| Summary: | This report gives the account on the dissertation of the final year project report title
"Optimization of Drilling Hydraulics in Vertical Hole" assigned to the student as one of
the courses requirement by the Universiti Teknologi PETRONAS before his graduation.
The final year project given for period of two semesters starting from January of the first
semester and ends December of the second semester 2008. Immediately following the
continuation of the FYP I on this project, the student carries on to do study on the
project. In the following dissertation report, it reports on the work that has been
accomplished.
The necessary conditions for attaining optimal bottom hole cleaning below a drill bit is
usually approximated via the optimization of two design criteria: Hydraulic Impact force
and Bit Hydraulic horsepower. The process involves running a circulating pressure test
at the rig site, while keeping the rotary speed and weight-on-bit constant. The test
involves varying the mud pump speed and recording the pump pressure and circulating
rate at each speed.
This paper describes a proven technique that maximizes either the hydraulic impact
force or the hydraulic power of the fluid hitting the bottom of the hole. The objective is
to determine nozzle sizes and flow rate to deliver maximum Hydraulic Horse power
(HHP) or Jet Impact Force (JIF) within specified operating constraints.
In this paper, the introductory part in chapter one talked about the background, problem
statement, Objective and the scope of study. Second chapter covers the literature review
on the study and chapter three the methodology used. Chapter four discusses on the
finding of the study, chapter five discusses the results and final chapter six gives the
conclusion and the recommendation. |
