Multi-point selector and method for electronic inclinometer

Abstract

The invention relates to a multi-point point selection device and method of an electronic clinometer. The multi-point point selection device can be matched with the electronic clinometer to finish functions including self inspection of an instrument, setting of parameters, determination of measurement time of each measurement depth of a collection point, data receiving and the like. The multi-point point selection device can be used for multi-point measurement in a drilling process of petroleum drilling; acquisition time of the collection point of each measurement depth is automatically recorded by utilizing the multi-point point selection device; and after drilling is finished, acquired data of the electronic clinometer is intelligently selected through the multi-point point selection device and clock errors are eliminated automatically and invalid data are automatically eliminated. The product provided by the invention is low in price and simple and convenient to operate; data exchange between the product and the electronic clinometer adopts a wireless transmission manner and a cable is not used; and meanwhile, the problems of great working amount, high fault rate and the like, caused by manual point selection and manual recording, are eliminated, and the working efficiency and the success rate of measurement are improved.

Description

technical field [0001] The invention relates to a multi-point selector and a method, belonging to the field of petroleum drilling, in particular to a multi-point selector and a method for an electronic inclinometer. Background technique [0002] Multi-point measurement is the technical abbreviation of drilling trajectory measurement through electronic inclinometer during oil drilling. Among the known technologies, the multi-point measurement technology has long been recognized by people. In the practical application of multi-point measurement technology, manual records are usually used to obtain the measurement time and measurement depth of each measurement point at each measurement depth. Since the drilling time is usually more than 6 hours, the disadvantages of using manual recording method are: firstly, a special person is required to operate, and secondly, after receiving the data, it is necessary to select and collect from a large number of measurement data according t...

AI Technical Summary

Problems solved by technology

Since the drilling time is usually more than 6 hours, the disadvantages of using manual recording method are: firstly, a special person is required to operate, and secondly, after receiving the data, it is necessary to select and collect from a large number of measurement data according to the recorded information through manual search. Effective measurement data requires a large workload and is prone to errors. The third is that the clock of the electronic inclinometer and the timing clock also have deviations, resulting in errors in recording time, resulting in wrong point selection
