IMPROVING THE METHOD OF SELECTING BUFFER TO IMPROVE THE QUALITY OF WELL ANCHORING WITH THE USE HYDROCARBON-BASED DRILLING FLUID

Currently, when cementing casing strings, various formulations of buffer fluids are used, the choice of which is based on laboratory testing of its compatibility with specific drilling and grouting solutions. The development of market relations evolutionarily pushed manufacturers to obtain and use the most efficient, durable materials and technologies that meet the requirements of ISO 13500:2008 [11], ISO 10426-2:2003(R) [12].In foreign and Russian practice, leading oil and gas companies use integrated quality management systems. However, due to the influence of a number of socio-economic factors, there has been a sharp rise in the cost and reduction in the production of components, along with a continuous increase in the need for efficient materials in many industries. The use of components produced by domestic enterprises in industrial volumes makes them deficit-free, and in terms of price quite affordable and competitive raw materials [6].«RN-BashNIPIneft» LLC together with the «USPTU has developed a methodology to establish uniform requirements for the evaluation of buffer fluids for hydrocarbon-based drilling fluids when cementing casing strings. The methodological basis for achieving this goal is the concept of a systematic approach in the quality management of buffer fluids [8].
