A simulation device for integrated evaluation experiment for sand control wellbore plugging and plugging removal, including a wellbore system, a whole sand control well plugging system, a local sand control well plugging system and a plugging removal system. The wellbore system simulates downhole working conditions of the sand control wellbore. Perforations of the whole sand control well plugging system and sand-filled pipe of the local sand control well plugging system are applied on the casing pipe of the wellbore system. The plugging process of the sand control well system is simulated by pumping a sand-laden slurry into the wellbore system. The plugging removal process is simulated by setting the plugging removal tool of plugging removal system through an oil tube in the wellbore system. The plugging removal effect of the plugging removal tool is analyzed and evaluated according to the reliable data measured by the pressure gauge, flowmeter, etc.

Simulation device and method for integrated evaluation experiment for sand control wellbore plugging and plugging removal

The invention relates to a device and a method to assist with the operation of an instrument by means of said device, the device and the method using leverage effects in order to calculate the data relative to any point of an instrument axis, instead of using low-accuracy sensors. Other improvements are also described that allow higher-quality usage performance for the operator, which reduces the risk of errors and simplifies the operations.
