Abstract
The utility model relates to a double spiral water well cleaner, which relates to an device used in the oil field to carry out dirty eliminating for the watering well. At present, the scale formation of the watering well in the oil field is very serious, and the existing drifting implement is of a complex structure and uneasy operation, which is difficulty to use, and the successful rate of dirty eliminating is low, and the accident is easy to take place. The utility model comprises a cylinder body(1) with a cone shaped end head(1-1), and two groups of dirty eliminating plates(2) are positioned on the cylinder body(1) in an opposite direction. Each group of dirty eliminating plates(2) is embedded on the cylinder wall in a spiral manner, and a spring(3) is positioned inside the cylinder body(1), and one end of the spring(3) is touched with the cylinder body(1) with the other end touched with the dirty eliminating plates(2). The utility model is of a simple structure, safe operation and good dirty eliminating effect. The dirty eliminating rate of the utility model for the water well is more than 80 percent through testing, which is beneficial for spread and use.
Description
Technical field: the utility model relates to a kind of device that water injection well is carried out scale removal that uses on the oil field.
Background technology: at present, water injection well scale problems on the oil field is very serious, fouling brings difficulty for water filling and test, and the problem that existing shows loving care for does not intake, do not go under the tester causes damage thereby produce to the oil field, present apparatus for eliminating sludge mainly is drifting device and some drifting equipment of self-control, because drifting device complex structure is not easy operation, so should use difficulty, and the success rate of its scale removal is low, occurs accident easily.
The utility model content: the purpose of this utility model is to provide a kind of water injection well stay-furring tool of simple in structure, handling safety, it comprises the cylindrical shell 1 that has cone-shaped end 1-1, described cylindrical shell 1 is provided with two groups and is the scale removal sheet 2 that rightabout is provided with, every group of scale removal sheet 2 is embedded on the barrel twist, be provided with spring 3 in the inside of cylindrical shell 1, one end of described spring 3 contacts with cylindrical shell 1, and the other end of spring 3 contacts with scale removal sheet 2.With the rear end of stay-furring tool of the present utility model be put in the water injection well after weighted lever is connected, the scale removal sheet stretches out outside the cylindrical shell under spring action, stretch out the outer scale removal sheet of tube and be the incrustation scale on the scraping water filling borehole wall, the scale removal sheet of two groups of different directions is worked simultaneously and can be removed incrustation scale on the borehole wall completely, when running into thicker incrustation scale, the scale removal sector-meeting is compressed within the cylindrical shell, avoided the scale removal sheet to be damaged like this, only need to carry several times gravity rod during operation causes the scale removal sheet how several times the scraping incrustation scale can be with the incrustation scale full scale clearance more, the scale removal sheet of U-shaped cross-section can make incrustation scale and the current removed together flow through along U-lag, avoided because the problem that the stay-furring tool resistance can't be worked too greatly, the utility model is simple in structure, handling safety and features high scale-removing effect, after tested, the utility model, is beneficial to and applies more than 80% the descaling rate of incrustation scale in the well.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
The specific embodiment: present embodiment comprises the cylindrical shell 1 that has cone-shaped end 1-1, described cylindrical shell 1 is provided with two groups and is the scale removal sheet 2 that rightabout is provided with, the cross section of described scale removal sheet 2 is a U-shaped, the U-lag 2-1 of U-shaped scale removal sheet can make incrustation scale and the current removed together flow through along U-lag, avoided to work because the stay-furring tool resistance is too big, every group of scale removal sheet 2 is embedded on the barrel twist, spirality scale removal sheet can carry out scale removal to each position in the borehole wall uniformly simultaneously, be provided with spring 3 in the inside of cylindrical shell 1, one end of described spring 3 contacts with cylindrical shell 1, the other end of spring 3 contacts with scale removal sheet 2, can compress spring when scale removal sheet 2 runs into thicker incrustation scale contracts to inner barrel, avoid the scale removal sheet to be subjected to the damage of incrustation scale, when incrustation scale is thin, the scale removal sheet stretches out and carries out scale removal outside the cylindrical shell under the effect of spring, the installation of spring can adapt to the scale removal sheet incrustation scale of different-thickness is removed, also be provided with delivery port 1-2 on the cylindrical shell 1, delivery port 1-2 has avoided in the cylindrical shell 1 water inlet too much to make barrel pressure excessive and influence operating efficiency.
