Design Of The Algorithm Of Digital Drilling-parameters And Realization Of Monitoring And Control Functions

Drilling parameters instrument as an intergraded instrument is applied for monitoring drilling process and collecting the corresponded parameters which provide powerful evidence for scientific analysis and correct decision-making. My work is focused on design of crownblock anti-collision function and automatic-grouting function for a new type of Drilling parameters instrument.Meanwhile, based on the responsibility of data of drilling parameters, crownblock anti-collision system and automatic-grouting system are carried out. The main functions are tested. The results illustrated that this parameter has its unique merits such as avoiding the reinvestment of hardware, reduceing the re-development of software, promoting the utilization ratio of space in wellsite, and cutting the multi-cost of the three systems.In this thesis, the whole system structure and the epigynous machine software system are introduced. Given the characteristics and necessary data of both crownblock anti-collision function and automatic-grouting function, the analysis and decision-making function is divided into two parts: display part at front interface and calculation part at back-door interface. The former one is actualized in GUI(graphical user interface) software module, and the later one is done in data processing software module. Meanwhile, derivative parameters calculation and drilling condition judgement, the foundation of crownblock anti-collision disposal and automatic-grouting realization, is also done in the data processing software module, and derivative parameters calculation, drilling condition judgement, crownblock anti-collision algorithm processing and automatic-grouting algorithm processing is sealed in the class of CDataProcess, ready to be called by other program. In order to implement the command of epigynous machine system and actualize the function of crownblock anti-collision and automatic-grouting, the development of hardware control module is achieved, which takes use of relay to actualize sound & light alarm, braking control and drill pump manipulation. Besides, to meet customers'needs, the system accomplished automatic startup software module and dual redundant software module under both Linux environment and Windows environment by Shell script programming and API programming.
