Abstract:

The Tengiz field of the Republic of Kazakhstan has an exceptionally complex geological and physical structure. Nevertheless, the results of the pilot production of the deposit and the very large complex of research works carried out by «Tengizchevroil» (a detailed computer geological and physical model of the deposit and then a hydrodynamic three-dimensional multi-phase computer model based on it) allow us to outline the current ways The most effective development of this one of the largest deposits of the world. The main methods of hydrodynamic studies of wells in the Tengiz field are considered in the article, and important conclusions were made about the mechanism for increasing the productivity of the Tengiz field wells as a result of various studies.

Keywords: hydrodynamic studies of wells; analysis of well testing under unsteady conditions; analysis of the results of well and formation hydrodynamic studies; characteristic of productivity and modes of wells and formations; control over the development of reserv
