Description

Technical Field

[0001] The present invention relates to the field of drilling measurement technology, and in particular to a drilling measurement system. Background Art

[0002] Measurement While Drilling (MWD) refers to the continuous detection of information about the borehole or drill bit while the drilling rig is drilling. This is achieved by tracking and guiding instruments. Therefore, tracking and guiding instruments are essential measurement equipment for horizontal directional drilling rig construction. Logging While Drilling (LWD) is a measurement instrument used in MWD (Measure While Drilling). The gyroscope is a mechanical device whose main part is a rotor that rotates at an extremely high angular velocity about the rotating axis and is mounted in a bracket. An inner ring frame is added to the central axis of the rotor, so that the gyroscope can move freely around two axes in a plane. Then, an outer ring frame is added to the outer ring frame. This gyroscope has two balancing rings and can move freely around three axes in a plane, forming a complete space gyroscope. Gyroscopes are also used in drilling measurement technology.

[0003] The current drilling measurement system's operational modularization is not perfect enough, and the controllability of the system operation is affected. The key to gyro measurement lies in the accuracy and timeliness of measurement data, while the conventional system structure is simple. Especially when used in high-temperature environments, the gyroscope has insufficient working capacity in high-temperature environments, and its weak subdivision function makes it difficult to detect abnormal situations in a timely manner, resulting in measurement accuracy that cannot meet engineering requirements.

[0100] The present invention can use the MEMS gyroscope ADXRS645. The rated operating temperature of the ±2,000° / second ADXRS645 MEMS gyroscope is 175 degrees Celsius. The ADXRS645 MEMS (micro-electromechanical system) gyroscope has excellent vibration resistance and a minimum rotation measurement range of ±2,000° / second. These two characteristics are crucial for drilling tools operating in harsh high-temperature environments. The precise angular rotation detection capability can detect the difference between the drill bit rotation and the drill bit drive motor, thereby effectively preventing damage to the drill string. With the help of the ADXRS645, the normal operation of the drill string can be ensured, thereby allowing drilling equipment operators in the oil and gas industry to extend equipment life and reduce costly downtime.

[0101] The ADXRS645 is part of a portfolio of precision, high-temperature components designed for drilling applications. The family includes the ADXL206 ±5g precision MEMS accelerometer, the AD8229 ultralow-noise instrumentation amplifier, the ADR225 2.5V bandgap voltage reference, and the AD8634 dual-channel amplifier with rail-to-rail outputs. All of these components operate at temperatures of 175°C and above.

[0102] The ADXRS645 operates from a single 5V low-voltage power supply and utilizes a unique ceramic vertical mount package that allows for secure mounting on a PCB, eliminating the need for an orthogonal-mount daughter card. The ADXRS645 is a high-performance angular rate sensor with excellent vibration resistance and can be used in high-temperature environments.

[0103] This gyro is housed in a vertically mounted ceramic package, suitable for pitch or roll rate response, and features a wide operating temperature range of -40°C to +175°C; long life: guaranteed for 1000 hours (at TA = 175°C); high vibration suppression characteristics over a wide frequency range; shock resistance: 10,000g; output ratiometric to the reference power supply; single 5V power supply; self-test based on digital commands; and temperature sensor output.

[0104] In the scheme of the present invention, the drilling process can be divided into three parts according to the construction procedures: pre-drilling, drilling and completion. Pre-drilling mainly refers to well site measurement, design, construction, foundation, as well as moving and installing equipment, commissioning, etc.; drilling is the beginning of construction, including the acceptance of each opening, such as the first opening, the second opening, and drilling operations, that is, dividing the footage into sections and completing them according to the construction design requirements of the client; completion mainly refers to logging, analysis, formation interpretation, oil layer positioning, casing running, cementing and post-setting pressure testing after the footage is completed, and finally leveling the well site and handing over the well.

[0105] In the scheme of the present invention, the parameters that need to be accurately measured during drilling are mainly divided into two categories. The first is drilling technology, such as drilling pressure, rotation speed, pump pressure and displacement, which are the four most important parameters. After drilling is completed, the well diameter, well inclination, azimuth, dogleg degree, well temperature, and other data required by the client must be obtained during logging; the second is drilling fluid, such as density, viscosity, data measured by a six-speed rotary meter, slope content, water loss, mud cake, friction coefficient, high temperature and high pressure water loss, Ph value, sand content, etc.
