At present, the cost per ton of drilling has become a fashionable term for drill bit drawing; facing increasingly chaotic drilling environments and continuous drilling skills; major leading drill manufacturers in the United States have introduced unique new bit products; drill drawing and production Skills are developed rapidly and steadily.
US Hughes 0? Dead é”¼ ? ? ç”· ç”· çŽ‡ XL long life motor drilling drill bit; significantly improved drilling economy in the Gulf of Mexico and other high-cost drilling environment.
The drills offer significant improvements in seal reliability, cutting layout durability, and the ability to equip hydraulic systems; they allow longer downholes; and make drilling operators more determined to use them in longer directional sections. The new cones are well protected from drills and bottom mud packs when using water-based mud; they have ambition and maneuverability; and can be used in a variety of reaming equipment. All of these features make this drill a high-end drilling One of the most suitable drilling things in use.
The company conducted extensive analysis of on-site drilling data and examined a number of blunt drill bits to determine the associated conditions that would constrain the life of the drill/bearing. The improvements made on this basis included a new single-energy supply loop. Metal Seal Layout (SEMII); this layout can greatly improve the reliability of the bearing; especially in the high-speed motor drilling process. The new SEMII metal seal layout has a wider metal sealing surface; the progressive seal can reach 20%; The bearing also uses a proprietary wear-resistant appearance to reduce the coefficient of friction. Others; this seal layout has a number of seal shapes depicted from the head that also improves the sealing power.
In terms of cutting layout; there are three primary improvements that allow the MXL tri-cone bit to achieve a wider layout size; then more durability and higher penetration rates can be achieved in more applications.
These improvements include a new type of cemented carbide trademark; it can be used to improve wear resistance; to better apply to a variety of detailed drilling applications, modified tooth protection; this tooth can protect the gear steel data It is protected from the erosion of cuttings; it then ensures the integrity of the cutting layout; it does not contribute to the drilling speed of the drill bit.
In terms of the hydraulic layout of the drill bit; the MXL drill bit has several different hydraulic layouts that allow it to be optimized for a variety of detailed uses.
One is to standardize the hydraulic layout. This layout is to standardize the nozzle equipment; the drilling fluid is directed between the cones and toward the corner of the well wall.
The other is the No. 2 and No. 3 nozzle offset type. The primary policy of this type of nozzle is to remove the outer teeth of the cone and its adjacent areas and flush the opposite side of the cone together; the primary hydraulic energy will be collected in the cutting layout of the drill. on.
There is also a hydraulic layout that is multi-row clear. This layout removes multiple rows of teeth on the cone and can generate high turbulent energy at the bottom of the well.
The excellent function of this new drill has been proven on the spot; the cost savings from using this new drill bit are as high as $300,000. Based on the use in the Gulf of Mexico; one of these new drills has replaced 2~ 3 gauge steel tooth drills; double the footage during the drilling process. In another application; 3 of these drills with new skills replaced 5 conventional steel drill bits; improved ROP; reduced Number of drills.
