In the repair, maintenance and stimulation of oil and gas wells, numerous equipment like inflatable packers and inflatable plugs are used, which can be produced either in permanent packers or permanent Recycled. It is not likely to eliminate and repair permanent apparatus deep in the drilled well, but recyclable plugs can be simply detached from the well by putting on a definite force. Such tools make it conceivable to do processes like selective acidification; wellbore sealing, selective cementing and well repair deprived of take the production line away. Plugs are prepared in diverse lengths, diameters and forms. The enduringly swollen plug permits the operator to block the well deprived of leaving the production line or removing higher production areas. The plug plugs are passed from side to side of the brain tube and after reaching to the wanted depth, swell and achieve the process of wall tube hindering the oil and gas wells. The application of permanent swollen plugs is in the lower zone of the well (lower zone shutoff) or permanent well abandonments. Utmost of the cost-effective plugs are everlastingly prepared and their benefit is the design simplicity and installation at ease rather than that of recyclable plugs.
The product is a permanent inflatable plug in the well, which has a substantial role in decreasing the period and price of many processes in the well.
Features and profits of this product are according to following:
- Capability to do operations deprived of removing the manufacturing line
- Ability to drive tools into the well with the aid of movable brain tube as well as cable well-appointed with emergency separation appliance (Emergency Disconnect). These devices are linked to a movable brain tube or cable with the aid of a tool called Running Tools.
- Usable in vertical, horizontal and tilted wells
- Stand relatively high pressure change in the 7-inch wall pipe at a temperature of 280 o F accepted by the National Company for Southern Oilfields according to API 11D1 (ISO 14310)
- Low elongation (700%)
The swollen sealing element is recognized as the central technology of this product. Elastomeric parts are extensively used in sealing in-well tools and temporary and permanent sealing of wall pipes and open cavities. Elastomers experience very corrosive and severe circumstances due to high temperature and the presence of H2S, CO2, chlorine, etc. in oil and gas wells. Moreover, this equipment is exposed to tough tensile and compressive forces. So, elastomers used in this business have to possess a very high expertise and methodological knowledge. The features and benefits of inflatable sealing elements are: high level routine even in triple swelling compared to the original size, tolerance of high pressure change temperature make them very appropriate for all kinds of wall pipes. For attaining stated possessions, it is created from nanoparticle reinforced elastomer to offer the facility to increase the elongation of more than 700% while keeping the essential strength.
