Description

METHOD FOR FACILITATING THE OPERATION OF A VIBRATORY SCREEN Field of the Invention This invention relates to a method for facilitating the operation of a vibrating screen. The invention also relates to a screen and vibrating screen assembly. BACKGROUND OF THE INVENTION In drilling a borehole in the construction of an oil or gas well, a trepan is placed at the end of a series of drill rods and rotated to drill the borehole. A drilling fluid known as "drilling mud" is pumped through the series of drill rods to the trephine to lubricate the trephine. The drilling mud is also used to carry the materials produced by the trepan cuts and other solids to the surface through a void formed between the series of drill rods and the borehole. In drilling mud it contains expensive synthetic oil-based lubricants and it is therefore normal that the drilling mud used is recovered and reused, but this requires that the solids be removed from the drilling mud. This is achieved by the processing of the drilling fluid. The first part of the process is to separate the solids from the solids carried by the drilling mud. This is achieved at least partially with a separator Ref. 191677 vibratory, such as the vibrating screens described in US 5,265,730, WO 96/33792 and WO 98/16328. Vibrating screens generally comprise an open bottom basket having an open discharge end and a solid wall feed end. A number of rectangular sieves are placed in the basket, which are retained on C-shaped channel rails located on the basket walls, such as those described in GB-A-2, 176-424. The basket is placed on springs above a receiver to receive the recovered drilling mud. A drawer or pit is provided below the open discharge end of the basket. An engine is fixed to the basket, which has a drag rotor provided with the weight of a counterweight block. In use, the motor rotates the rotor and the weight of the counterweight block, which causes the basket and the sieves fixed thereto to shake. The mud that carries the solids is introduced in the feeding end of the basket on the sieves. The stirring movement induces the solids to move along the sieves towards the open discharge end. The drilling mud passes through the sieves. The recovered drilling mud is received in the receiver for further processing and the solids pass over the discharge end of the basket to the drawer or pit.
There are already a variety of systems and methods for using surface acoustic wave labels or radio frequency identification labels on identification items, including items used in the oil and gas industry such as a drill pipe. (See, for example, US Patent Nos. 4,698,631, 5,142,128, 5,202,680, 5,360,967, 6,333,699, 6,333,700, 6,347,292, 6,480,811, and US Patent Applications Serial Nos. 10 / 323,536 filed on December 18, 2002, 09 / 843,998 filed on April 27, 2001, 10 / 047,436 filed on January 14, 2002, 10 / 261,551 filed on September 30, 2002, 10 / 032,114 filed on December 21, 2001, and 10 / 013,255 filed on December 5, 2001. November 2001, all fully incorporated here for all purposes). In many of these systems, a radio frequency identification tag or "RFIDT" is used in the pipeline at a location that is either inside or outside a pipe, because RFIDT is exposed to temperatures and extreme conditions down the well in a borehole. Frequently, a RFIDT thus placed fails in its operation and is no longer used. Also, in many cases, RFIDT thus placed is subject to damage above ground due to the rigors of handling and handling.
The principle of operation of a SAW RFID tag is based on the conversion of an interrogation radio wave impulse emitted from a reader directly onto a nano-scale surface acoustic wave on the surface of the SAW tag. The label antenna is connected directly to an IDT (Interdigital Transducer) that uses the piezoelectric effect in a lithium niobate substrate material to perform an efficient conversion between radio waves and surface acoustic waves. These surface acoustic waves then travel once an encoded set of reflectors has been passed from the waves that interact to produce a single pulse train of acoustic waves. These impulses are converted directly into a reply signal of the coded radio wave that is sent back to the reader. The SAW (chip / integrated circuit) tag operates using the piezoelectric effect and does not require DC power. In the drilling of an oil or gas well, the drilling fluid carrying the solids, returned to the surface, is analyzed frequently and the results of the analysis are used to determine a suitable medium for the separation of the solids from the drilling. The analysis is also used to determine if the necessary additives have to be added to the fluid drilling. The