Dynamometer “DDIM-2”

The operating manual applies to “DDIM-2” dynamometer

(hereinafter referred to as the device) designed for operation at the

wellhead equipped with a sucker-rod pumping unit (SRPU) in oil and gas

fields. The device is explosion-proof designed (intrinsically safe circuit

type of protection) in accordance with the requirements of GOST 31610.0-

2014 (IEC 60079-0:2011), GOST 31610.11-2014 (IEC 60079-11.), GOST

31610:2011), and have 1Ex ib IIB T3 Gb Хexplosion proof mark.

“DDIM-2” is designed for indoor and outdoor installation in hazardous

areas where atmospheric explosives of IIA, IIB categories and T1, T2, T3

groups can form according to GOST R IEC 60079-20-1-2011 in the

operating temperature range from -40 ºC to +50 ºC. The device design is

comply with the assigned explosion proof mark, with the requirements of

GOST IEC 60079-14-2013 and other regulatory documents governing the

use of electrical equipment in hazardous areas.

The operating manual provide the details about technical

specifications of the device, delivery set, service life, storage and

manufacturer's guarantees, as well as other information about the device

used for the operation process.

Observe the requirements of the Federal norms and regulations in

the field of industrial safety "Safety rules in oil and gas industry"as well as

this manual, when operating, maintaining and repairing the device.

The device may only be operated by specially trained personnel

who have studied the operating documentation for the device, received the

relevant safety instructions and permission to work.

2. SAFE OPERATION GUIDELINES

2.1. General Provisions (regulatory framework)

The design of the wellhead equipment is to be approved by the

Russian Technical Surveillance Agency (RTSA).

Preparation of the well for tests should be conducted in accordance

with the requirements of the current Manual and internal guidelines

for maintaining and testing wells approved by the head of the

company.

Test equipment is to be operated according to the operating

instructions supplied with the equipment.

Measures for ensuring safety are regulated by labor protection

instructions for respective types of work approved by the

Company’s Department of Labour Protection and the Safety

Regulations in Oil and Gas Industry approved by the RTSA.

2.2. Requirements to Personnel

Well tests are to be carried out by individuals above 18 who have

secondary education and who are medically cleared for work.

Personnel are to take professional training followed by knowledge

checking and have a relevant permit category in accordance with

qualification requirements: not below category 5 for oil and gas

production operators; not below category 4 for well test operators.

Personnel are to be trained to work with test equipment.

2.3. Requirements to Test Objects

Pressure measurement and control of fluid level is carried out in oil

and gas producing wells of different operational modes (flowing, gas lift,

artificial lift, etc.), as well as in injection, intake, control and other wells

driven by a beam pumping unit of SKN series according to GOST 5866-

56, SKD according to GOST 5866-76, SKD according to OST 26-16-08-

87, including all the standard and similar foreign manufacture sizes.

Wells are to be tied and operated in accordance with the Safety

Regulations in Oil and Gas Industry.

When controlling the dynamogram, the rod string is to end with a

polished rod 16… 39 mm in diameter.

The polished rod is to be sealed with SUS1 or SUS2 gasket. The

rod and the beam pumping unit are to be connected with a clipping

of the wellhead rod of PSH type. The limits of the clipping

configuration are shown in Figure 1.

НЕ МЕНЕЕ 105 мм

Figure 1.

The pumping unit control station is to have a mode select switch

with the manual control option. The moving parts of the pumping

unit (the crank-conrod mechanism, the V-belt drive) are to be

properly fenced.

The service platform shall comply with the requirements of the

"Safety Rules in Oil and Gas Industry". Scheme of the platform is

shown in Figure 2.

If the height of the polished rod packing is low (up to 2 m above

ground level), portable platforms are to be used provided they

comply the above requirements.

3. BASIC SPECIFICATIONS
