摘要： A system for evacuating sand, paraffin, and other particulate matter from an oil well, while simultaneously lifting the oil to the surface and stimulating its rate of production, comprises a series of transport units attached to an endless belt. The belt is positively driven between a wellhead station at the surface and a downhole module which is self centering within the well casing, thereby avoiding damage and wear to the casing. Preferably, the belt comprises a roller chain which enables the depth and rate of production of the evacuation system to be easily adjusted. The transport units are replaceably mounted on the belt and are specially designed to agitate and accumulate the particulate member in the oil well.

摘要： A wiper for wiping liquids from the interior walls of various tubular members, such as drill pipe, tubing, casing or internal upset pipe is disclosed which is particularly useful in drilling and workover as the tubular members are withdrawn from a well bore. Features of the wiper include the ability to readily and easily pass through and wipe liquids from restricted passages or bores such as internal upset pipe, means for centralizing the wiper in the passages or bore for efficient wiping, pressure equalization for equalizing pressures within the wiper with outside pressures encountered within the well bore, made from materials which will not create an explosive condition in use, and ease of manufacture, assembly and disassembly, so that the wiper can be manufactured easily, readily and inexpensively, and repairs and replacement of wear prone parts can be readily and inexpensively made. Other features and advantages are disclosed.

摘要： The present invention is directed to an apparatus for installing strain gages or other sensors-transducers in wellbores penetrating subterranean earth formations. The subject apparatus comprises an assembly which is lowered into the wellbore, secured in place, and then actuated to sequentially clean the wellbore or casing surface at a selected location with suitable solvents, etchants and neutralizers, grind the surface to a relatively smooth finish, apply an adhesive to the surface, and attach the strain gages or the like to the adhesive-bearing surface. After installing the condition-sensing gages to the casing or earth formation the assembly is withdrawn from the wellbore leaving the sensing gages securely attached to the casing or the subterranean earth formation.

摘要： Methods for cleaning sand from a helical spring sand filter, methods for assembling a self-cleaning helical spring sand filter, and a self-cleaning helical spring sand filter for use at the petroliferous unconsolidated sand strata of an oil well are disclosed. The filter comprises a helical spring connected in tension at each end to an elongated perforated sleeve for spacing apart all convolutions by a predetermined distance for forming the filter. One or more washer shaped cleaning rings with square holes therein are mounted between adjacent convolutions at one end of the spring for being rotated by a square ended rod supported by a sucker rod in a well between all of the convolutions to the spring other end for scraping off all foreign material from between the convolutions. The spring sand filter can be cleaned for as many times as there are cleaning rings instead of making trips to the surface for unclogging.

摘要： A simple cylindrical paraffin scraping tool adapted to slidably ride up and down between spaced apart stop means on a sucker rod to scrape and remove hardened paraffin and similar deposits from the interior walls of oil well tubing with the scraping tools stored in operative readiness within the well during pumping of the oil well so that the scraping apparatus is immediately available when it becomes necessary to clean the well. Some minor preventive maintenance may be performed during continued pumping of the oil well by incidental agitation of the scrapers preventing and slowing the formation of deposits in the oil well tubing but the principal scraping operation occurs when and as the sucker rod line and attached plurality of scraper tools are pulled out of the well for periodic pump changes.

摘要： A mandrel designed for insertion in an oil pipe string includes a plurality of ring members surrounding the mandrel in a stacked array the upper and lower ends of the mandrel threadedly receiving end members for squeezing the ring members together in a longitudinal direction. A plurality of brush elements extend radially from between adjacent circumferential edges of the ring members, the squeezing force on the ring members holding the brushes in their set position. The sets of brushes from between two adjacent ring members are circumferentially staggered relative to the sets of brushes from the next adjacent ring member so that 360* engagement of the oil well casing takes place when the mandrel is moved through the casing. Either brushes in the form of bunches of stiff wires may be used or rigid block members constituting cutting blades may be substituted for the brushes to thereby enable the casing to be gauged or broached to a given diameter determined by the radial extent of the cutters.

摘要： A gravel packing tool comprised of a tubular member having at least one removable fluid-diverting baffle slidably mounted thereon. The fluid-diverting baffles consist of a pair of rigid half-sleeves that when placed in abutting relationship made to form a cylindrical sleeve. The half-sleeves are hinged at one abutting edge and provided with a latch to lock them in a cylindrical or closed configuration. An outer resilient member consisting of a hub portion adapted to fit around the cylindrical sleeve and an integral, flexible annular flange extending outwardly from the hub portion is bonded to the sleeve. The hub and flange are split adjacent to the latch so that the fluiddiverting baffle can be opened sufficiently to be placed around the tubular member and latched thereon. Retaining means are provided to limit the longitudinal movement of the fluiddiverting baffles on the tubular member.
