Wireline retrievable jet cleaning tool

A wireline retrievable jet cleaning tool for simultaneously cleaning a plurality of longitudinally spaced, predetermined target area inside well tools and tubulars, the jet cleaning tool comprising a longitudinally extending axle, a nozzle housing rotatably mounted around the axle, and means for providing fluid communication through the axle and nozzle housing, the nozzle housing further comprising a plurality of longitudinally spaced nozzle sections, each nozzle section comprising at least one circumferentially rotatable fluid spray nozzle for sweeping at least one jet of a pressurized cleaning fluid circumferentially over each of the target areas.

The jet cleaning tool of claim 15 wherein the means for sweeping jets of the pressurized cleaning fluid over the target areas further comprises a fixed longitudinal shaft member extending below and slidably engaging the nozzle housing, upper and lower cylindrical guide members slidably engaging the shaft member below the nozzle housing, spring means disposed between the guide members to bias the guide members longitudinally apart, the nozzle housing being adapted upon provision of the cleaning fluid at a sufficient pressure to overpressure the spring means and force the upper spring guide toward the lower spring guide against the bias.

A jet cleaning tool adapted for deployment by wireline equipment inside a well tool or tubular, the tool comprising:

• a nozzle housing having a plurality of longitudinally spaced nozzle sections, each section comprising means for receiving a pressurized cleaning fluid, forming jets of the fluid and sweeping the jets both longitudinally and circumferentially over longitudinally spaced-apart target areas inside the well tool or tubular;
• and
• means for longitudinally reciprocating the nozzle housing responsive to pressure variations in the pressurized fluid.

A longitudinally reciprocating jet cleaning tool adapted to deployment by wireline equipment inside a well tool or tubular, the tool comprising:

• a rotatable nozzle housing, a concentrically disposed axle and a biasing means exerting pressure on the nozzle housing, a plurality of longitudinally spaced nozzle sections within the nozzle housing, each nozzle section being adapted to sweep jets of a pressurized cleaning fluid both longitudinally and circumferentially over longitudinally spaced-apart target areas inside the well tool or tubular the nozzle housing being adapted to slide longitudinally along the concentrically disposed axle whenever sufficient fluid pressure is supplied to the tool to overpressure the biasing means.
