| titleOfInvention | The determination method and device of formation pore pressure |
| abstract | A kind of determination method and device of formation pore pressure is the embodiment of the invention provides, wherein, the method includes：The mud flow rate parameter of Real-time Collection mud pump inlet, the mud flow rate parameter of back pressure pump intake and drilling fluid return flow；Mud flow rate parameter, the mud flow rate parameter of the back pressure pump intake and the drilling fluid return flow according to the mud pump inlet for gathering, calculate down-hole drilling fluids inlet flow rate and return the magnitude relationship between outflow；According to down-hole drilling fluids inlet flow rate and the magnitude relationship and formation condition information between outflow are returned, the difference of formation pore pressure and shaft bottom drilling well liquid columnpressure is calculated in real time；According to the formation pore pressure and the difference and known shaft bottom drilling well head of liquid of shaft bottom drilling well liquid columnpressure, formation pore pressure is calculated in real time.The program can improve the degree of accuracy of formation pore pressure result of calculation. |
