Method of increasing the strength of well casing strings under plastic flow of salts by active resistance method

The research is aimed at developing a new method of active resistance of deep well casing strings to increase their strength and durability under conditions of plastic salt flow. This study used methods of systematic analysis of geological conditions, design of well structures and evaluation of the effectiveness of fastening technologies aimed at solving problems related to drilling and operation of wells in difficult geological conditions of Turkmenistan. The conducted experiments have shown that the use of this method allows for reducing deformations and minimizing the risk of string damage in complex geological conditions. The data analysis showed that the applied method is able to increase the operational life of strings, which is a significant achievement in the field of drilling technologies. In addition, a comparative analysis with traditional methods confirmed the economic feasibility of the new approach, as it reduces maintenance and repair costs. Additionally, the results of the study revealed that the use of the new method leads to a 25 per cent reduction in the probability of cracking and fracture formation in casing strings compared to conventional approaches. It was also found that the method actively influences drilling dynamics by reducing the time it takes to raise and lower the string into the well, which improves the overall efficiency of drilling operations. Finally, the findings open up prospects for further study of the influence of different geological conditions on active drag efficiency, which may contribute to the creation of more adaptive and sustainable technologies in drilling practice.
