Development of Drilling Mud Solution for Drilling in Hard Rocks (RESEARCH NOTE)
Aim of the project is efficiency increase of hard rocks destruction at borehole bottom by developing drilling mud solution and evaluation of its influence on drilling process. The article presents the results of studies directed on studying of drilling mud composition (the choice of reagent concentrations, taking into account the filtration properties, structural and rheological parameters, stu...
متن کاملAcoustic identification of rocks during drilling process
Drilling into a rock massif is energetically extremely consumptive process. Hence the optimization of drilling regime with objective of energy consumption minimization, is very important. Proposed article discusses partial problem of this problem. During the drilling process it is useful to know the drilled rock type, whereas to particular drilled rock needs convenient drilling regime, which is...
متن کاملLake Bosumtwi Drilling Project: Shock Metamorphism in Rocks from Core
General context: Shock barometry via petrographic analysis helps to understand cratering mechanics, especially mass movements in the central uplift, including its collapse in the late stage of cratering. Shock pressures recorded in lithologies of the central uplift may exceed 45 GPa, e.g., in the Vorotilovo core drilled into the center of the Puchezh-Katunki structure [1]. In other craters, sho...
متن کامل“Explosive” Programming Controlled by Calculation
In the design of a functional library in the area of data-mining several algorithmic patterns have been identified which call for generic programming. Some of these have to do with flattening functions which arise in a particular group of hierarchical systems. In this paper we describe our efforts to make such functionalities generic. We start by a generic inductive construction of the intended...
متن کاملReactive-infiltration instabilities in rocks. Fracture dissolution
A reactive fluid dissolving the surface of a uniform fracture will trigger an instability in the dissolution front, leading to spontaneous formation of pronounced well-spaced channels in the surrounding rock matrix. Although the underlying mechanism is similar to the wormhole instability in porous rocks there are significant differences in the physics, due to the absence of a steadily propagati...