means determined to separate the solids from the drilling fluid carrying the solids, often involve specifying a particular mesh size of the screen, the type of mesh and the type of mesh assembly. It is often difficult to recognize a particular type of screen by visual inspection. Errors can occur in the choice of the type of screen. In addition, the determined means may require specific speeds of operation of a screen, the operation at a particular inclination to contain a puddle of the drilling fluid that transports the solids to a certain depth to increase or decrease the hydrostatic head of the drilling fluid on the sieve and to increase or reduce the residence time of the drilling fluid that transports the solids onto the screen, both of which can be achieved by altering the angle of inclination of the screen from the inlet end to the discharge end of the screen . In angle of inclination of the sieve can be adjusted from downhill (perhaps between 3 and 30 degrees, more preferably 3 and 10 degrees), in a flat place and uphill, (with an uphill angle from the horizontal of between 3 degrees and 10 degrees, more preferably between 5 and 9 degrees). Certain screens will be able to do this and others will not. The sieves are of different size and type mesh. The mesh can be unidirectional, requiring a certain orientation in the vibrating screen. It is extremely important to use the correct screen. BRIEF DESCRIPTION OF THE INVENTION In accordance with the present invention, there is provided a method for facilitating the operation of the vibrating screen, the method comprising the steps of having an identifier that can be read by a computer on the apparatus associated with the separation equipment. , the identifier that can be read by a computer stores information and reads the information stored in the identifier that can be read by the computer with a reading device. Preferably, the information is stored in the identifier that can be read by the computer. Advantageously, the information stored in the identifier that can be read is sufficient to determine the parameters of the separation equipment. In the case of a screen assembly, the information will be in at least one and preferably all of the following elements: the type of mesh, the size of the mesh, the number of layers of the mesh; if it is prestressed or is made of hook-shaped strips; the size of the frame (length, width and depth) that is to say all the physical parameters, as well as the manufacturer, the date of manufacture and other information to make it possible for the separation equipment to be tracked to its manufacture In the case of a vibrating screen: one, two or three auxiliary deck machines; if it exists, a covering of the uncured sieve; the type of the sieve fixing means; the manufacturer, the size of the printing area; the height; the width; the number of primary screens that can be fixed on the primary covers; Adjustable tilt covers and adjustment range. Advantageously, the information stored in the identifier that can be read is an identification code, the method also includes the step of entering the identification code in a field in a database, sufficient information to determine the parameters of the equipment of separation stored in the database that refer to the identification code.

Preferably, the acceptance or rejection analysis signal is displayed to a user, such as a drill assistant or other operating member. Preferably, the method further comprises the step of inserting in the parameters of the computer program of the separation equipment that are suitable. Advantageously, the method further comprises the steps of analyzing the separation process, formulating the parameters of the separation equipment that could be suitable, inserting these suitable parameters into a computer. For example, if the driller notifies from his instruments, or from an inspection Visual that the drilling fluid is overflying on the sieves in the agitator, it determines the cause of the problem, such as the agglutination of nearby particles of the sieve. Therefore, the driller introduces the appropriate parameters for an alternative screen to be used, which will reduce the likelihood that nearby particles will agglutinate. An operating member is alerted to change the sieve. The operating element uses a portable reading device to read the identifiers on a selection of the screens. The reading apparatus will otherwise display or alert the operating member when it passes the reading apparatus over a screen that matches the proper parameters of the perforator inserted in the computer program. The computer program may comprise a database and preferably comprises a look-up table.

