INNOVATIVE APPROACHES TO THE CONSTRUCTION OF OIL AND GAS WELLS IN THE CONDITIONS OF TECTONIC DISTURBANCE OF THE EAST SIBERIAN SECTION

Annotation. The development of drilling technologies in regions with complex tectonic structures is accompanied by the impact of factors caused by discontinuous tectonics and high fracturing of rocks. The most dangerous manifestations include intensive absorption of flushing fluids, karst voids, high permeability zones and abnormal filtration channels, which create conditions for emergencies and reduce the technical and economic performance of well construction. These processes lead to an increase in technological risks, an increase in the duration of drilling operations and an increase in the cost of field development. The paper analyzes modern technological solutions used in the construction of oil and gas wells in the fault-block structure of the sedimentary cover of Eastern Siberia. It is shown that production drilling in zones of tectonic disturbances is characterized by the development of instability of the trunk walls, water occurrences, gas dynamic effects and deviations of the well trajectory due to the heterogeneity of the stress-strain state of rocks. Special attention is paid to substantiating the use of specialized technologies aimed at increasing the stability of the trunk, limiting filtration losses and ensuring controllability of the trajectory in conditions of fault structures. An assessment of their technological feasibility and practical effectiveness in the development of deposits in Eastern Siberia has been carried out.
Keywords: oil and gas wells, tectonic disturbance, fault zones, drilling complications, trunk stability, aerated systems, pneumatic impact technologies, safety improvement.
