When drilling diamond segments for sandstones in soft and medium-hard formations, they have the advantages of fast speed, large footage, long life, stable work, fewer downhole accidents, and good well quality. The diamond segment for sandstone not only has a long use time but also can be reused. The diamond segment for sandstone returned to the factory for repair has the same effect as the factory diamond segment for sandstone, which can save a lot of drilling costs. Let me introduce the diamond segment for sandstone. Here are some answers.
Here is that the content list:

Advantages of diamond segments for sandstone.
Rock breaking mechanism of diamond segment for sandstone.
The quality of the diamond segment for sandstone and whether the drill bit-type of the diamond segment for sandstone is compatible with the formation lithology plays an important role in accelerating the drilling speed and increasing the footage of a single bit. Drilling an oil and gas well with a diamond segment for sandstones generally requires multiple drill bits of different sizes. When drilling the upper stratum, a larger diameter drill bit is used. Because the stratum drilled by the drill bit is relatively soft, a single drill bit has large footage and time of use. Short, one drill bit can generally be reused for several wells. Diamond segments for sandstone should use smaller diameter drill bits when drilling the lower stratum. Because the formation is hard and the footage of a single drill bit is small, multiple drill bits are generally used. The drilling footage of a new drill bit mainly depends on the size and type of the drill bit, the softness and hardness of the formation, and the coordination of drilling parameters. Generally speaking, the smaller the size of the drill bit and the harder the formation, the smaller the footage; the larger the size of the drill bit and the softer the formation, the more the drill footage will be.
First, the force balance design of the diamond segment for sandstone enables the diamond segment for sandstone to have good guidance, which is suitable for the application of downhole motors in directional drilling and has relatively small radial vibration. Second, the highly aggressive design of the diamond segment for sandstone enables the drill bit to obtain a high ROP.
In some brittle rocks, such as sandstone, limestone, etc., the diamond particles on the drill bit of the diamond segment for sandstone are under the simultaneous action of the WOB torque, and the volume of the broken rock is much larger than the intake and rotation volume of the diamond particles. The braking effect of the diamond segment for sandstone is related to lithology and external factors that affect lithologies, such as pressure, temperature, and formation fluid properties. The weight on the bit of the diamond segment for sandstone is an important influencing factor.
