The Anti-Interference Technology Of Oil Drilling

Drilling is a high investment, high risk project, with a large number of fuzziness, randomness and uncertainty. Therefore the anti interference technology in ensuring the safety of drilling plays a more and more important role.This article mention the disturbance of the oil drilling, oil drilling in the process of natural disturbance and new drilling equipment interference is analysised, and on the basis of theoretical analysis of the different interference signals were tested.According to various interfering signal causes and the test results of the disturbance signal, the current domestic for the more commonly used anti-interference methods is compared and analysised.And then put forward filter consisting mainly of comprehensive anti jamming technology.In this paper,we propose an improved FIR-IIR Filter method which can not only improve the SNR of the system,but also suppress the peak value the psd of the transmission signal with the invariable number. The problem degradation of SNR can be solved by by utilizing trimming Filter.In order to prove the practical applicability of the system, we compare the signal-to-cochannel interference component ratio, signal-to-Gaussian noise companent ratio, SN ratio and anti-interference characteristics, in the case where the communication system using the FIR-IIR filter with the system without filter.Finally, this article aims at the scene of the actual situation, puts forward corresponding anti jamming scheme. Practical results show that the proposed anti-interference technology solve the problems in the process of drilling for oil field interference effectively, and this technology improve the signal-to-noise ratio and Filtering accuracy of the system...
