In water well drilling operations, are you often troubled by excessive bit wear and poor wellbore stability? When operating the UNIQUE water well drilling rig, measuring the performance of drilling fluid during the tripping process is the key to solving these problems. As a professional manufacturer of water well drilling rigs, UNIQUE is well aware of the decisive role of drilling fluid performance in operational efficiency. This article will detail the necessity and practical steps of measuring drilling fluid performance during the tripping process.

Core Value of Measuring Drilling Fluid Performance in UNIQUE Rig Operations

The UNIQUE water well drilling rig is renowned in the industry for its efficient and stable performance, and drilling fluid, as the "blood" of the rig, directly affects the performance of the equipment.

Firstly, real-time monitoring can promptly detect abnormalities in the drilling fluid. When the UNIQUE water well drilling rig operates in complex formations, a sudden increase in drilling fluid density may indicate the invasion of formation fluids, while abnormal viscosity suggests a decline in cuttings carrying capacity. By measuring, parameters can be quickly adjusted to avoid affecting the drilling efficiency of the UNIQUE water well drilling rig.

Secondly, accident prevention is a key role of measurement. The precision components of the UNIQUE water well drilling rig have high requirements for the cleanliness of the drilling fluid. Excessive sand content will aggravate the wear of bits and pump bodies. In 2024, when a mining area used the UNIQUE water well drilling rig, a blowout occurred because the drilling fluid performance was not monitored. Later tests found that the density had deviated from the standard value by 15%, which highlights the importance of measurement.

Standard Procedures for Measuring Drilling Fluid Performance During Tripping (Adapted for UNIQUE Rig)

Sample Collection Specifications

• Time: 30 minutes before each trip out and immediately after tripping in

• Location: Middle part of the dedicated drilling fluid circulation tank of the UNIQUE water well drilling rig

• Tool: Use the UNIQUE matching sampler to avoid mixing with bottom sediments

Measurement of Key Indicators

• Density: Use the digital density meter recommended by UNIQUE with an accuracy of ±0.01g/cm³, which is calibrated in linkage with the pressure control system of the UNIQUE water well drilling rig

• Viscosity: Use a six-speed rotational viscometer to measure the readings at 600r/min and 300r/min, and calculate the dynamic shear force value

• Sand Content: Use a centrifugal sand content tester. The UNIQUE water well drilling righttps://www.uniquedrilling-tech.com/products-item/water-drilling-rig/ requires the sand content to be controlled within 0.5%

Data Recording and Analysis

It is recommended to use the UNIQUE intelligent drilling management system, which automatically records measurement data and generates trend curves. It will automatically alarm when the value exceeds the preset threshold (such as density > 1.2g/cm³).

Supporting Advantages of UNIQUE Drilling Rig

The new generation of UNIQUE water well drilling rigs is equipped with an integrated drilling fluid detection interface, which can be directly connected to detection equipment to realize real-time data transmission. Combined with the exclusive drilling fluid treatment scheme, it can automatically adjust the injection amount of additives according to the measurement results, increasing drilling efficiency by more than 20%.

Correct measurement of drilling fluid performance is the premise for the UNIQUE water well drilling rig to exert its best performance. Following the above procedures can not only ensure operational safety but also extend the service life of the equipment.
