Abstract


The development of deep-sea oil commonly used semi-submersible offshore platform or floating drilling rigs and other floating drilling unit for drilling operations. Due to the role of the waves, drilling platforms will produce the heave movement, and promote the drill string movement, resulting in the WOB instability, shorten the service life of the drill bit, and even forced to shut down, increasing the cost of drilling. In order to better study the heave compensation system and the study of the energy system, it is necessary to carry out the experimental research of the heave compensation system. In order to better test rig drill string heave compensation has been established to study the three-dimensional model of the test rig into the system dynamics analysis software ADAMS, after reasonable merger of the fixing member, delete the simulation useless member, and add the appropriate deputy campaign, the establishment of a virtual prototype model of drill string heave compensation test bench. Combined with the principle of control of the semi-active compensating valve-regulated, in the establishment of the hydraulic system of FIG. ADAMS, where the parameters are determined and based on the structural parameters of the test station; test bench according to the test procedure control parameters, to determine the parameters of the various hydraulic components, simulation, comparison of simulation and experimental results to determine the correctness of virtual prototype model of the test rig, and in this context, the factors affecting the passive compensation effect, such as compensation cylinder volume of the accumulator, air bag pressure, load cylinder accumulator volume of air bag pressure passive compensation simulation to determine its impact on the efficiency of passive compensation compensation effect and compensation; semi-active compensation to determine various parameters such as compensation cylinder volume of the accumulator, airbag pressure the load cylinder volume of the accumulator, the airbag pressure, the flow rate of the metering pump, hydraulic valve control function, the proportional coefficient of the compensation effect and compensation efficiency; identified by each of the above parameters change the impact on energy consumption of the system. for the test bed control the selection of parameters to provide a reference; simulation model, the actual test bench test conditions such as drill pipe breaks off, the load cylinder accumulator fault conditions, by quantifying The expression of identified damage to the test bench in the relevant conditions. In the semi-active compensated pump control valve control simulation, compares the simulation model was validated using experimental curve and the simulation curve, and the use of test data to make graphs were compared with two control modes.
