Experimental Study on Reservoir Damage by High Mineralization Drilling Fluids
To evaluate the damage caused by high mineralization drilling fluids to the reservoir,combined with the actual production of oil fields,through the compatibility evaluation experiment of drilling fluids and formation water and the adaptability evaluation experiment of drilling fluids and reservoirs,the impact of high mineralization drilling fluids on the reservoir during drilling was studied.The results show that low-temperature drilling fluids entering the reservoir will scale with formation water,forming scale in the near-well zone of oil and water wells,wellbore,or production equipment,thereby hindering fluid flow and reducing production efficiency.
