Reproducing Quantitatively and Realistically the Fragmentation Process Documented in Rock Cutting Experiments

While domestic oil reserves are still adequate, such supplies are increasingly concentrated in geological issues and complex operating environments such as deep sea, deep sea deep sea and low permeability formation. Drilling a well in a reservoir is an expensive and time-consuming task. In deep wells, permeability (ROP) is one of the main problems. A low ROP (eg, 3 to 5 feet per hour) is primarily a result of an increase in compressive strength of highly overloaded strata encountered at greater depths.

Raised - A structurally high area of ​​the crust caused by elevated rock movements, like a broad dome or an arch. Weather - Pressure and temperature on or near the surface of the Earth with little or no movement of process material due to chemical or physical destruction of rocks due to exposure to atmospheric substances.

Rocks exposed to the atmosphere are unstable and susceptible to weathering and erosion. Due to weathering and erosion, the original rocks are crushed finely and dissolved substances are carried away. This broken material accumulates and is filled with other materials. The sand of a single particle is still part of the rock formed by it, but rocks of these fused particles are deposited. Sedimentary rocks are formed by calcification of these buried small fragments (clastic sedimentary rocks), accumulation of substances produced by organisms and calcification (biotic rocks - fossils), or by calcification of chemical precipitation substances including minerals in solution It is formed. Evaporation (precipitate sedimentary rocks). Due to erosion processes and organic matter (such as plant debris), clastic rocks may be formed by all kinds of large rock fragments.

Sedimentary rocks are formed on the surface of the earth by the deposition and consolidation of initial rocks, minerals and organic debris or as chemical deposits and organic growths (sediments) in water. This process leads to deposits, debris deposits (rock fragments) and organic particles (crushed stone) deposits, or chemical deposits of minerals from the solution (evaporative rock). The pellets are then compressed and anchored (sequential action) at moderate temperature and pressure.
