Abstract: The present disclosure provides an edge and bottom water invasion simulation apparatus and method, a storage medium, and a product. A controller controls an inert gas to be injected into a first intermediate container, and stops the injection. The controller controls formation water to be injected into the first intermediate container, and stops the injection. The controller controls the first intermediate container to be communicated with a core holder, and adjusts a pressure of a back pressure valve, so that the formation water enters a core to simulate edge and bottom water invasion. In the present disclosure, by adding the inert gas and the formation water to the intermediate container, an infinite edge and bottom water with sufficient energy at an early stage of a water invasion and a limited edge and bottom water with lower energy at a later stage of the water invasion can be effectively simulated.

Abstract: A method for evaluating rock drillability by a nano-indentation test on a rock cutting includes: conducting a nano-indentation test on a rock cutting sample, acquiring a displacement-load curve of an indenter, and calculating a micro-hardness under the nano-indentation test; calculating mineral composition of the rock cutting sample based on a statistical distribution characteristic of the micro-hardness, and transforming the micro-hardness under the nano-indentation test on the rock cutting sample into a macro-hardness; and calculating a rock drillability grade characterized by the micro-hardness under the nano-indentation test on the rock cutting sample based on a correlation between the macro-hardness of the rock cutting sample and the rock drillability grade. In the context of few downhole rock samples and high cost, the method overcomes the limitation of sample size and shape on conventional testing and solves the difficult problem of mechanical parameter testing of deep rocks.
