| Abstract: | In accordance with the reservoir characteristics of central anticlinal belt in Jiangling Seg, this paper analyzes the factor of formation damage. Based on the study of salt resistance of the additives and compatibility to formation water, two kinds of drilling fluid and completion fluid system are developed. Both in the lab and in the field, the tests show that the damage of the two fluid systems to the reservoir is light. Ruturn permeabilities are both above 70 %, and skin factor is smaller. So the drilling fluid and completion fluid system can prevent the oil and gas formation from the damage effectively. |
