In working condition.
Specifically, in order to realize that the power supply to measurement-while-drilling system optimizes management, it is necessary first to a set of measurement while drilling
The identifying system of system status.The maximally efficient state recognition of measurement-while-drilling system is exactly pressure, using pressure measxurement and
Monitoring, the Position Approximate of pit shaft at measurement-while-drilling system can be identified, may further determine whether to start entirely with brill
Measuring system.
Specific implementation process is as follows：
Firstly, it is necessary to by (offline) the startup pressure value for setting startup measurement-while-drilling system in ground, only surveyed when with brill
When wellbore environment pressure residing for amount system is more than or equal to default startup pressure, just measurement-while-drilling system is controlled to start.
In measurement-while-drilling system going down process, monitor its environmental pressure and be consistently less than startup pressure, then control with brill
Measuring system is constantly in resting state.Measurement-while-drilling system in a dormant state does not work, and does not expend and is deposited with brill power supply
The electric power of storage.
Measurement-while-drilling system it is neighbouring or reach shaft bottom when, monitor the wellbore environment pressure residing for measurement-while-drilling system
More than pressure value is started, then the supplying channels of measurement-while-drilling system are now opened, control measurement-while-drilling system is in running order,
Measurement-while-drilling system proceeds by the measurement and transmission of correlation.
After trip-out starts, slush pump stops, and when monitoring, the wellbore environment pressure residing for measurement-while-drilling system is once small
When pressure is started, make measurement-while-drilling system in a dormant state by turning off with the power supply for boring power supply (battery).
Using described in the present embodiment with bore method for managing power supply, to the power supply of whole measurement while drilling or logging system carry out
Optimum management, extend single and go into the well working time of measurement while drilling or logging system, while save the use of High Temperature Lithium Cell
Amount, reduce the use cost of measurement-while-drilling system.Therefore, according to the present embodiment with the system bored designed by method for managing power supply
, can be with the use of effectively save High Temperature Lithium Cell with the characteristics of stable performance, reliability is high.For example, more than 5000m
During deep drilling, every time the lower time bored and pulled out of hole may need more than 24 hours, if this time can allow except for
Circuit system beyond the module of detection pressure can then extend the usage time of battery more than 10% in a dormant state.
