Abstract: the article reviews the analysis and provides recommendations, as well as instructions for the correct choice of rock-breaking tools for directional and horizontal wells in the Western part of the oil and gas fields of Turkmenistan for the purpose of trouble-free wiring and to increase mechanical speed during construction. To analyze the choice and mode of operation of rock-breaking tools, materials were used for working out previously drilled wells, with geological characteristics of deposits and physical and mechanical properties of rocks, stratigraphy (lithological section), and data on the durability of bits and mechanical speed obtained from the results of working out bits. This paper presents a detailed analysis of the created load on the bit and considers the effects of transverse loads on the bit, the difficulties of drilling directional wells, their specific causes. There are also recommendations for choosing the mode of drilling drill bits and operating instructions for different types of rock-breaking tools. This work can be used to perform the assigned tasks in the construction of oil and gas wells with complex geological characteristics.
Key words: bit, vibration, crack, sludge, torque, load, cutting element, downhole motor, layers, shoe, support.