The layer (s) of the screening material 946 may be any undulating or projection screening material, including, but not limited to, those described in US Pat. 6,450,345; 5,868,929; 5,720,881; 5,958,236; 5,876,552; 5,636,749; 5,417,858; 5,417,793; 5,417,859; and 5,944,993, all fully incorporated here for all purposes. In the screening assembly 940, a portion of the layers 946 may pass the layer (s) 942 between the bottom and bottom edges of the side mounts 944 and, if desired, towards the top edge. Alternatively, only the layer (s) 942 is (are) secured within the side mounts 944. The side mounts 944 may have a energisable identification apparatus 944a similar to the energisable identification apparatuses shown and / or described for the embodiment of Figure 8D. Figure 9A shows a screen 1110 according to the present invention with a base, support or lower frame 1112, three undulating mesh screens 1114 (any two of which may be removed) on and / or attached or connected to frame 1112, and, optionally, an upper mesh or screen 1116. Screens 1114 may be, by themselves, stitched, joined, or glued together, for example, with epoxy, glue, welding and / or sintering. The rubber strips, plastic tape strips, cushion or cushions 1118 are placed between the screen 1114 and the upper stream 1116. The strip (s) or cushion (s) 1118 are optional. As shown, the strip (s), belt (s), or cushion (s) 1118 are secured to the sieve 1114 (or ridges thereof), but it is within the scope of this invention to secure them (or some of them). they), to sieve 1116. To effect such assurance, any suitable sizing, epoxy, welding, and / or sintering can be used. The frame 1112 can be any known, suitable base, frame or support. It is within the scope of this invention for the screen 1114 to be any screen, mesh, screens, meshes, known, or combinations thereof, attached, together, not attached, or attached only in certain locations and in any manner known as observe from above or on one end (as in Figure 9A). It is within the scope of this invention for the upper sieve 1116, which is optional, to be any known sieve, mesh, sieves, meshes, or a combination thereof, joined together or unattached, and with any shape known As shown in Figure 9B, the sieve 1114 is three single-mesh screens attached together with a coarser mesh on the bottom, the intermediate mesh on the middle part, and a finer mesh on the top. Screen 1116 as shown, may be a coarser screening screen of a coarser mesh than the finer mesh of screen 1114 or a coarser multi-layered mesh. In another aspect, the screen 1114 is a single screen of a finely woven mesh made of any suitable material, for example of stainless steel and / or of a plastic material and the 1116 screen is a single screen of a coarser mesh made of any suitable material (for example but not limited to stainless steel and / or plastic), with the 1114 screen on a metal or plastic frame or support. Alternatively or additionally, instead of the frame 1112 of any perforated plate, strip, support, or series of strips or supports, known, may be used. In one aspect, the strips 1118 are fused plastic strips aligned with the peaks of the undulating fine mesh. Such strips may be made of rubber (for example of nitrile) or of plastic, for example of polypropylene, to inhibit or prevent abrasion of the finer meshes. Such strips can be glued to the bottom of the screen 1116 and / or to the screen 1114. Also the screen 1116 can be glued to the screen 1114.
The end plugs 1113 and 1115 (Figure 9D) closely seal the open ends of the screen 1110. These end plugs can be made of rubber, metal wood, plastic, a Teflon or urethane material. The plugs 1113 extend along two sides of the screen along the ridges of the screening material to completely seal the sides. The plugs are held in place by a friction, glue, epoxy, sintering and / or welding adjustment. Alternatively, the ends can be covered with a screening material. The flow of fluid on the screen 1110 from either end can be from the top to the bottom as seen in Figure 9A, from the bottom to the top, or from one side to the other. In one aspect, the sieve 1116 is a debonding screen of a woven steel mesh. In another aspect, it is made of a plastic or synthetic mesh or woven composite material; and in another aspect, it is a combination of a steel and plastic mesh or a synthetic material or a composite, woven material. The screen 1116 may be of the same mesh or of a coarser mesh than that of the screen 1114 of any layer thereof. In one embodiment, the areas 1117 between the sieve 1116 and the sieve 1114 are open. The sieve 1116 protects the screen mesh 1114 from the abrasive particles. When the sieve 1116 is of a coarser mesh than that of sieve 1114, the relatively larger particles retained on sieve 1116 are prevented from damaging and / or preventing flow through sieve 1114. With sieve 1110 as shown and with the sieve 1116 optionally, the flow of the liquid through the screen is increased by reducing the thickness of the bed of the solids of the finer mesh sieves by separating larger particles with the sieve 1116. Figure 9E shows an alternative embodiment of the sieve 1110 with identical parts (indicated by the same numbers) but with additional end plugs 1119 between upper sieve 1116 and sieve 1114. Such "double sealing" can be used either on one or both ends of the sieve. A fluid and / or the particles introduced to the sieve 1110 first meet the sieve 1116 and then the material with the material flowing through the sieve 1116, flows to the sieve 1114. The plugs 1119 can be made from the materials described for the plugs 1113, 1115 and the plugs 1119 can be installed and / or similarly secured in place. Any of the plugs 1113, 1115, 1119 can be removed in certain embodiments. As previously described, any energisable identification apparatus previously described may be applied to any part of the sieve 1110. An energizable identification apparatus 1120 is interleaved within a plug 1115 and / or a energizable identification apparatus 1122 is interleaved within a plug 1113. Optionally, an energizable identification apparatus 1124 is interleaved within the a sieve 1119 (Figure 9E). Optionally, an energizable identification apparatus 1126 with an antenna 1127 extending therefrom, is located within the frame 1112.
