Description

Down-hole nearly drill bit multiparameter measuring device
Technical field
The engineering parameter that this utility model relates at the nearly drill bit in down-hole in petroleum-gas fiedl exploitation drilling process measures skill Art field, particularly relates to a kind of down-hole nearly drill bit multiparameter measuring device.
Background technology
Along with the development of petroleum exploration and development industry, deep-well, ultradeep well, multilateral well, big level of displacement Ratio shared by the Holes of Complicated Wells such as well increases year by year, and these Holes of Complicated Wells propose the newest challenge to drillng operation. Wherein, at the nearly drill bit in down-hole, measurement and the monitoring of engineering parameter are technology being badly in need of development.The work of nearly drill bit Journey parameter specifically includes that the pressure of the drill, moment of torsion, vibration (extensional vibration, oscillation crosswise and twisting vibration), drill string Interior pressure, annular pressure and annular space temperature etc..Engineering ginseng during oil, pneumatic drill well operations, at nearly drill bit Number is the key factor affecting drillng operation safety and drilling efficiency.Can supervise by measuring the pressure of the drill at nearly drill bit The reality surveying drill bit acquisition breaks the size of rock energy;Can by the moment of torsion and oscillation intensity measuring drilling tool at nearly drill bit To reflect the fatigue damage degree of drill string;The cleaning journey of well can be predicted by the variation tendency of pressure measuring value Degree and mud take the quality of lithology energy;The change of formation temperature gradient can be reflected by the change of measured temperature Change with well system temperature field.By the engineering parameter at the nearly drill bit in monitoring down-hole in real time, it is possible to obtain big The useful information of amount, has important engineering significance for prevention drilling complexity operating mode and drilling failure.
