METHOD OF TESTING PIPE Filed Oct. 24, 1946 INYEN TOR. Hank W Berry.

Patented Sept. 16, 1952 METHOD OF TESTING PIPE Frank W. Berry, Long Beach, Calif assignor, by decree of distribution, to Lois Berry Application October 24, 1946, Serial No. 705,457
Claims.
This invention relates to a method of testin pipe and particularly the tubing through which an oil well or the like is produced.
An object of my invention is to provide a method of testing pipe below the floor of the derrick, i. e., below the surface of the ground and while the pipe or tubing is being run into the well.
An object of my invention is to provide a method of testing pipe in a series of successive steps and while the pipe is being run into the well, stand by stand.
Another object of my invention is to provide a novel method of testing pipe which consists in placing a movable packer in a stand of pipe and preferably at the lower end of this stand of pipe, then filling the pipe above the packer with water and then exerting pressure on the water to determine if the pipe is leaking. As subsequent stands of pipe are added, each stand is in turn lowered into the well and the packer is successively raised into the newly inserted stand of pipe, retaining the column of water above the packer each time that the packer is moved.
Another object of my invention is to provide a novel method of testing pipe which is safe in that there is less danger to the workmen and is quite rapidly performed, and also eliminates the spilling of large quantities of water on the floor of the derrick, as is customary in methods now in use.
Other objects, advantages and features of in- -vention may appear from the accompanying drawing, the subjoined detailed description and the appended claims.
In the drawing: Figure l is a side elevation of a stand of pipe inserted in a well, with parts broken away to serted in a well with parts broken away to showinterior construction.
Figure 4 is a sideelevation of a packer employed in my method.
Referring more particularly to the drawing, the numeral l indicates the drilling table on the floor of the derrick 2. The derrick and the drilling table is shown diagrammatically because the details of this construction are usual and well known and form no part of this invention.
The pipe which is to be tested, for example, the production tubing of an oil well, is run into the well in a series of stands, each stand consisting of a number of lengths of pipe which are threaded together, or to connecting collars. The first stand of pipe shown at 3 is run into the well, and is then held in this position in the table I. A packer 4 is now run into the tubing, and is set at a point adjacent the bottom of the tubing. The packer 4 may be of the type shown in the patent to Brooder No. 350,655, October 12, 1886. However, I do not wish to limit myself to this particular type of packer, since other packers of a movable type may be employed.
The type of packer disclosed in my co-pending application can be released for movement up or down the tubing as desired, and also may be set for any desired point. After the packer 4 has been set in the tubing, a head 5 is attached to the top of the tubing and water is then forced through the head and into the tubing, to entirely fill the same. Pressure is then exerted through the head 5, preferably froma suitable air pump or the like, and the level of the water is noted in the tubing. If the water level drops, it is evident there is a leak in the tubing. The required pressure to test the tubing may vary, but an adequate pressure is exerted to check this tubing at the pressures which will be exerted up on the same when the tubing is in a deep well.
A rod 6 rises from the packer 4 to adjacent the top of the stand of pipe which is being tested, and this rod'can be engaged for the purpose of actuating the packer 4. After the first stand of pipe has been checked. the head 5 is removed and the second stand of pipe 1 is screwed on to the top of the stand 3. The rod 6 is now engaged by a suitable grapple, and the packer ,4 is released after which the second stand of pipe I is run into the well so that the top of the pipe'is just above the surface of the table. Note that while the second stand (and all subsequent stands) are run into the well, the packer 4 is held substantially stationary as far as vertical movement is concerned and consequently the column of water above the packer 4 will be retained with a possible loss of a small. amount of water which might leak past the packer. has been lowered, the acker 4 is again re-set, this re-setting being accomplished through the rod 6, the head 5 is attached to the top of the stand 1, enough water is added to compensate for any leakage, and pressure is again applied to the second stand of pipe, as previously described.
All subsequent stands of pipe as they are run .into the well are tested in the same manner heretofore described.
I have found that it is advantageous to check each stand of pipe as it is run into the well, since it is then possible to isolate any leak, and furthermore, since the testing occurs below the surface After the second stand of pipe I of the ground, there is little danger of injury to the workmen, and also water is not spilled on the floor of the derrick, creating a hazard.
Having described my invention, I claim:
