Definitions

  • Another method of stimulating the production of petroleum wells is to shut down the lime in the process by introducing an acid (patent 220, 37 37).
  • an acid (patent 220, 37 37). 5 'It is deprived of the above-mentioned disadvantage, but its disadvantage is a limited use, because it can be easily accessed due to the lack of access to the device. Otherwise, the use of acid results in increased well-being.

Then, the hole of the well was equipped with a device that allows you to keep the 15 specified output from the well ⁇ and to change it all the same. In this case, in the quality of such a device, a slide valve was used. In addition, a pressure gauge was installed at the end of the well, as a rule, a pressure gauge was used, and in the end, a pressure gauge was used to measure 20 pressure.
