Description

rotating vane impact type heavy hammer combined type drifting tool device

Technical Field

The utility model relates to a water injection well field especially relates to a rotating vane impacted style weight combination formula drifting tool device.

Background

In the water injection well test, the phenomenon that a test instrument is blocked underground often occurs. The accumulation phenomena of mud, sand, polymer and the like in the pipe column are in the long-term injection process, the mud and the like are gradually accumulated at the bottom of the well, and when the mud, the sand, the like are accumulated above the eccentric water distributor, the water absorption condition of the lowest layer is poor or water is not absorbed, so that the accumulation speed of the polymer solution in the water injection pipe column is accelerated. Most of injected water of the water-drive injection well is sewage, and some injected water contains sand grains and small stones, which are injected into a downhole tubular column along with the injected water. When the sand is injected into the stratum through the eccentric water distributor, the sand with large grain size is filtered by a filter screen of a blanking plug in the eccentric water distributor and deposited at the bottom of the well for accumulation, and the accumulation body of the sand and small stones is thicker and thicker along with the increase of time. At this time, if the well is washed back in time, sand grains and small stones can be washed to the ground. When the concentration of dissolved salts in water is lower than the concentration product of ions, the salts still exist in the water in an ionic state, and once the concentration of the dissolved salts in the water reaches a saturated state, the catalytic action of metal surfaces and impurities of equipment on the crystallization process promotes the supersaturated salt solution to separate out crystals to form scale. The rate of scale formation is exacerbated if the lowermost waterflooding interval absorbs very little or no water. When the pipe scale forms a certain thickness, the test instrument will be blocked. Before the underground falling object instrument is put into the well, the testing instrument is not checked in place. Downhole tool usage and tool quality issues. For example, the aging and the running of the rubber of the packer under the condition of long-term water injection, the operation construction quality, the isotope test and the like are easy to cause the blockage situation.

At present, different modes of different geological oil layers of various factories are different, but most of the factories adopt large-discharge well washing, sand washing and dredging tools to dredge the well and remove the blockage.

In the case of Daqing oil field, the well dredging tools at present are roughly 6 types of heavy metal tungsten steel weighted polish rod well dredging devices, flat shovel type well dredging devices, threaded well dredging devices, diamond scraping well dredging devices, blade type well dredging devices and cone type well dredging devices.
