Application of oil-based drilling fluid in Longfeng Mountain area block
Compared with water-based drilling fluids,oil-based drilling fluids not only have better wellbore stability,inhibition,lubrication,temperature resistance,and pollution resistance,but also have better reservoir protection performance.During sliding drilling,they have largely solved the problems of drilling pressure and sticking,and have become an indispensable and important means for some deep wells,high-temperature wells,directional horizontal wells,and complex wells.The North 201 platform well is the first platform well of Northeast Oil and Gas Company,and it is also the first time that the Longfeng Mountain area block has adopted an oil-based drilling fluid system.This platform well has overcome multiple construction difficulties and created 13 block records.The article combines the construction situation of the platform well to describe the technical measures in terms of configuration,performance maintenance,for reference.
