Embodiment 1

[0100] Embodiment 1. The present invention is applied to the construction site of drilling with sensors installed for detection, such as supporting Wenchuan Branch Drilling WFSD-4 hole drilling sensor data, the rotary speed of the scene, hook height, hook load, standpipe Sensor parameters such as pressure, load-bearing sensor, current, impulse speed, flow rate, temperature, density, and mud pool volume are converted from analog signals of sensors to digital signals through a USB data acquisition card and collected to the drilling site. Due to the poor conditions of the drilling site and high-load production, it is necessary to use a wireless transmitting station to send the field data to a field base with a network and better conditions. For example, a wireless receiving station is used to receive the transmitted sensor signals within 20km. Then through the calculation, analysis and processing of the LabVIEW software platform, the secondary conversion data such as drilling pres...

Abstract

The invention provides an intelligent drilling system based on LabVIEW and an application thereof. The application comprises the following steps of acquiring various data during drilling by using a multi-path data sensor, transmitting the acquired various data to a data acquisition card, transmitting the data in the data acquisition card to field equipment for display, and transmitting the data toa field base outside 20km through a radio station, processing related data and generating two-dimensional and three-dimensional images through LabVIEW software installed on the field base, utilizingthreshold judgment, data fusion and a neural network to realize preliminary diagnosis and prediction of accidents in real time, transmitting the preliminary diagnosis and prediction to a large-scale base with more complete equipment, completing multiple expert consultation, and finally sending consultation results to the site for efficiently and professionally completing drilling engineering. According to the intelligent drilling system based on LabVIEW and the application thereof, the identification of four complex working conditions such as well kick, well leakage, core blockage, and in-place signaling of a coring tool and the timely diagnosis of four accidents such as drill jamming, drill burying, drill burning and drill tool fracture can be realized.

Description

technical field [0001] The present invention is applied to the working condition identification and accident diagnosis of drilling rigs in scientific drilling or deep drilling, which is convenient, quick and has strong applicability, and especially relates to a method applied to complex working conditions and accident diagnosis. Background technique [0002] The existing working condition identification is mainly suitable for oil drilling, and the use of Beidou transmission is costly and cannot be applied to geological drilling; in geological drilling, the working condition identification is not perfect, the application rate is extremely low, and there is no accident diagnosis function. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned defects in the prior art, and to provide an intelligent drilling system based on LabVIEW, which can realize the recognition of four complex working conditions, such as well kick, lost circ...
