RESEARCH AND SELECTION OF A VOLTAGE PULSE GENERATOR FOR DRILLING WELLS IN COMPLEX GEOLOGICAL CONDITIONS OF THE KAMCHATKA REGION
Annotation. The global volume of exploratory and industrial drilling for various purposes is constantly increasing. Mechanical drilling faces challenges such as low penetration rates, reduced reliability, and short service life of drilling tools (drill bits), especially when drilling hard and very hard rock formations. A particular challenge is the drilling of large-diameter wells (over 300 mm). Traditional drilling methods have practically exhausted their potential for significantly increasing drilling productivity (speed). Therefore, fundamentally new drilling methods are being explored. One such innovative method is electroimpulse (electro-pulse) drilling, which is based on rock destruction through electrical impulse breakdown. Thus, the relevance of this study is determined by the s ignificance of the problem, the promising nature of electro-pulse drilling technology, and the need to develop recommendations for selecting a voltage pulse generator (VPG). The main objective of the work is to research and select a VPG suitable for well construction in the complex geological conditions of the Kamchatka region. The primary task involves performing calculations, analyzing equipment characteristics, and developing a methodology for selecting a generator that ensures high efficiency in rock destruction with minimal energy consumption. The performed calculations allowed determining the key parameters of a voltage pulse generator (VPG) that ensure efficient drilling in the complex geological conditions of the Kamchatka region. It was established that for breaking hard rocks when drilling wells with a diameter exceeding 300 mm, a generator with an output pulse energy of 764–1709 J, power of 2.5–5.1 kW, and voltage up to 402 kV (accounting for cable losses) is required.
Keywords: electro-pulse drilling, generator power, cable resistance, inductive resistance, electric current intensity, output voltage, pulse energy.
