assembly first driving device, a second driving device and a mounting cylinder, the connecting shaft is connected with the support plate, and the first driving device can rotate around an axial line of the connecting shaft; the scraping knife assembly comprises a support shaft and a support cylinder, one end of the support shaft is connected with the mounting cylinder, the other end of the support shaft penetrates through the support cylinder to be connected with the mounting cylinder, and the second driving device drives the support cylinder to rotate; the side wall of the support cylinder is provided with several scraping knifes. The suspending device puts the wax removing assemblies into the oil well which needs wax removal, then the first driving device and the second driving device are started to make the scraping knife remove wax on the wall of the oil well, which further avoids the generation of negative conditions that a crude oil flow channel is reduced, the oil pressure is increased, and an oil pipe is clogged to guarantee normal flow of crude oil and successful proceeding of crude oil exploitation.

Description

technical field [0001] The invention relates to wax removal equipment, in particular to a device for avoiding the narrowing of crude oil channels in oil wells. Background technique [0002] Drilling is the project of using mechanical equipment to drill the formation into cylindrical holes with a certain depth. According to the way of rock crushing and the type of tools used, it can be divided into ton drill and rotary drill. [0003] Ton drill, also known as impact drill. The drill bit is sent to the bottom of the well with a wire rope, and the beam mechanism is driven by power, so that one end of the beam moves up and down, and the wire rope and the drill bit are driven to produce an up and down impact to break the rock. The drilling speed of sudden drilling is slow, the efficiency is low, and it cannot adapt to the drilling requirements of increasing well depth and complex formations, and is gradually replaced by rotary drilling. But it has the advantages of simple equi...
