Cable mounted bailer for well drilling and cleaning
This invention has special reference to bailers used with cable tool drilling equipment. When drilling a well with this type of equipment, it is necessary to bail mud and debris from the well as the well is drilled progressively deeper. Heretofore many types of bailers have been used to clean out the mud, water, rock, sand, gravel, and dirt as drilling progresses. Some of these devices have a hinged valve at the lower end to permit mud, water, and debris to enter the barrel of the bailer, and various arrangements for dumping the contents of the barrel after the bailer is removed from the well. This bailer includes a barrel, a hinged valve, and a special construction of the bailer which provides for easy and controlled dumping of the contents of the barrel with a minimum of time and effort and insures the positive discharge of the contents into a prescribed dumping area.
