Description
Technical Field
The invention relates to the technical field of oil well development, in particular to an acid squeezing device for acidification and blockage removal of an oil well.
Background
The oil well is a channel for exploiting oil, which rises from the bottom of the well to the top of the well according to the hole drilled by the well-arrangement system planned by the oil field development. An oil well is a borehole drilled by a drilling method. After drilling oil layer, the oil layer casing is set, and the cement is injected into the annular space between casing and well wall to maintain well wall and seal oil, gas and water layer. The oil-gas reservoir is a porous rock stratum deep in the ground, an oil production pipeline needs to be deeply inserted into an oil storage layer in the oil extraction process, oil in the oil storage layer is extracted, the area of the oil storage layer close to the oil production pipeline is called a near wellbore zone, and in the long-term oil extraction process, due to the difference of water quality and an extraction mode, gaps of the near wellbore zone can be blocked, so that the permeability of the gaps is reduced, further the permeability of the near wellbore zone is reduced, the oil production of an oil production well is reduced, and therefore the near wellbore zone needs to be unblocked.
In order to guarantee that the oil well can not be blocked up this moment, adopt the device to unblock the inside of oil well usually, the stifled operation is realized utilizing dredging pipe or chemical mode to the stifled device of unblocking that uses at present, but use dredging pipe to unblock when operating because dredging pipe carries out rigid contact with the inside of oil well always, will lead to dredging pipe itself to receive great pressure this moment to the lateral surface that leads to dredging pipe receives great wearing and tearing, will lead to the life-span of dredging pipe itself to subtract short after long-time use, influence the use.
In the blockage removing process of the oil well, the outer side face of the dredging pipe is required to be always in contact with the side face of the oil well, the effective blockage removing and dredging effect can be achieved, however, in the actual oil well, the diameters of all parts of the oil well are not completely the same, and the diameter of the dredging pipe is fixed and unchanged, so that the dredging pipe cannot be in contact with the inner side face of the oil well for a long time in the actual dredging process, the dredging effect is obviously reduced at the moment, and the dredging efficiency is influenced.
Meanwhile, in order to guarantee the dredging effect, chemical agents are generally used for dissolving organic matters in the oil well and then dredging pipes and other devices are used for realizing the dredging effect, but when the chemical agents are put into the oil well, the chemical agents cannot be guaranteed to be fully contacted with the inside of the oil well, the chemical agents at all parts in the oil well are not uniformly distributed, the blockage removing effect of the chemical agents is greatly reduced, and the blockage removing effect is influenced while the waste of the chemical agents is caused.
