Drilling engineering parameter state detecting method

Abstract

The invention discloses a drilling engineering parameter state detecting method. The drilling engineering parameter state detecting method comprises the following steps of (S101) acquiring sampling data of drilling engineering parameters at current time; (S102) judging whether the sampling data at the current time exceeds a preset top and bottom limitation threshold value, determining that the sampling data at the current time are abnormal and carrying out the step (S103) if the sampling data at the current time exceed the preset top and bottom limitation threshold value, and determining that the sampling data at the current time is normal and carrying out the step (S104) if the sampling data at the current time do not exceed the preset top and bottom limitation threshold value; (S103) judging sampling data at preceding n times are abnormal or not, determining that drilling engineering parameters are abnormal if the sampling data at the preceding n times are abnormal, and carrying out the step (S104) if the sampling data at the preceding n times are not abnormal; and (S104) judging the number of abnormal sampling data at the current time and preceding m times reaches k or not, determining that drilling engineering parameters are abnormal if the number of the abnormal sampling data at the current time and the preceding m times reaches k, and determining that the drilling engineering parameters are normal if the number of the abnormal sampling data at the current time and the preceding m times does not reach k. In the above-mentioned steps, m, k and n are positive integers, m is greater than k, and k is greater than n. By the drilling engineering parameter state detecting method, instantaneity and accuracy of judgment results can be guaranteed, and field engineers can be warned for the first time if underground conditions are complicated.

AI Technical Summary

Benefits of technology

This new technology has several technical benefits that can help make it better than previous technologies for certain applications such as communication systems.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the accuracy and timeliness with which petrolic well boreers operate while being drilled through various types of rocks such as shale (shake) sands, clay mineral deposits, carbonate sediments, limestone, dolostones, etc., without having direct observation from inside them. Current methods cannot provide accurate results at all times due to factors like environmental conditions and equipment limitations.
