Due to the problem of stratum or instrument itself in drilling and coring delivery process, very easily there is the stifled heart, fall the heart, the problem such as drilling fluid erosion, whether rock core enters cylinder, enter cylinder whether smoothly, entering the problems such as whether a rock core drops in trip-out process all can only rely on experience to judge at present, there is larger error and subjectivity, the coring operation easily made the mistake is constructed, and affects core effect and efficiency.
Summary of the invention:
The technical problem to be solved in the present invention is to provide a kind of drilling and coring delivery real-time detecting system, this system achieves whether detect by the rock core length measured in real time in coring inner drum the process of coring smooth, thus core construction and the operation under instructing complex situations, core effective, improve efficiency of coring, easy and simple to handle, dependable performance.Overcoming existing drilling and coring delivery situation can only rely on experience to judge, and there is larger error and subjectivity, the deficiency of the coring operation easily made the mistake construction.
The technical solution used in the present invention is: a kind of drilling and coring delivery real-time detecting system, is made up of data measurin system, data transmission system data interpretation system of unifying; Data measurin system is made up of coring inner drum, magnetic detector and pulse producer I, coring inner drum is axially all provided with a magnetic every certain spacing, magnetic detector is connected with pulse producer I, and magnetic detector and pulse producer I are placed in coring inner drum; Data transmission system is made up of pulse receiver I, signal converter I, pulse producer II and pulse receiver II, pulse receiver I, signal converter I, pulse producer II connect in turn, pulse receiver I, signal converter I, pulse producer II are placed in coring inner drum upper end, pulse receiver I can the pulse signal that sends of received pulse generator I, pulse receiver II is placed in ground, and pulse receiver II can the pulse signal that sends of received pulse generator II; Data interpretation system is made up of signal converter II and data terminal, and signal converter II is connected with data terminal, and pulse receiver II is connected with signal converter II by cable.
The invention has the beneficial effects as follows: whether the present invention detects by the rock core length measured in real time in coring inner drum the process of coring smooth, thus core construction and the operation under instructing complex situations, core effective, improve efficiency of coring, easy and simple to handle, dependable performance.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of coring inner drum.
Embodiment:
As shown in Figure 1 and Figure 2, a kind of drilling and coring delivery real-time detecting system, is made up of data measurin system, data transmission system data interpretation system of unifying; Data measurin system major function is the length distinguishing rock core in coring inner drum, data measurin system mainly adopts magnetic detecting principle, shaft bottom data are mainly transferred to ground by data transmission system, and data interpretation system is mainly explained the data analysis of shaft bottom transmission.Data measurin system is made up of coring inner drum 1, magnetic detector 2 and pulse producer I 3, coring inner drum 1 is axially all provided with a magnetic every certain spacing, magnetic detector 2 is connected with pulse producer I 3, and magnetic detector 2 and pulse producer I 3 are placed in coring inner drum 1; Data transmission system is made up of pulse receiver I 4, signal converter I 5, pulse producer II 6 and pulse receiver II 7, pulse receiver I 4, signal converter I 5, pulse producer II 6 connect in turn, pulse receiver I 4, signal converter I 5, pulse producer II 6 are placed in coring inner drum 1 upper end, pulse receiver I 4 can the pulse signal that sends of received pulse generator I 3, pulse receiver II 7 is placed in ground, and pulse receiver II 7 can the pulse signal that sends of received pulse generator II 6; Data interpretation system is made up of signal converter II 8 and data terminal 9, and signal converter II 8 is connected with data terminal 9, and pulse receiver II 7 is connected with signal converter II 8 by cable.
The effect of magnetic detector 2 is changes of magnetic on detection coring inner drum 1.Pulse producer I 3 is used to the magnetic signal that magnetic detector 2 detects to be converted to pulse model, detects magnetic with regard to transponder pulse, does not nonmagneticly launch.Pulse receiver I 4 is used to the pulse model that received pulse generator I 3 sends.Signal converter I 5 is used to pulse signal to be converted to electric signal, and have pulse to be 1, no pulse is 0.Pulse producer II 6 is used to convert electrical signals to pulse signal.Pulse receiver II 7 is used to the pulse model that received pulse generator II 6 sends.Signal converter II 8 is that pulse signal is converted to electric signal, and have pulse to be 1, no pulse is 0.Data terminal 9 is used to explain electric signal, determines that rock core enters the length of cylinder in real time.
Cardinal principle of the present invention is that the power by measuring magnetic on coring inner drum 1 differentiates the length of rock core at coring inner drum 1.Its detection process is: coring inner drum 1 has a magnetic every certain spacing, magnetic detector 2 and pulse producer I 3 are in the bottom of core drilling anteposition in coring inner drum 1, rock core enters in a process, promotion magnetic detector 2 and pulse producer I 3 are advanced in inner core, when magnetic detector 2 arrives magnetic position, magnetic is the strongest, this magnetic strong and weak signals is converted to electric signal, then launched by impulse sender, arrive a magnetic point, launch pulsatile once, on ground by detecting the quantity of shaft bottom pulse, the distance of magnetic detector 2 and pulse producer I 3 movement in coring inner drum 1 can be known, thus determine that rock core enters the length of cylinder in real time.
Be understandable that, above about specific descriptions of the present invention, the technical scheme described by the embodiment of the present invention is only not limited to for illustration of the present invention, those of ordinary skill in the art is to be understood that, still can modify to the present invention or equivalent replacement, to reach identical technique effect; Needs are used, all within protection scope of the present invention as long as meet.
