Research on Methods of Improving Historical Fitting Accuracy in Transitional Zone Area

Abstract

The transitional zone of X Oilfield has a large development area, many oil and water wells, and the historical fitting accuracy is relatively low. The historical fitting accuracy of single wells in the whole area is only 62%. With the needs of oilfield development, it is inevitable to improve the historical fitting accuracy in the transitional zone. Therefore, this paper studies the method of improving the historical fitting accuracy in the 350m transitional zone of X Oilfield, and the historical fitting accuracy has increased by 13 percentage points.
