The specific embodiment
Be described further this use is novel below in conjunction with accompanying drawing:
By Fig. 1 and shown in Figure 2, this multifunctional drilling fluid intelligent controller is through the flow velocity of drilling fluid in the electromagnetic induction principle measuring tube; Thereby calculate flow value, include oral instructions sensor 2 and outlet sensor 4, in inlet sensor 2 and the outlet sensor 4 positive and negative electrode a, b are arranged; Be data collecting system, the electrode structure form adopts outside plug type to contain the molybdenum stainless steel electrode, its tool superpower wear-resistant property; Wherein, Positive and negative electrode in the said inlet sensor 2 places in the drilling fluid inlet duct 1, and the positive and negative electrode of outlet in the sensor 4 places in the drilling fluid outlet conduit 3, and the positive and negative electrode in the described inlet sensor 2 is connected with monitoring host computer 5 through data line respectively with positive and negative electrode in exporting sensor 4; Monitoring host computer 5 is connected with display 6, and monitoring host computer 5 places in the driller house with display 6.
Above-mentioned monitoring host computer is a data handling system, comprising: power module is used to provide the operating voltage of I/O processor, arm processor and LCD; I/O processor, the data-signal that positive and negative electrode a, b are gathered carries out processing and amplifying; Arm processor leaches the signal after amplifying disturbing wave and is formed with the data-signal of effect through overcorrect, exports data to display then; Display apparatus module is used for data-signal is presented at touch panel; Memory control is single, is used for the playback of data processed signal storage, and is as shown in Figure 2.
And described I/O processor and arm processor are provided by Motorola Inc., and arm processor comprises: the A/D sample circuit, filter clutter, and gather flow waves; Excitation control CPU brings up to 85 hertz to excitation frequency, increases the flow velocity point of gathering; Three value wave height are field circuit frequently, is used for zero correction, to overcome the unstability that pulsating flow forms.Because the mobile particularity of drilling fluid; Solving the pulsating flow problem and become the most important thing, if use traditional low-frequency square-wave excitation mode, is to show high flow rate and low flow velocity and variable quantity from low to high really; So the multifunctional drilling fluid intelligent controller main frame of the utility model adopts the high frequency excitation mode; Bring up to 85 hertz to excitation frequency, just per second is gathered 85 flow velocity points, is 14 times of traditional approach.Though obtained the accurate flow under the pulsating flow state accurately through the high frequency excitation; But the high frequency excitation also has negative effect simultaneously; That is exactly electrical noise and the stability that shows under the pulsating flow state, and monitoring host computer has added noise reduction process and three value ripple excitations again in circuit, just between each positive wave negative wave, increased the zero correction function; 170 zero point alignments in the middle of 85 signals collecting, have been increased, the unstability that has overcome pulsating flow formation of success.
Data handling system is carried out the data that collect processing such as filtering, noise reduction, forms flow number accurately, and shows through the display in the driller house, makes operating personnel in time grasp drilling parameter.
This multifunctional drilling fluid intelligent controller can be monitored the numerical value of entry and exit mud flow rate in real time, has warning function simultaneously.In wellbore construction, through the difference of contrast entry and exit mud flow rate, whether anticipation has the generation of overflow or leakage fast, thereby makes a response as early as possible, avoids producing serious adverse consequences; Through the data that arrive of inlet sensor acquisition, can accurately monitor the efficiency of pump of borehole pump, simultaneously through the reduction value of contrast entry and exit mud flow rate; Judge whether operate as normal of borehole pump; In time overhaul, avoid low discharge capacity to creep into, prevent drilling failure.
