Oil well bore track plotting device and method

Abstract

An oil well well trajectory surveying and mapping device and method relate to oil well surveying and mapping. The surveying and mapping device is equipped with an oil well trajectory sensor module, a data processing module, a remote transmission module, a local interaction module, a remote server, a three-dimensional data image rendering module and a client web browser. Surveying and mapping methods: 1) Put the sensor module into the oil well to be tested; 2) Measure the inclination angle, high side angle and azimuth angle at the initial moment in a static state; 3) Make the sensor module move continuously along the wellbore trajectory of the oil well; 4 ) Determine the attitude of the sensor module at any time according to the above method of continuously measuring the attitude; 5) Determine the oil well depth at the corresponding time by double integrating the z-axis acceleration value of the three-axis accelerometer; 6) Repeat steps 3) to 5) , to obtain the attitude of the sensor module at any time and the corresponding oil well depth, and finally determine the well trajectory of the oil well. Real-time measurement of oil well trajectory, short testing time and low cost.

Description

technical field [0001] The present invention relates to oil well surveying and mapping, in particular to an oil well wellbore trajectory surveying and mapping device and method. Background technique [0002] With the rapid development of my country's economy, my country's demand for crude oil and refined oil has increased substantially, and oil resources have become increasingly depleted. Accurate mapping of oil well trajectories has become more and more important. During the drilling process, it is necessary to know the actual trajectory of the drilled wellbore to control the drilling trend. After the oil well is completed, it is also necessary to judge whether the wellbore trajectory is within the preset range; for old oil wells, it is necessary to accurately measure the wellbore trajectory , in order to realize its secondary development. The wellbore trajectory of the oil well can be mapped by measuring the spatial position information of the wellbore. The position of th...

Problems solved by technology

The traditional method of using a magnetic orientation instrument cannot be measured due to the influence of the magnetic field of the casing; the micromachined gyroscope is designed with MEMS technology, has no rotating parts, does not require bearings, and has a very small size, light weight, and With the advantages of low cost, it has been applied in civilian markets such as automotive safety systems, game machine motion control, smart phones, and industrial control.
