Description

Automatic open type well cleaner

Technical Field

The utility model belongs to the technical field of the washing and specifically relates to wash very effectively to the water injection well in oil field and oil well.

Background

In recent years, the oil field yield is reduced, the production time is long, the pipe wall of an oil well and a water injection well is scaled and thick, and the normal production of the oil field is seriously influenced. For this reason, oil fields have been cleaned by a large amount of manpower and material resources, and previously, oil fields and water injection wells have been cleaned by pulling well pipes out of the ground from well pipes and cleaning on a surface platform, that is, by cleaning moving pipes. The cleaning time is long, the time and the labor are wasted, the cost is high, the yield is influenced, and in the face of market demands, an advanced automatic opening type well cleaning device is designed to clean an oil well and a water injection well under the condition of no movement. Production practices prove that the automatic expansion well cleaner descaling has great advantages compared with chemical cleaning and high-pressure water spraying descaling.

The automatic open-type well cleaner utilizes the cavity jet principle, has thorough descaling, no damage to the pipe wall, no environmental pollution, low cleaning cost, manpower saving and closed cleaning. In 2017, the field cleaning experiment is carried out in Daqing oilfield oil extraction four-factory, and the practice proves that the well cleaner has reliable performance and thorough descaling. One well cleaner can clean 10 wells, has low cost, high efficiency and short period, and is accepted by the oil field industry.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that the cleaning distance of the existing oil field pipeline cleaning device is short and the efficiency is low, and provides an automatic open type well cleaning device.

The utility model relates to an automatic open clear well ware, including dragging for bolt 1, go up helmet 2, preceding blade 3, preceding center pin 4 and tighten up cap 5, back center pin 6, helmet 7, back blade 8, return spring 9 and automatic control part component that opens.

The automatic control opening control structure of the utility model consists of a sliding sleeve 10, a vertebral body sleeve 11 and a contact 12, and a connecting nut 14 is connected with other parts through a linkage rod 13.

The sliding sleeve 10 in the automatic opening control structure of the utility model is internally provided with a pawl 101 structure; a contact built-in spring 121, a cone 122; the contact is connected with the vertebral body sleeve 11 through the vertebral body 122; the vertebral body sleeve 11 is connected with the sliding sleeve 10;

the utility model discloses a blade dress is on the center pin.

The utility model discloses design and make pipeline cleaning equipment according to the cavitation effect principle in the hydrodynamics field. The well cleaner consists of elastic blades which are overlapped in a staggered mode, the well cleaner is placed into a pipeline during operation, the well cleaner moves forwards quickly under the pushing of water flow, due to the blocking of scale on the pipe wall, the water flow is accelerated suddenly through gaps of the blades to form a vortex rotating at the highest speed, a large number of bubbles are formed, the well cleaner is cracked instantly to generate strong jet flow, dirt is impacted and stripped, and the dirt removed is discharged out of the pipe along with the water flow, so that the cleaning purpose is achieved.

Detailed Description

The first implementation mode comprises the following steps: the automatic opening type well cleaner comprises a bailing bolt 1, an upper protective cap 2, a front blade 3, a front central shaft 4, a tightening cap 5, a rear central shaft 6, a protective cap 7, a rear blade 8 and a return spring 9; the automatic opening control part consists of a sliding sleeve 10, a vertebral body sleeve 11 and a contact 12, wherein the sliding sleeve 10 is communicated and connected with a return spring 9, a rear blade 8, a protective cap 7, a rear central shaft 6, a tightening cap 5 and a front central shaft 4 through a linkage rod 13; a pawl 101 structure is arranged in the sliding sleeve; a contact built-in spring 121, a cone 122; the contact is connected with the vertebral body sleeve 11 through the vertebral body 122; the vertebral body sleeve 11 is connected with the sliding sleeve 10.

The second embodiment: the embodiment further limits the connecting structure of the automatic opening type well cleaner, and the bailing bolt 1 is connected with an upper protective cap 2, a front blade 3 and a tightening cap 5 through a front central shaft 4; a sealing leather cup and a gasket are arranged in the cup; the blades are arranged on the central shaft; the protective cap 7, the rear blade 8 and the return spring 9 are arranged on the rear central shaft 6 and connected with the sliding sleeve 10.

The third embodiment is as follows: the embodiment limits the connecting structure of the automatic opening type well cleaning device, the front central shaft 4 is connected with the rear central shaft 6 through the connecting nut 14, and the linkage rod 13 penetrates through the two central shafts.

The fourth embodiment: automatic open clear well ware device of formula, water both produced thrust and made clear well ware remove forward, simultaneously, water acts as the transport means again, gets rid of the outside of tubes along with the rivers to the dirt that the efflux was clear away, the probability that produces the jam is little. During cleaning, different pressures and flows are selected according to different structural conditions, such as the well depth of 1000m and the scaling thickness of 5mm, the pressure of 10MPa and the flow of 50m are selected³And h, ensuring that the operation speed influences the cleaning quality. During cleaning, the generated waste liquid enters the tank car to form totally-enclosed cleaning, and the tank car is safe, efficient and environment-friendly.
