Abstract

The invention relates to an intellectual high temperature high pressure dynamic stopping leak appraisal device in the field of oil exploration and development excremental device. it is formed by a gas source, a mud pump, a piston-type high temperature high pressure mud bottle, a steel leaked bed holder, a work holder, a rock core holder, a flow-meter, an electric dissimilar, a ring pressure pump, a return pressure controller, a liquid circulating pipe, a control line, a data collector, a computer and a printer and so on. It arranges the drilling fluid of the leak agent into the mud bottle on the condition of temperature, pressure, flow speed of the simulated formation; it then uses mud pump to drive the borehole fluid of the piston-type high temperature high pressure mud bottle and dose leak damage experiment to the steel leaked bed holder, the artificial slit plate and the formation rock core to achieve the indoor correct evaluation of the leak effect of the drilling fluid and the well completion fluid.

Description

Technical Field: [0001] The invention relates to an intelligent high temperature and high pressure dynamic plugging evaluation experimental instrument for evaluating the plugging efficiency of plugging materials in drilling fluids and completion fluids under the conditions of simulating formation temperature, pressure and mud flow in the petroleum industry, belonging to oil and gas layer protection in petroleum exploration and development Field of experimental equipment. Background technique: [0002] During the drilling process, formation leakage often occurs. Failure to plug the leakage layer in time will seriously affect the normal progress of drilling operations. Formation leakage is closely related to factors such as rock physical properties, bottom hole pressure difference, and the type and size of plugging materials added to the mud. At present, there are only API indoor static plugging evaluation experimental devices at home and abroad. The steel ball leakage bed is insta...
