Methodology of drilling mud development for penetration of unstable rocks containing clay minerals

Article preview

When developing drilling fluid formulations, first of all, the geological situation should be assessed, the mineral composition should be determined and the properties of the rocks to be drilled should be comprehensively studied.

Газообъемный экспресс-метод определения карбонатности аргиллитов

Article preview

Известно, что содержание кар­бонатных пород в аргиллитах влияет н a их устойчивость и поэтому мо­жет использоваться в качестве про­гнозирующего параметра при буре­нии неустойчивых, склонных к обру­шениям зон аргиллитов. Имеющие­ся химико-аналитические методы, оп­ределения карбонатов сложны и малопроизводительны ...

Application of hydrophobic emulsion for drilling through mudstones of the Exploration Formation of the Norilsk Region

Article preview

Well sinking in mudstones of the Exploration Formation is usually accompanied by collapse of well walls. This leads to high time consumption for wellbore development and re-drilling of collapsed intervals ...

Purification of flushing fluid from drilled rock

Article preview

The introduction of the KSSK complex in the Norilsk Integrated Exploration Expedition required the use of non-structural flushing fluids with low solid phase content, since small gaps between the core barrel and drill pipe, as well as between the borehole walls and drill pipes, increase the pressure in the injection line ...
