Daqing Oilfield: New Technology Relieves Piston Pump Water Injection Pressure

In order to solve the problem of low permeation rate and high water injection pressure in peripheral oilfields, mining of No. 74 mine in Daqing Oilfield has strengthened the study of periodic injection technology, effectively improving the water displacement effect and easing the rate of water injection pressure increase. Daqing Mining No. 4 and 4 mine belongs to the Daqing peripheral oil field Taizhao block permeability is low, crude oil viscosity, wax content, crude oil freezing point higher. Water injection pressure rises rapidly due to the development of reservoir fractures. In the early 2000, the average water injection pressure was 12.2MPa, and the injection pressure rose to 19.02Mpa in 2002. This mine water injection system plunger pump up to 25.0MPa pressure, water injection pressure by 2010 will reach the maximum limit of existing water injection equipment. To this end, the mine organization special research group aimed at the heterogeneity of the reservoir in Taizhao Oilfield, from 2002 to gradually implement the cycle of water injection technology. In the whole ore 115 water injection wells, 111 wells were injected with periodic water injection. In the past 4 years, the average water injection pressure increased by only 0.78Mpa. The water injection pressure in Taizhao area has been eased up.

Nylon Sanding Belt

This product is suitable for portable and desktop automatic grinding instruments, with elasticity and small grinding force, which can improve the grinding grain of workpiece well, and is easy to replace. Compared with traditional abrasive tools, nylon abrasive belt has the following advantages: it can control the minimum grinding amount, grinding depth, anti-blocking, and the probability of exceeding tolerance is the smallest. The product continuously exposes new abrasive layer during the grinding process, and the grinding effect is good.

1. Great multi-purpose belt, ideal for cleaning, finishing, blending and deburring
2. Nylon film backing is stretch resistant for close, ongoing cutting action
3. The film backed belts work great on stroke sanders when reduced friction on the back of the belt is desired
4. Gaps between nylon fibers allow debris to escape, helping to reduce loading
5. Fibers break down gradually to reveal fresh mineral, producing consistent cuts
6. Available in a range of grades, minerals and converted forms,Coarse( Brown 150# ), Medium ( Red 240# ), Fine ( Blue 400# ) , Very Fine ( Grey 600 # )
Our Surface Conditioning Belt is a durable belt engineered to perform detail work such as blending, blending corners, cleaning, contour finishing, deburring, deburring edges, fine finishing, flat finishing, setting the grain, stainless steel finishing, and attaining straightline-brushed finishes on a variety of metals.

We distributes and wholesales various brands of Abrasive Sanding Disc, Cutting Wheels , Abrasive Flap Disc, Flap Wheels , Flap Disc Backing Pad, Flap Disc Adhesive , Abrasive Machine and Surface Conditioning Product etc, and enjoy a high position among consumers.

Ideal for Robotic Finishing
With a wide range of conformability options and high consistency, long-lasting industrial abrasives are a great option for robotic metal finishing. Surface Conditioning Belts can generate a spec-required, aesthetic finish when used in both manual and robotic processing.

Multi-Purpose Belt Great for Tackling Multiple Applications
Working on flat parts especially - requires a belt that will abrade the surface closely. Our Surface Conditioning Film Backed Belt was designed to do just that. The nylon-backed belt has a reduced friction backing and is low stretch, so it's unlikely to yield or stretch when run. This belt backing works well when the standard scrim belts stretch and fall off the machine.

Versatile Belt Options

One of the best benefits of our Surface Conditioning Film Backed Belt is its versatility. Offered in a range of minerals, grades and converted forms, you're likely to find the right match for your application. Choose between silicon carbide or aluminum oxide mineral. Aluminum Oxide is available in coarse (CRS), very fine (VFN), and medium (MED) grades. Silicon carbide is available in super fine (SFN), very fine (VFN), and medium (MED) grades. Aluminum oxide is a synthetic mineral known for its sharp cut, durability and long life. Silicon carbide tends to break down faster than aluminum oxide but will also produce a finer finish.

The Many Benefits of Our Belts Available in narrow, wide and standard sizes, this belt is commonly run on a belt sander. Given their narrow widths, narrow belts tend to be a good match for workpieces with narrow areas and nooks and crannies, like lobes on a crankshaft or camshaft. Conversely, wide belts are a good match for larger workpieces like stamped parts, sheet metal parts, or dies. Independent of belt chosen, operators can rely on consistent performance; it's what they've come to expect from our abrasives. Non woven technology makes our industrial abrasives - and belts - unique. A combination of fiber strands, resin, and abrasive mineral forms a thick, open web.

Surface Conditioning Belt work well to remove coarse grind lines, mill marks, or small burrs left by cutting tools or conventional abrasives. Abrasive belts come in many different widths and lengths and are used on a variety of different belt sanding tools for many different applications on both wood and metal.
