| description | The relevance of the discussed issue is caused by the fact that more than 70 % of wells at the FFC «LUKOIL-PERM» fields are repaired because of asphaltenosmoloparaffin sediments. At present, in the conditions of a variety of compositions and properties of well production there are no strictly defined technologies for complete removal of asphaltenosmoloparaffin sediments from the walls of downhole equipment. Comprehensive selection of reagents and development of technologies for cleaning deep-pumping equipment from asphaltenosmoloparaffin sediments are the priority tasks for the FFC «LUKOIL-PERM» fields. This can reduce the time and economic costs. The main aim of the study is to develop a comprehensive method for selecting asphaltenosmoloparaffin deposition removal technology in mechanized oil wells. The methods. The work was performed in accordance with standard and developed methods for carrying out experimental studies of the dissolving and dispersing power of reagents relative to asphaltenosmoloparaffin sediments (studying the asphaltenosmoloparaffin sediments removal from surfaces simulating downhole equipment, investigation of adsorption and desorption of asphaltenosmoloparaffin sediments particles in downhole equipment). The results. The authors have determined the main methods of selecting the technology for fighting with asphaltenosmoloparaffin sediments in wells. There are substances that increase the washing capacity and the effectiveness of the composition. The authors developed the block diagram of a reagent selection for controlling asphaltenosmoloparaffin sediments. Its use will increase the efficiency of cleaning downhole equipment. The paper introduces the classification of success of operations. Based on this classification the maximum periods of the interclear period were obtained, depending on the between-repair period for various wells drilled in the flow rate. Using the developed methodology will allow calculating the maximum duration of the well with high accuracy, preventing failure, shutting down wells and unscheduled repairs. |
