Application of this method is one of the effective tools to eliminate sticking and failures of the equipment in the wells, including the small diameter wells, as their design features do not allow using downhole jacks and other equipment of required capacity.
In the course of drilling, operation and wells workover oilmen often face problems resulting from tools jamming, breakage of pipe strings and cables of electric centrifugal pumps (ESP), sticking of geophysical instruments and some other problems. Previously used technologies required performance of a number of preparatory operations, which required additional time and expenses. All this affected the success ratio of the operations performed.
The design and technology of working with application of a wellhead vibrator developed by TatNIPIneft experts allows to effectively eliminate various downhole complications. This method uses self-energy elastic vibration of the emergency tool string assembly that allows reducing the loads on the pipes and the lifting assembly used.
The cost-effectiveness of the engineering design application for one well operation is 52.5 thousand rubles.
