1.1.1 The system is designed to register and transmit to SwB controller current parameters ob-tained by the DhU and provided in Table 1.
1.1.2 Set of conventional signs of SPT designs is provided in Table 1.
Various designs are designated by the following indices depending on material and dimensions of DhU:
SS – stainless steel housing;
C – corrosion-resistant coating of housing;
115L – length of motor winding heat converter, 115 mm;
95 – outer diameter of gage, 95 mm;
S – design made for Surgutneftegaz company.
Standard design of TMS (no indices) shall control parameters as follows: temperature of reser-voir fluid (0 to +150 С), temperature in motor base (0 to +200 С), oil pressure in motor (0 to 40 MPa), insulation resistance in circuit transformer-cable-motor and designed for operation of DhU at not more than +150 С of environment.
SPT-2-V – telemetry system of second modification with control of reservoir fluid (0 to +150 С), motor base temperature (0 to +200 С), pressure of motor fluid (0 to 40 MPa), vibration in three dimensions and designed to operate DhU at temperature of environment not more than +150 С;
SPT-2-60-T-M–K – downhole telemetry system of second modification with temperature con-trol of reservoir fluid (0 to +155 С), motor base temperature (0 to +200 С), motor fluid pressure (0 to 60 MPa), with corrosion-resistant coating and designed to operate DhU at temperature of environment not more than +155 С.
