Downhole tool packer, investigation of things Petroleum Technology (certification), downhole tools

DB-90 at the bottom of a tee, uses DB- bottom tee mounted on the lower portion of the column pump, oil and water wells division process string matching tools, as pump has been started on the movement of oil, started to close down. Second, under the structure of joints, couplings, tee, the middle joint, the joint. Third, the principle that DB- bottom of the tee installed between the pump deep well pump coupling bottom packers downhole tool compensation, the pump and lower motor driven ball on the bottom of the tee at Kai Kai to the ball and tee to seal, seal reliable, easy to use, to increase production. Safety joint is the joint connection in the drilling, workover, testing, cleaning, fracturing, acidizing and other operations in the column for special purposes, when working properly downhole tool string packer can withstand tensile, compressive and shock loading and to ensure the smooth flow of the column. When the string sticking, first disengage from security joints, pulled out of the column above the joint, re-processing the lower part of the column, the next step to simplify operating procedures. Second, the structural principle of the tools are the joint Aprons, under the joint insurance nails and other components. K344-113 packer for the expansion of fishing tools downhole tool, outward expansion by plastic tube to seal grease casing annulus. Therefore, the internal pressure of downhole tools, plastic tube must be greater than the external pressure, which is the rail pressure must be greater than the casing pressure. So, K344-113 expansion packer must be supporting the use of restrictor. Its expansion injection holes strainer can prevent sand entering the plastic tube, plastic tube to ensure that no sand cards. First, use for water, acidification, fracturing, looking string, such as string closure. 1, the working principle packer: Add hydraulic hose from the hydraulic through filters, eyelets and the center of the pipe under the sink joint role in the lumen of the plastic tube, so that the plastic tube to swell, sealing grease casing annulus . Deblocking: let go of the pressure tubing, and cones to recover re-opened. Downhole tool packer, investigation of things Petroleum Technology (certification), downhole tools provided by the nature of things, Dongying Petroleum Technology Development Co., Ltd. Ge Wu Dongying Petroleum Technology Development Co., Ltd. (www.dygwsy.com) is Dongying, other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the nature of things Petroleum Technology leadership with the staff warmly welcome all inquiries negotiations to create the phenomena of nature Petroleum Technology better future.
