Abstract A body is provided with means for securing it to a tubular member, and the body is provided with a plurality of first helical, flexible cable loops with a portion of each loop facing in one direction and the other loop portion facing in an opposite direction relative to the longitudinal axis of the body to provide leading and trailing portions in each cable loop, and a plurality of second helical, flexible cable loops are mounted on the body with a portion of each loop facing in one direction and the other loop portion facing in an opposite direction, and with the second cable loops being longitudinally offset in relation to the first helical cable loops to form a figure 8 in plan view and thereby provide a plurality of adjacent leading and trailing portions with the leading portions facing in the direction of movement of the tubular member in the well bore to thereby engage the well bore wall and resist collapsing as the tubular member is moved to clean the well bore wall.
A well bore wall cleaner for mounting on a tubular member comprising: a. a body; b. a plurality of first helical cable loops mounted on said body so that a portion of each loop faces in one direction and the other loop portion faces in an opposte direction; c. a plurality of second helical cable loops mounted on said body so that a portion of each loop faces in one direction and the other loop portion faces in an opposite direction, said first and second helical cable loops being offset on said body to overlap each other, whereby the overlapping loops generally form a figure 8 in plan view; and d. means for mounting said body on a tubular member.

A well bore wall cleaner for mounting on a tubular member comprising: a. a body; b. a plurality of first helical cable loops mounted on said body so that a portion of each loop faces in one direction and the other loop portion faces in an opposte direction; c. a plurality of second helical cable loops mounted on said body so that a portion of each loop faces in one direction and the other loop portion faces in an opposite direction, said first and second helical cable loops being offset on said body to overlap each other, whereby the overlapping loops generally form a figure 8 in plan view; and d. means for mounting said body on a tubular member.
Claim 3
Dependent Claim
53 words
The invention of claim 1 including means for securing the end of each loop to said body and wherein said means is disposed at an angle relative to the longitudinal axis of said body to form the helical cable loops and hold the cable against movement to thereby maintain a desired loop size.
Claim 4
Dependent Claim
76 words
The invention of claim 1 wherein said body comprises an elongated strip for securing longitudinally of the tubular member so that the plurality of first and second helical loops form leading and trailing portions with the trailing portion of each loop being opposite the leading portion of another loop so that when the tubular member is rotated to clean the well bore the leading portions resist collapsing and engage the well bore wall for cleaning thereof.
Claim 5
Dependent Claim
24 words
The invention of claim 3 wherein said trailing portions also engage the well bore wall upon rotation of the tubular member for cleaning thereof.
Claim 6
Dependent Claim
89 words
The invention of claim 1 wherein said body comprises an annular member for securing on the tubular member so that the plurality of first and second helical loops form leading and trailing portions with the trailing portion of each loop being opposite the leading portion of aNother loop so that when the tubular member is reciprocated to clean the well bore there are a plurality of leading portions in the direction of movement of the tubular member which resist collapsing and engage the well bore wall for cleaning thereof.
Claim 7
Dependent Claim
24 words
The invention of claim 5 wherein said trailing portions also engage the well bore wall upon reciprocation of the tubular member for cleaning thereof.
