Low profile dual screen prepack

A prepack sand screen assembly has resistance welded inner and outer screens concentrically mounted in radially spaced relation onto a perforated mandrel, thereby defining an annulus in which prepack gravel is loaded. The longitudinal spacing distance between adjacent turns of the inner and outer screens selectively exclude sand fines of a predetermined minimum size. The outer screen wire is substantially greater in size as compared to the corresponding dimension of the inner retention screen wire. The inner retention screen is radially spaced with respect to the perforated mandrel, thereby defining a bypass flow annulus. The effective inlet flow area through the inner retention screen is more than twice the effective inlet flow area through the outer screen. Accordingly, localized deposits of sand fines on the inner screen are effectively bypassed by the remaining flow passages formed across the inner retention screen. According to this arrangement, the dual screen prepack assembly excludes sand fines from inflowing formation fluid during the initial production phase following a gravel pack operation, without limiting production of formation fluid.

Method of and apparatus for filtering

Method of and apparatus for filtering

The invention provides a method of and apparatus for filtering which provides the filtering of extremely small particles, greater dirt retention in the filter medium, higher flow rates through the filter medium, a smaller volume of filter medium, and improved backflushing or backwashing to obtain a cleaner medium. The medium is composed of finely divided particulate material which in the preferred embodiment is polyvinyl chloride, polyethylene or wood sawdust, these materials being light and having great strength to provide stable, fine particles capable of being backflushed. While the apparatus can assume many different configurations, liquid permeable retainers preferably are provided at both the inlet and outlet sides of the filter medium. Where the filter medium is located between retainers, it is important to reverse the liquid flow at least through the inlet retainer during backflushing to remove any deposits from that retainer. As will be described, it is possible to use only one liquid permeable retainer together with agitation and hydraulic flow during backflushing to provide a simplified filter which is effective in some applications. The invention also features backflushing of a particulate filter medium which is very compact and contains relatively great dirt loads. Such backflushing utilizes both mechanical and hydraulic forces, and may be accomplished in several different ways. The media can be compacted, if desired, to reduce the size of the voids therein, thereby increasing the effectiveness of the filter medium in entrapping and holding extremely small particles of dirt therein. The filter medium is compacted prior to the filtration operation, such compaction being accomplished in any one of several ways, e.g. by the use of fluid pressure or a differential flow rate.

Method of filtering

This invention provides a method of and apparatus for the deep bed filtration of a liquid containing fine particles (generally on the order of less than 0.005 inches) to obtain an effluent of exceptional clarity. It has been discovered that filtration to this degree of clarity requires a compacted filter medium bed and that this bed compactness must be preserved during rejuevenation of the bed to avoid the dispersal of previously removed dirt particles throughout the filter medium. In this invention, the rejuevenation of the bed is carried out by the flow of liquid through the bed in the same direction as the direction of filtration, but at a flow rate at least twice the flow rate during filtration, while maintaining the configuration and compactness of the bed during both filtration and rejuevenation.
