Improvement of Coring Technology in Deep Wells
To increase production, it is possible to commission new hydrocarbon deposits, or conduct exploration work in existing wells, and obtain hydrocarbon reserves from the Pz and Kv Paleozoic basement. In order to achieve this, it is necessary to conduct core sampling from the Paleozoic basement to study the geological characteristics of the field. The main purpose of each coring operation from all types of wells is to obtain direct information about the rocks that are comprised of the objects of interest in the fields, which is necessary for solving a complex of problems of prospecting, exploration and production of hydrocarbons. Core sampling in Paleozoic sediments is always a very complex technological operation and leads to an increase in the number of trips and an increase in the time for this type of work (coring). The authors have developed a new type of a new type of lubricant, which should reduce core jamming, both in the KRC layout and in the disposable ground strikers used. The advantages of the proposed lubricant: facilitates core lifting; increases the length of the voyage in the destroyed rock; extends the service life of equipment lowered into the face.
