The Study And Application Of Blanketing New Material Resisting-scrape Inside The Oil-tube And The Blanketing Technology

With the 40 years development, the shengli-oil-field has gone into the intermediary and later stage, and the containing water rate of the oil well is increasing, the difficulty to raise the liquid has enhanced, the etch has become seriously when the rod pump whips the polished staff. That cuts down the production period of the oil well, increases the operation expense and the operation time, makes the oil tube and whipping staff become waste sooner. Therefore it increases the exploitation cost. In order to resolve the partial scraping problem of the rod and casing in the well, this text analyses the component and the character of the composite resin paint with carbon and zirconium. By means of the test, we studied the performance of the oil tube blanket with the composite resin paint, which includes the high temperature-high pressure-resisting etch, adhere intensity , resisting and reducing scrape. Based on the character, we plan and design the manufacture system of oil-tube paint. It supplied the guaranty for the industrialization of the component and the character of the composite resin paint with carbon and zirconium. After the industrialization, this technique is applied on the spot, which can induce the partial scraping of the rod and casing, prolong the exempt-from period, decrease the rod and casing expense, resolve the problem of tube-etch and scour. That can supply the producing technique which has better resisting etch and resisting scrape for the oil-field exploitation, and since the auxiliary is simple, and the operation is convenient, the technique has significant economic and social benefits in the decreasing-cost and increasing-benefit aspect of the oil-field.
