Features of colmatation zones of a productive formation in terms of rotary drilling by drilling muds are considered. A brief analysis of the most popular decolmatation methods is performed. Special attention is paid to the decolmatation method involving implosion effect. An example of one of the existing installations is represented with following consideration of its application features. A new principally different installation, free from the disadvantages found in the available one, is considered; a patent for the installation is obtained in Kazakhstan. It does not involve tubing with its packer and wellhead sealing. It also does not require a compressor and its manifold. Characteristic features of the newly developed installation for creating implosion effect are represented; its operation at producing both single and any number of repeated implosion acts is examined. A mathematical analysis is performed to calculate the empty space limits required for the implosion effect by a criterion to prevent casing string collapse by hydrostatic pressure of the drilling mud remained in the annular space. An example of dependency of the maximum permitted length of empty space in the casing string on its mechanical strength and its wall thickness, calculated by means of a computer program, is represented.

“…To eliminate complications arising from poor-quality well cleaning and energy costs increase, significant funds are spent, and it is often necessary to change approaches to individual drilling processes (Vytyaz et al, 2015;Ziaja et al, 2017). This situation occurs despite the observance of the general recommendations of the flushing process and the requirements of the technical and technological documentation developed for the specific conditions of a particular well.…”

The main factors affecting the efficiency of the carrying capacity of drilling fluid are analysed in the paper. A description of the design of an experimental setup for modeling the well flushing process is presented, which makes it possible to evaluate the efficiency of the carrying capacity of a fluid from a variety of factors under study. To conduct experimental studies of the influence of factors on the efficiency of cleaning wells from cuttings, an experimental plan was built using the Taguchi methods for six factors at three levels of their change. According to the plan, we studied the effect of such parameters on the carrying capacity of the drilling fluid at various values of its flow rate: the variability of the drill string in the well; the cuttings particle diameter; the plastic viscosity of the drilling fluid; the pulsation frequency; the rotation of the drill string and its longitudinal movement. The nature of the formation of stagnant rock zones in the annulus of directional wells has been assessed. The influence of factors according to the constructed plan of the experiment at the distance of the beginning of settlement of the cuttings was studied. Based on the results of the studies, it was found that changing the range of these factors reduces the volume of rock deposited on the lower wall of the directional wellbore. It has been established that the use of a pulsating flow of flushing fluid makes it possible to reduce the value of its consumption and improve the efficiency of cleaning the annular space of wells from cuttings.
