The invention relates to the technical field of rock detection, in particular to a rock formation pressure simulating detecting device and method. The rock formation pressure simulating detecting device comprises a base platform, a supporting piece and a detecting mechanism; the detecting mechanism comprises a torsion drive mechanism, a connecting piece, an annular fixing piece and at least two arc-shaped clamping pieces; the two ends of the connecting piece are connected with the torsion drive mechanism and the annular fixing piece correspondingly; the arc-shaped clamping pieces are uniformly arranged on the inner wall of the annular fixing piece; a plurality of electromagnetic force loading mechanisms are uniformly arranged on the arc-shaped clamping pieces; and a positioning mechanism is further arranged on the base platform. According to the rock formation pressure simulating detecting device, an object to be detected is fixed on the base platform through the positioning mechanism, torsion can be applied to the object to be detected under the effect of the torsion drive mechanism, dynamic pressure is applied to the object to be detected through the electromagnetic force loading mechanisms, and a mechanical environment of rock under the complex formation pressure is simulated, so that mechanical properties are detected more precisely, and quicker and more precise detecting equipment is provided for obtaining and studying mechanical parameters of the formation rock.
Description
technical field [0001] The invention relates to the technical field of rock detection, in particular to a rock formation pressure simulation detection device and a simulation detection method. Background technique [0002] In oil and gas drilling engineering, the mechanical properties of formation rocks are necessary basic technical parameters, and it is very important to obtain the mechanical properties of drilling-encountered formation rocks in a timely and accurate manner. [0003] The traditional methods to obtain formation rock mechanical parameters are coring experiment method and logging data prediction method. The coring experiment method is to take out the actual drilled cores of the formation in blocks, and then process them into the required rock samples for mechanical testing. This method is difficult, costly, and takes a long time, and the mechanical parameters of the formation rocks cannot be obtained in time. The logging data prediction method is an indirect ...
