The use of intelligent systems when killing fluids with anomaly high formation pressures (Achimov deposits)

Purpose. Description of effective methods of killing wells with AHFP using intelligent systems. Search for solutions for new approaches and breakthrough technologies in the field of well killing.

Materials and methods. Now, various technological solutions have been tested and approaches have been determined for each type of wells, allowing to regulate the technological process. However, working with the Achimov formation requires high-tech methods. Killing wells is the first preparatory stage before the start of the well life cycle or already in the process of production before planned workovers, and it is at this stage that it is necessary to concentrate on new technologies, calculations and the operational process. This article proposes for consideration one of the promising methods of killing wells using digital products and automated equipment. Examples of killing process modeling and obtaining data on completion of work in the form of graphic images are given. A comparative analysis of indicators of actual and planned performance of work was carried out. The convergence of results during well killing was 99%.

The proposed method improves the quality of well killing operations and is a technological breakthrough. In addition, killing wells using digital products will make it possible to more accurately generate calculations, reduce the impact of the human factor, preserve the production characteristics of the well and ensure an increase in the turnaround time.

Results. The development of a software package for well killing will make it possible to eliminate the overspending of the solution and reduce the cost of additional volumes in the process of well killing.

Conclusion. Thus, the software is necessary for modeling the process of circulation and well cleaning, hydrodynamic losses, and performing calculations of effective replacement of solutions with other process fluids. Additional field trials are required to introduce this product.
