n: the hole made by the drilling bit, which can be open, cased, or both. Also called borehole, hole, or wellbore.

n: The filtrate and clay of drilling fluid intruding into the formation in drilling and completion,then degrade the permeability and production capacity.

n: The ratio of the quantity of qualified completed well to the total completed well.

removal of solids, completion fluid, sand workover fluids by production.

n: The ratio of production of hydrodynamical completely penetrating well to hydrodynamical imperfect well.

n: 1. the activities and methods of preparing a well for the production of oil and gas or for other purposes, such as injection;the method by which one or more flow paths for hydrocarbons are established between the reservoir and the surface. 2. the system of tubulars, packers, and other tools installed beneath the well- head in the production casing;that is, the tool assembly that provides the hydrocarbon flow path or paths.

n: The last working process before the well start to produce,which include open hole completion, sand control completion and tubingless completion,etc.








that processes involved, after drilling, is properly isolate pressures and fluids, and then stimulate or restrain the formations so that hydrocarbons can be produced with minimum amounts of extraneous fluids.

n: The wiper trip and reaming to wellbore by tripping in drill string.

the drilling and completion steps prior to production.
