Wyznaczenie najlepszego miejsca montażu urządzeń technologicznych na podwoziu pojazdów naprawczych na polach naftowych

Abstract

Currently, it is impossible to imagine the repair and drilling of any well without the use of modern mobile equipment. With technological progress, not only new development technologies in the branch of field exploitation appear, but also new equipment with which oil and gas wells are repaired and reconstructed. Today, oil production is mainly carried out by the operation of wells without a pumping derrick, which makes it possible to sharply reduce the cost of metal and funds. Operations of downhole equipment lifting and tripping in a well are carried out using self-propelled mobile units representing tracked or wheeled transport vehicles on which a derrick (mast) with a winch, transmission and hoisting system is mounted. Lifting units are equipped with a mechanism for raising the mast to the working position and lowering it to the transport position. Installations with a lifting capacity of up to 32 tons inclusive are designed for lifting operations during routine underground repair of wells, whereas over 32 tons minimal lift capacity are required during major repairs and well development. The mobile unit is subjected to oscillatory movements both during transportation along unpaved, semi - destroyed, muddy and snow-covered roads to the well (for development, repair), and during well drilling. The frequency of the oscillating movement depends on the state of the uneven road. The unevenness of the road is expressed by spectral functions. In this case, both the chassis and the body of the mobile unit, as well as the technological equipment located on it, are subjected to oscillatory movements. As a result, technological equipment, as well as devices and equipment located on it, lose their accuracy, which leads to accidents both during drilling and during operation. Therefore, in order to minimize the influence of oscillatory movements on the operability of technological equipment, a technique was developed for technological equipment positioning on the chassis of a mobile unit at an optimal scheme according to the proposed method.
