Description

one

The device relates to information measuring systems and is used, in particular, to record technological and technical and economic indicators in the process of drilling oil and gas wells.

A device for recording information is known, which contains a polling unit connected to a distributor, a comparison circuit and a memory unit, one output of which is directly and the other is connected to a registration unit connected to one of the distributor outputs and to the register output, and the output the registration unit is connected to the printing unit, and a clock pulse sensor.

In the case of using a known device for recording information in the drilling process, it is idle for a significant portion of the time. Information on the duration of operations other than “drilling” operations is important for analyzing the entire complex of well construction works.

The purpose of the invention is to register not only the technological parameters of any process, but also the registration of the time of all types of work performed within the pauses, i.e., the expansion of the functional capabilities of the device.

This is achieved by introducing an operation detection unit and an OR element whose inputs are connected to a clock pulse sensor and to an operation recognition unit connected to a polling unit, and an OR output output to the distributor, another output which is connected to one of the inputs of the register, the other input of which is connected to the time sensor.

The drawing shows a block diagram of the proposed device.

The device contains blocks 1 and 2 of polling and recognition of operations to which the output buses of 3 sensors are connected. The polling unit 1 is connected to a comparison circuit 4 and a memory unit 5, which is connected to the comparison circuit 4 and the registration unit 6 associated with the printing unit 7. The time sensor 8 is connected to a register 9 connected to the distributor 10 and the registration unit 6. The clock pulse sensor 11 and the operation recognition unit 2 are connected via the element OR 12 to the distributor 10, which is associated with the polling and registration blocks 1 and 6.

The operation of the device is considered on the example of its use for recording technological and technical-economic information in the process of building oil and gas wells. When drilling in the process of deepening the well sensor 11 after a certain interval

penetration produces a clock pulse, which includes the distributor 10 through the element “OR 12”. The distributor connects one of the parameter sensors (not shown in the drawing) to the polling unit 1, where the measurement takes place. The contents of the register and memory block 5 are compared in comparison circuit 4, which outputs a signal to registration block 6 for printing the contents of the parameter register only if its contents and the contents of memory block 5 are not equal to the specified resolution.

Next, a second parameter is polled, a comparison operation is repeated, and so on. After all parameters are polled, the information recorder comes to its original state and waits for the next step: its clock pulse from the discrete penetration sensor. When changing the drilling operation (for example, drilling is stopped and the tool is changed to change the bit), the operation recognition unit using information from the parameter sensors (flow, pressure, weight, penetration, etc.) recognizes the tool lifting operation and issues a signal to recording the drilling time of an incomplete penetration under the address of an incomplete penetration interval. After the registration is made, the time sensor 8 is turned on to measure the duration of the bit change operation.

With the end of the "bit change" operation, the operation recognition block issues a signal to print the contents of register 9, i.e., the time of the "bit change" operation, to reset the register to zero state and to measure the duration of the next operation, for example, "flush," is printed.

At the end of the flushing operation, drilling begins, the operation recognition unit issues a print signal for the flushing operation duration, and the information recording device waits for the next clock pulse from the flow sensors, with which the device operates according to the above scheme.

Thus, the proposed device registers, along with technological and technical and economic information in the course of drilling, the duration of the entire complex of operations of the construction process of oil and gas wells.
