  3.Eccentric Wellhead: Use: In normal circumstances,eccentric wellhead can use for oil extration as the pumping wells with the same wellhead.Replace the annulus testing device and open the 11/4" gate,then can performed the annulus test through logging equipment under test hole.   Working Principle: In normal circumstances,The Eccentric Wellhead can be used as an ordinary wellhead.In the circumstances of the polished rod center deviation, can adjust the position of the tubing,in order to correct the polished rod center deviation. When the annulus test is working,replace the annulus testing device and open the 11/4" gate,then can performed the annulus test through.at work,if need to rotate the eccentric hole,tubing,can rotate the eccentric body to select the appropriate location to use.   Basic Specification: 1.The Eccentric Wellhead applies to the annulus test of 5 1/2"and 7"tubing well. 2.The upper end of the tubing hanger rotation pup joints is 2 7/8"flat tubing buckle,the lower end is 27/8"thicker tubing buckle. 3.Bypass are all 2 3/8"flating tubing buckle or 2"flange plate,connected to pipelines, 4.The upper end of eccentric wellhead is ZG 11/4"buckle,diameter is Φ34mm. 5.Bottom of the housing have Φ211.1rims seal groove compatible with the wellhead for-way. 6.Tubing located bearing box load is more than 70 tons,and enough to ensure the load rotarion. 7.Sealing pressure is 14MPa.
