Table 3 Performance indicators
Specifications, mm
Ensure that the lower sleeve does not float
4.3.1. The plug shall be made of 35CrMo steel specified in GB 3077 or materials with equivalent mechanical properties. 473.10
4.3.2 The socket shell can be made of thick-walled sleeves of J-55 or lower steel grade, or 35 steel specified in GB699 or materials with equivalent mechanical properties.
4.3.3 The internal components of the socket are made of materials with good drillability. The sleeve-embedded socket can be made of gray cast iron HT20-40 or materials with equivalent mechanical properties.
4.4 Number of plug sealing rings: at least 2 on the insertion section and 1 on the conical surface. 4.5 The number of grooves (cement connection strength reinforcement grooves) on the shell and core tube of S-type sockets shall be at least 4 circles, and the groove depth shall not be less than 3mm4.6 The core tube of the semi-cast (SB type) socket must be seated on the shell step with the help of a supporting ring. 4.7 The bottom outlet of the fully cast (SB type) socket should be in the shape of a trumpet with a small top and a large bottom. 4.8 The transition cone angle of the plug must be consistent with the trumpet cone angle of the upper end of the same type of socket. 4.9 For the plug with welded straightening block, both ends of the straightening block must have an external chamfer of no more than 45°, and its outer diameter should be 3-4mm smaller than the inner diameter of the thick-walled casing.
4.10 There should be a vulcanized rubber seal ring at the contact point between the conical surface of the socket and the float, which is more than 0.6mm higher than the conical surface; if an embedded rubber seal ring is used, it should be more than 1.umm higher. 4.11 The thread of the plug connector should meet the requirements of GB9253.1. 4.12 The connection of the interface and connection at both ends of the S-type socket. a. For the socket with an outer diameter of less than 406.40mm, the threads at both ends should meet the requirements of GB9253.2; b. For the socket with an outer diameter of 406.40mm or more, the threads at both ends are not allowed to be processed, and the upper end of the smooth hoop (threadless coupling) should be able to ensure the insertion of the outer thread of the casing. The lower end should be able to be inserted into the coupling of the casing downhole. After insertion, the on-site electric welding should be carried out, and the fillet end weld should reach "
√. When the grade of the welded casing is higher than J-55, the casing needs to be replaced or preheated (155~200℃) and heat-insulated (buried in lime or wrapped with cotton rope) welding technology should be adopted. The socket should be welded on the ground in advance. 4.13 The surface paint should comply with the provisions of Taiwan SY5308, and the surface should be painted black. 4.14 The connector thread of the plug should be copper-plated or phosphated. 4.15 S-type sockets can be shipped after 7 days of cement curing, and can be lowered into the well after 28 days. 5 Test method
5.1 T-type socket load capacity test, the support ring is screwed into the casing coupling, and the bell mouth or lathe is used. The externally threaded short-circuit is screwed into the supporting ring, covered with a steel plate, and axially pressurized to the value in Table 3. The supporting ring shall not have any visible cracks or deformation. 5.2 Sealing ability test between plug and socket: Test the pressure with 20% engine oil to the value in Table 3 and stabilize the pressure for 3 minutes. 5.3 The float is maintained in 90℃ water towel and pressurized at 10MPa for 24 hours. If there is no softening or deformation, and the performance is based on the test and does not fall below the requirements of this article, it is allowed not to test.
