Download Drilling Hydraulics For Mac 5.0

Calculation of both hydraulic horsepower and impact force mainly depends on calculating pressure drop across the bit. A major percentage of normal circulating pressures is lost by pumping through the nozzles when jet bits are used. Here you shall understand Hot to perform Oilfield Drilling Bit Hydraulics Calculations & download its calculator Excel.

The pressure loss is not frictional pressure but rather acceleration forces. Assumptions generally made are

Example On How To Calculate bit pressure drop, Hydraulic Horse Power And Impact Force

Calculate the drill bit pressure drop, hydraulic horsepower and impact force for the following set of conditions:

Mud weight = 14.5 Ib/gal

Flow rate = 300 gal/min

Jet sizes = three 12/32 in. jets

Solution:

1. Determine the nozzle area, AT:

AT = 3 x π /4 x (d)^2 = 0.331 in^2

2. Eq.3 is used to calculate the pressure drop at the bit:

PB= (300)^ 2 x 14.5 / ( 0.95^2 x 0.331 ^2 x 12028) = 1097 psi

3. Calculate the hydraulic horsepower expended at the bit from Eq.4

HHP = (1097 psi x 300 gal/min) / 1714 = 192 hp

4. The hydraulic impact force due to pressure loss through the drilling bit is computed from Eq.5

Fi = 0.01823 x (0.95) x (300) x ((14.5)(1,097))^(1/2) = 654 Ib

Ultimate Hydraulic / Mechanical Drilling Jar

The Ultimate Hydraulic/Mechanical Drilling Jar (UHMJ) is a double acting jar, designed to deliver hydraulic delay when jarring in the up direction, and mechanical release when jarring in the down direction.

Using proprietary new technology, Wenzel Downhole Tools has been able to dramatically increase the allowable overpull force. The UHMJ incorporates a latch mechanism to keep the jar locked in the neutral position and eliminate unexpected jarring while tripping or racking on the derrick.

  • The UHMJ is normally operated in the latched position to reduce unexpected jarring while drilling and eliminate movement between jar components, increasing service life.
  • The UHMJ operates with a simple up and down motion and is not affected by torque.
  • The spline drive and latch mechanism are enclosed in a single, sealed oil chamber without ports to the annulus. Such ports on other jars may fill with cuttings and restrict the down jar stroke.
  • The hydraulic delay mechanism is located in a separate chamber to prevent contamination and increase reliability.
  • With the latch mechanism in the latched position, the inner mandrel and outer housing act integrally, virtually eliminating seal and inner tool wear during normal drilling conditions. There is no need to extend or open the UHMJ before running in the hole.
  • Standard seals in the tool are effective to 250°F (120°C). The jar can be dressed with seals
    effective to 400°F (200°C) for hot hole environments, and 450°F (230°C) for extreme
    temperature environments. External sealing surfaces are tungsten carbide-coated to enhance
    wear and corrosion resistance
  • The UHMJ can be run in tension or in compression within the preset latch settings.

Jarring Up

  • Jarring up is achieved by applying sufficient overpull to overcome the latch setting, which initiates the hydraulic time delay. During the time delay, the overpull at surface can be adjusted to vary the impact force.
  • After impact, apply a down force sufficient to close jar and re-engage latch, then repeat the jarring cycle as required.

Jarring Down

  • Jarring down is achieved by applying sufficient downward force to overcome the latch setting and pump open force. At that point, the UHMJ will release and jar downward. After impact, pick up the work string to re-engage the mechanical latch then repeat the jarring cycle as required.
