The study of hydraulic hammer device in drilling tool assembly in hydraulical rotary drilling

Abstract

The article presents the study of a hydraulic hammer device for rotary well drilling. The mathematical model of the hydraulic hammer device has been described and studied, the relation of the dynamic load changes on the rock-destruction tool from the principal parameters of the hydraulic hammer device have been obtained. The trial rotary boring with the use of a hydraulic hammer device in drill tool assembly has been carried out, an increase in the drilling penetration rate has been achieved by 47%.

Substantiation of geological exploration and modeling of oil deposits for multistage fracturing in a horizontal well

“…Geological factors include: current net thickness of the reservoir, current oil and water saturation, clay and sand content, coefficient of the layer-by-layer heterogeneitynumber of reservoir beds, bound water, distance to the water-oil contact (which affects the initial water cut), porosity, permeability and flow capacitty, the current density of recoverable reserves per well. In the presence of complicating structural tectonic elements such as shears, faults, fractures, it is necessary to know the stress of the main stress axes and the geomechanical parameters that will affect the productivity after hydraulic fracturing [4,5].…”

Labor Productivity Forecasting

“…The use of the time factor makes it possible to reduce autocorrelation in the time series and improve accuracy of the calculated values, since it takes into account long-term changes that are not associated with the changes caused by the factors included in the model [5].…”

Linguistic Borrowing as a Way to Enrich Oil and Gas Terminology

“…However, this terminology formation method is not always applicable. Therefore, the terms are often formed on the basis of secondary nomination methods: rethinking, metonymic transfer [9].…”
