Improving the quality of well reinforcement in the representation of the Umid-Babek field

High-quality drilling of gas and gas-condensate deposits on the world shelf, including in the Caspian Sea part of Azerbaijan, is of great national economic importance. For many years by the most advanced achievements, the wells were achieved to be drilled to the project depth, and the required amount of gas and condensate were successfully produced. Azerbaijan’s achievements in this field were realized at such a high pace that currently Azerbaijan has managed to export its natural resources to the European market. In our modern times, the penetration of drilling to greater depths and the occurrence of a number of complications have brought to the fore the application of the most advanced innovative approaches in well drilling technology and strengthening as well. One of the prospective fields mentioned is the ‘‘Umid-Babek’’ structure. Currently, the drilling operations are carried out on a very large scale and the most advanced technologies of the world drilling experience are applied in the mentioned field. Well reinforcement is one of the most difficult and responsible stages of well construction. It is no coincidence that due to high-quality reinforcement of the well, favorable conditions for the effective operation of the field are created. The most advanced technologies for the qualitative strengthening of casings are also applied in the ‘‘Umid-Babek’’ field. As a result of the researches, it was determined that if the well wall stability violation, absorption of drilling fluid and occasional manifestations are observed during drilling, the presence of more serious and effective complications is observed after the protective belt is lowered. First of all, injecting the required amount of cement solution behind the casing lowered into the well, making sure that this solution completely covers the annular space, and finally, the formation of qualitative cement is one of the actual problems. In the presented article, some directions of technological solutions related to the strengthening of wells in the ‘‘Umid-Babek’’ structure were presented.
