Совершенствование организационно- технологических схем обращения с отходами бурения

Abstract

In the article the relevance is substantiated related to improving the organizational and technological schemes for handling of drilled cuttings of hydrocarbons of a polycomponent composition from the standpoint of improving the environmental safety of territories during the development and operation of oil and gas fields, as well as ensuring the industrial safety. Analysis of the existing drilled cuttings management systems is carried out, and the classification of their storage facilities is presented depending on the time, their location and on the waste management scheme to prevent flooding and waste spills due to emergencies. The requirements are given concerning the construction of temporary accumulators and sludge pits, as well as the conditions for classifying the waste management system as a pitless drilling method. The recommendations are proposed for choosing an accident-free organizational and technological scheme for handling of drilled cuttings, and measures to reduce the negative effect on the components of the environment during the accumulation and disposal of drilled cuttings. The features of accumulative drilling technology are considered, which provide for the accumulation of generated drilled cuttings in the temporary storage facilities with their subsequent processing, neutralization and (or) disposal without removal from the territory of the well construction/reconstruction site. The causes and consequences of emergency situations are presented. The implemented organizational and technological scheme of drilling waste management is presented using a logical and information model. Recommendations are given on the choice of an organizational and technological scheme for handling of drilled cuttings when improving the systems for managing the flow of drilled cuttings from the wells of hydrocarbons of the multicomponent composition, depending on the hazard class of drilled cuttings generated by the subsurface users, as well as the territories with environmental restrictions.
