Abstract Of The Disclosure A wash tool includes a housing having upper and lower packer cups attached thereto for sealing between the housing and a casing bore and defining an upper well annulus por- tion, an intermediate well annulus portion, and a lower well annulus portion. The housing has an upper fluid bypass passage defined therethrough communicating the upper portion and intermediate portion of the well annulus. The housing includes a lower fluid bypass passage defined therethrough for communicating the intermediate portion and the lower portion of the well annulus. A longitudinal housing bore is defined through the housing and has an open lower end so that fluid in the lower portion of the well annulus may return up through the housing bore. The lower packer cup wipes the casing bore as it advances downward through the casing. The fluid exiting the upper bypass passage exits through downwardly directed jets so as to jet wash the intermediate portion of the well annulus as the tool advan- ces down through the casing bore.
