插图:The unique issues associated with ERD wells largely stem from the high inclination of thewell that is required to reach the objective departures. Tangent" sail" angles in some ERD wellshave been 80度or higher. "Average" angles from surface to TD have been 70度or higher. Some ERDwells have in fact been drilled as extremely long horizontal wells where the bulk of the well hasbeen drilled horizontally (defmed as an inclination of 88度or more).At such high inclinations, the transport of cuttings from the well is more difficult than invertical wells. As a result, higher flow rates, tighter control of drilling-fluid rbeology, and the useof non-conventional mechanical means to assist hole cleaning must he used. Such mechanicalmeans might include high drillstring rotation (off-bottom) or the use of special, bladed drillpipeto stir cuttings beds mechanically. High rotary speeds and backreaming help clean the hole butcan increase drilling shock&and cause fatigue or backoff of motor housings. Therefore, suchpractices should be viewed as secondary hole-cleaning methods and used only if primary holecleaning is inadequate. A common method of removing cuttings beds is the use of low-viscositysweeps that scour the cuttings off the low side of the hole; high-viscosity sweeps are then madethat carry the dislodged cuttings to the surface. The fundamental driver of hole cleaning,however, is flow rate, and high flow rates are strongly recommended throughout high-inclinationsections if ERD allows. For this reason, the rig' s pump and piping capacities with regard to flowrate, pressure, and the drillstring design are critical.Other implications of high inclination include the greater likelihood of mechanical wellboreinstability and hence the need for careful mud-weight planning. Since more formation is exposedfor longer periods, chemical stability also becomes more critical.Aside from hydraulics and formation
