Construction data acquisition and processing system of horizontal directional drilling

At present, the data in horizontal directional drilling relies on manual recording over a long period of time, in which personal error and missing record are likely to occur, thus the data recorded can not refect the operation condition directly and guide the following drilling scientifcally and effciently. Data acquisition and processing system of horizontal directional drilling uses pressure transmitter to acquire the operation data like reaming torque, tension, mud pressure and so on in real-time, and process the data to fnd out the maximum torque, maximum tension, effective reaming time of each drill pipe, and plot the data into comparison curves to refect drilling operation condition of directional drilling directly, and help scientifc prediction of the potential problems in the following drilling, and thus the workout of preventive measures in advance. The application of this system can reduce the risks of operation and improve working effciency.
