Embodiment Construction

[0022] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0023] First refer to figure 1 , figure 1 A drilling rig equipped with a tracer 11 according to the invention is shown. figure 2 and image 3 The tracer 11 is described in further detail.

[0024] First refer to image 3 , image 3 The structure of the tracer 11 is shown.

[0025] The tracer 11 is a spherical structure with a spherical package holder 27 ( image 3 Not marked in ), used to support and fix the remaining parts of the tracer 11. The material of the packaging bracket 27 can be stainless steel. The spherical package holder 27 includes two parts, an upper hemisphere 31 and a lower hemisphere 32 . The upper hemisphere 31 and the lower hemisphere 32 are connected by threads, and the connection can be sealed with fluorine rubber or silicon rubber ring. The inside of the ball can be filled with silicone oil to ensure the pressure balance between...

Abstract

The invention provides a tracer, which belongs to the field of oil drilling. The tracer includes: a spherical packaging bracket; a pressure sensor fixed on the bracket for measuring external pressure; a circuit board fixed inside the bracket, on which a temperature sensor and data processing components are arranged; a communication interface fixed on the bracket , wherein the measurement results of the pressure sensor and the temperature sensor are transmitted to the data processing element, and the data processing element stores the obtained result and transmits it through the communication interface. The present invention also proposes a drilling equipment including the tracer, wherein the tracer can move with the drilling fluid in the fluid passage in the drill string, and return to the ground together with the drilling fluid after passing through the water hole and annular space of the drill bit. The invention also proposes a data acquisition method for the borehole through the drilling equipment. According to the tracer, equipment and method of the present invention, the parameters of the whole wellbore can be collected in real time, which makes up for the shortcomings of the prior art.

Description

technical field [0001] The invention relates to a tracer and belongs to the field of petroleum drilling. The invention also relates to a drilling device comprising the tracer and a method of using the drilling device. Background technique [0002] Temperature and pressure are two important basic data in drilling engineering. According to the temperature data, the gradient of the temperature in the wellbore increases with the depth, which can reflect the changes of the fluid characteristics of the drilling fluid and the stability of the wellbore wall to a certain extent. Pressure data can provide a basis for optimizing drilling fluid density and circulation equivalent, selecting the best casing depth, improving drilling efficiency, identifying oil and gas layers, and reducing operational risks and drilling costs. Real-time monitoring of the temperature and pressure of the entire wellbore, and the establishment of temperature and pressure profiles measured while drilling are...
