Description

one

The device relates to information measuring systems used in various fields of science and technology, and can be used, in particular, to record technological and technical-economic indicators of B during the drilling of oil and gas plants.

According to the main author. No. 566540, a device is known which comprises a polling unit connected to a distributor, a comparison circuit and a memory unit, one of which is directly connected to one of the outputs of the distributor and to the register output, and the other through a comparison circuit the output of the registration unit is connected to the printing unit. In addition, an operation recognition unit and an OR element are inputted into the device, the inputs of which are connected to a clock pulse sensor and an operation recognition unit connected to the side of the poll. The output of the OR element is connected to the output of the distributor, the other output of which of the connectors to the one-room is from the inputs of the register, the other input of which is connected to the Burden sensor,

In any technological process, it is often observed that it is deviating from its normal flow, which is associated with disturbances in the technological sequence of operations, and the occurrence of emergency situations occurs. For example, when drilling kefgy gas before starting another drill or before lifting a tool, it is necessary to wash the well. Skipping this operation or another technological operation may be the cause of the accident. In the registration device using auth.

With the goal of eliminating this shortcoming, a pulse formaker and an additional memory block were added to the proposed device, a comparison circuit, a co-hor output connected to a registration unit, and inputs with an additional memory block output and a pulse generator 3 output. . The inputs of the latter are connected to the output of the operation recognition unit, the input of the polling unit and the output of the time sensor, which is connected to one of the inputs of the additional memory unit, the other input of which is connected to the corresponding input of the pulse former. The block diagram of the device is shown in the drawing. The device includes a polling unit 1 and an operation recognition unit 2 to which the output buses of the 3 sensors are connected. The polling unit 1 is connected to the comparison circuit 4 and the memory unit 5 connected to the comparison circuit 4 and the recording unit 6. The latter is connected to the printing unit 7. The time sensor 8 is connected to the register 9 connected to the distributor U and the register unit

rashga 6. The clock pulse sensor 11 is sewn by the first V-code of the AND 12 element to the distributor Yu, which is connected to the polling unit 1 and the recording unit 6. The second input of the OR element 12 is connected to the operation recognition unit 2 connected to the pulse shaper 13, the second and the third The inputs are connected respectively to the 3 sensor bus and the time sensor 8, and the output to the first input of the additional comparison circuit 15, the second input of which is connected to the output of the additional memory block 14.- The inputs of the latter are connected to the time sensor -8 and the buswater nnformash1i 16, comparison circuit output 15 is connected to the recording unit 6.

The operation of the device is reviewed. by the example of its use in the registration of technological parameters in the construction of oil and gas wells.

In the process of deepening wells, the sensor 11 at a certain time interval or penetration entails a clock pulse that activates through the element, OR 12 the distributor Yu, the Distributor connects one of the parameter sensors on bus 3 to the polling unit 1, where the measurement takes place, The data in the polling unit 1 and the memory unit 5 is compared in the comparison circuit 4, which outputs a signal to the unit, to register 6 for printing only if their values are not equal to the given discreteness. Then a second parameter sensor is polled and a comparison operation is repeated, and so on. After

parameter sensors and a time sensor 8, a signal is generated, in a format similar to that installed in the unit on bus 14 via bus 16. In this format contains the depth of the well, the code of the type of technological operation corresponding to this depth means the technological parameters. If any component of this, the format of the actual values deviates from those specified at the output 1 of the comparison circuit 15, to the input of which these values are supplied, the signal acting on the solution unit 6 appears. This changes the print color, for example. After the disappearance of the deviation or at the operator's signal, the device returns to the initial state.

Thus, in the registered data, the moment of occurrence of deviations in the course of the technological process is constantly noted, which allows the operator to quickly intervene in the process to restore the preset mode. In addition, in case of complications of analyzing the recorded information, it is possible to establish the cause of the complication.
