Embodiment Construction
[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0025] Such as figure 1 and figure 2 As shown, a method for cleaning impurities in the mine wall of an oil well adopts the following cleaning steps:
[0026] In the first step, the adjustment stage, the position of the balance unit is adjusted to ensure that the baffle plate 8 is vertical to the wellhead;
[0027] The second step is the lowering stage. On the basis of the adjustment in the first step, the power unit 6, the dredging pump 141, the hydraulic r...

The invention belongs to the technical field of petroleum drilling equipment, and specifically discloses a petroleum well mine wall mining impurity cleaning method. The petroleum well mine wall miningimpurity cleaning method comprises the following steps: step one, an adjusting stage: adjusting a baffle plate and a well opening to be in a vertical sate; step two, a putting stage: putting a powerdevice and a mechanism connected with the power device into a petroleum well through an inner retractable pulley; at the same time, putting a sludge box synchronously through an outer retractable pulley; step three, a cleaning stage: starting a water pump, using the water pump to convey water to a spray head through a pipeline, and spraying water mist onto the well wall by using the spray head; atthe same time, using a dredging motor to drive a rotary table and the spray head to rotate; at the same time, using a ramming arm to ram the well wall; step four, draining sludge inside a dredging pump to the interior of the sludge box; step five, a lifting stage: lifting the sludge box to the ground. According to the method, the cleaning and reinforcement of sludge on the petroleum well wall canbe realized, and successful operation of petroleum drilling operation is guaranteed.
Description
technical field [0001] The invention belongs to the technical field of petroleum drilling equipment, in particular to a method for cleaning impurities in mining walls of petroleum wells. Background technique [0002] Oil extraction is generally done by manually digging oil wells, and then oil is extracted in the wells. After drilling, oil wells generally need to go through a series of pretreatments on the oil wells to ensure the safety and efficiency of oil extraction. The cleaning of sludge, and the cleaning of oil well bottom sludge requires the use of specific sludge cleaning devices. [0003] But there are still deficiencies in the existing bottom-hole sludge cleaning device used for oil well drilling. When the general device enters the bottom of the well from the bottom of the well wall, the well at this time is just excavated, so the well The firmness of the wall is not high, so the soil on the well wall is easy to hang and fall into the bottom of the well as the devi...
