ANALYSIS OF WASHING SOLUTIONS FOR OPENING PRODUCTIVE FORMATION IN WELL DRILLING

Abstract

The article deals with the selection of fluid solutions used in the drilling of oil and gas wells. As it is known, with the increase of the depth, the liquid expands and its density decreases. When determining the hydrostatic pressure of a fluid, it is recommended to take into account the change in temperature depending on the depth of the well. To do this, it is important to accurately determine the law of temperature change depending on the depth of the well. The quality of the solutions used in drilling a well depends on its basic physical properties. Thus, with a change in depth, reservoir pressure and temperature increase. Therefore, determining the density of the solution for optimal depth intervals is of great importance. The article recommends the use of quality washing solutions, such as well drilling fluid.
