Teleinspection of oil&gas wells

As is known, for maintenance of efficiency (serviceability) of chinks, their regular and versatile researches directed on reception of an as much as possible - trustworthy information about a condition not only the chink, but also a productive layer as a whole are necessary.

For today teleinspection is good addition to geophysical methods of research of chinks, and at use corresponding (already available or developed) technologies allows to supervise visually set of the factors influencing a condition of development of oil-and-gas deposits. What are we given with teleinspection? First of all is a visual definition of the reasons which have entailed behind self decrease debet obtaining or reception of a delivery chink. Traditional methods of definition of character of complications, for example - application of a lead seal for definition of character and a configuration of the extraneous subject which is taking place in a chink, assume repeated use of up-down operations, however frequently, information the given method is reduced to zero. Using the teleinspection, the extraneous subject taking place in a chink can be found out visually and, thus, operatively to make catching works with positive result. By means of teleinspection, it is possible to determine visually, what phases act from each productive horizon, to see in what condition a zone of punching and whether there is it in the necessary intervals of depths. Obtaining and delivery chinks during their major overhaul, are surveyed, in particular, for revealing defects of an operational column and definition of their coordinates with the purpose of decision-making on a way of repair of a chink. Other helpful information received at carrying out of teleinspection, can be detection infiltration subsoil waters for the lack of tightness of a column in an interval of water horizons, definition of the current static level in a chink, etc. At last, using teleinspection, it is possible, and in a mode of real time visually to definedetermine quality of those or other works carried out in a chink.

Small diameter of modern videocameras - as a rule, 42 mm - allows to use them in the working chinks which are taking place under pressure, lowering them through established standard antiouter equipment. It makes possible inspection of inwardness of an operational column in the chinks which are taking place in work.

For performance of works on teleinspection of chinks by depth up to 3500 m system STS-3500 with one-foreshortening or two-foreshortening the chamber is used. The system provides transfer of the color videoimage to real time.

Delivery of geophysical devices

The means of delivery developed recently in Joint-Stock Company TARIS on a horizontal site of a chink devices including videocameras, allow to carry out inspection not only vertical trunks of chinks, but also chinks with inclined and horizontal sites.

The system of the supplier weels for transportation of the geophysical equipment horizontal sites of oil and gas chinks will consist of the transport module working in a chink and a post of management, connected to the geophysical lift.

The supplier is connected to typical threevein to a geophysical cable through the standard tip located in a tail part. Through the similar tip located at a forward end face, to the supplier the sheaf of geophysical devices is connected. Descent{release} of the supplier and devices in a chink is made on column NKT, and after an output from NKT - on an operational column, up to a level on which a corner of an inclination of a chink allows to continue descent under a body weight (45°-55 °). For continuation of descent the operator actuates system of draft of the transport module. There is a disclosing levers of the supplier on which ends driving wheels are located. At switching-off by the operator of a voltage, levers of the supplier develop, and the supplier with devices is taken from a chink by means of the geophysical lift.

Carotage geophysical lifts

Carotage geophysical lifts of a series of the personal computer of manufacture of Joint-Stock Company " TARIS " are intended for carrying out up-down operations with wells devices at geophysical researches of chinks.

The basic distinctive feature of the given products is the electric drive created with application of a modern frequency regulator that provides a wide range of regulation of speed of rise and smoothness of a course on the set speed, allows to make management of the lift of more simple in comparison with the classical circuit of a drive from the engine of the base automobile. Same purpose is served also with an electric drive corrector stacking of a cable.

Besides there is an opportunity of management of the lift with the help of a personal computer that allows to integrate it with the modern research equipment.

The whole complex of constructive measures is directed on the decision of a problem of electromagnetic compatibility of a frequency regulator with the peripheral equipment that allows to avoid occurrence of handicapes.

The important advantage is also application of a compact unattended collector (the rotating contact device) with the minimal transitive resistance.

System of protection of internal area of a welded joint

On the basis of robot S-200 and the complete set pakers it is developed and the System of protection of internal area of a welded joint of oil pipelines in diameter of 273-530 mm mounted from pipes with an internal factory covering in field conditions " is used "

The system is intended for protection of a welded joint of pipes in a zone free from a factory covering, at construction of oil pipelines, at an ambient temperature from-30°C up to +40°С.

At work on protection of internal area of a welded joint in the pipeline the robot which, moving on a pipe, carries out transfer of the videoimage of its internal surface on the monitor of the operator is entered and carries out various operations with the help of the tool fixed on the day off to a shaft of the device of milling. Simultaneously to the robot can be attach paker, intended for installation of a bandage.

Pull a cable in dukers

One of last development of Joint-Stock Company TARIS is " self-propelled cable puller" which is intended for stretch a cable in pipelines (dukers) by diameter from 219 mm. Further the given cable can be used for carrying out various diagnostic and procleaning works.

At work inside of the pipeline the transport module to which back hook the cable is fastened is entered. After inclusion of a traction drive the module begins independent movement on the pipeline, carrying away for itself a cable.

The transport module represents all-wheel drive a four-wheel vehicle. Wheels of the module are resulted in rotation by two motors - reducers of the direct current eating from a set of lead storage batteries.
