42、. Summary of Practice4.1 Wireline drilling is a rotary drilling process that usesspecial enlarged inside diameter drilling rods with speciallatching pilot bits or core barrels which are raised or loweredinside the rods with a wireline and overshot latching mecha-nism. The bottom section of rod has e

43、ither a diamond orcarbide coring bit at the end and is specially machined toaccommodate latching of either pilot bits or core barrels. Theovershot mechanism is designed to latch and unlatch bit orbarrel assemblies. Bit cutting is accomplished by application ofthe combination rotary and static down f

44、orces to the bit.General drill-hole advancement may be performed withoutsampling by using either a pilot roller cone or drag bit until thedesired depth is reached. Alternately, the material may becontinuously or incrementally sampled by replacing the pilotbit with a core-barrel assembly designed for

45、 coring either rockor soil.4.2 The pilot bit or core barrel can be inserted or removed atany time during the drilling process and the large insidediameter rods can act as a temporary casing for testing orinstallation of monitoring devices.5. Significance and Use5.1 Wireline casing advancement may be

46、 used in support ofgeoenvironmental exploration and for installation of subsur-face monitoring devices in both unconsolidated and consoli-dated materials. Use of direct-rotary wireline casing-advancement drilling methods with fluids are applicable to awide variety of consolidated or unconsolidated m

47、aterials aslong as fluid circulation can be maintained. Wireline casing-advancement drilling offers the advantages of high drilling-penetration rates in a wide variety of materials with the addedbenefit of the large-diameter drilling rod serving as protectivecasing. Wireline coring does not require

48、tripping in and out ofthe hole each time a core is obtained. The drill rods need onlybe removed when the coring bit is worn or damaged or if theinner core barrel becomes stuck in the outer barrel.5.1.1 Wireline casing advancers may be adapted for usewith circulating air under pressure for sampling w

49、ater-sensitivematerials where fluid exposure may alter the core or incavernous materials or lost circulation occurs (1, 2).3Severaladvantages of using the air-rotary drilling method over othermethods may include the ability to drill rather rapidly throughconsolidated materials and, in many instances, not require theintroduction of drilling fluids to the borehole. Air-rotarydrilling techniques are usually employed to advance theborehole when water-sensitive materials (that is, friable sand-stones or collapsible soils) may preclude use of water-b
