Significance and Use4.1 Cable-tool rigs (also referred to as churn rigs, water-well drilling rigs, spudders, or percussion rigs) are used in the oil fieldsand in the water-well industry.

36、 The Chinese developed the percussion method some 40004,000 years ago.FIG. 1 Drilling ToolsD5875/D5875M 1834.2 Cable-tool drilling and sampling methods may be used in support of geoenvironmental exploration and for installation ofsubsurface water-quality water quality monitoring devices in both unco

37、nsolidated and consolidated materials. Cable-tool drillingand sampling may be selected over other methods based on its advantages, some of which are its high mobility, low water use,low operating cost, and low maintenance. Cable-tool drilling is the most widely available casing-advancement method th

38、at isrestricted to the drilling of unconsolidated materialssediment and softer rocks.4.2.1 The application of cable-tool drilling and sampling to geoenvironmental exploration may involve sampling unconsolidatedmaterials. Depth of drill holes may exceed 900 m 3000 ft and may be limited by the length

39、of cable attached to the bull reel.However, most drill holes for geoenvironmental exploration rarely are requiredneeded to go that deep. Rates for cable-tool drillingand sampling can vary from a general average of as much as 7.5 to 9 m/h 25 to 30 ft/h including setting 200 mm 8 in. diametercasing to

40、 considerably less than that depending on the type(s) of material drilled, and the type and condition of the equipment andrig used.NOTE 2As a general rule, cable-tool rigs are used to sample the surficial materials, sediments (that is, overburden), and to set surface casing in orderthat rotary-core

41、rigs subsequently may be set up on the drill hole to core drill hard rock if coring is required. needed.NOTE 3The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of theequipment and facilities used.

Users of this standard are cautioned that compliance with Practice D3740 doesnot in itself assure reliable results. Reliable results d

The monitoring device(s) may be in

If necessary, the casing may also be left in the borehole as part of the device.NOTE 4The user may install a m

Apparatus5.1 Cable-tool rigs (see Fig. 2) have a string of drill tools with a drive clamp (see Fig. 1 and Ref (2) on the drill string connectedby wire rope that periodically

46、 can be hoisted and allowed to “fall” for percussion drilling in unconsolidated and consolidatedmaterialssediment and for driving/retrieving casing. The full string of drilling equipment consists of drill bit (see Fig. 1 and Ref(3)Regular bit used for all-around general drilling and, Ref (4)Star bit

47、 used for chopping and breaking hard materials androck), drilling jars (optional), and a drill stem (see Fig. 1 and Ref (5), with a swivel socket (see Fig. 2) connected by a wire ropefastened to a drum called a bull reel that raises and lowers the drilling tools and permits percussion drilling eithe

The spudding beam, commonly referred to as the walking beam, that is driven by the pitman andcrank, imparts a reciprocating motion to the drilling line.NOTE 5All cable-tool Cable-tool rigs have the capacity to lift and drop heavy drive clamps for insta

If the bit becomes stuck in the borehole it can normally be freed by upward blows of the drilling jars (jars can also beused in the same mode to extract casing). The primary function of the drilling jars is to transm
