Hard to recovered reserves evaluation and development effect of Jin 100 fault block in Huanxiling oilfield
-
Abstract
Aiming at the development problems of Jin 100 fault block in Huanxiling oilfield, the 3D seismic reinterpretation has been carried out. In combination with well test and production test data, the block structure and beneficial hydrocarbon prospective areas have been further confirmed. By using drilling data, the sand body distribution regularity in vertical and horizontal direction has been studied. Through sedimentary facies study and stratigraphy correlation, the reservoir distribution and oil layers development have been predicted, and then the oil reservoir type and oil layers productivity have been determined. According to evaluation results, two development wells should be deployed. After pilot production, good develoment effect has been achieved.
