Application of Borehole Wall Stability Technology in Old Area of Zhongyuan Oilfield

Abstract:

The causes of borehole instability are mainly mechanical, chemical and engineering factors. By the analysis on drilling construction data of 2010, study was made on borehole wall stability technology in old area of Zhongyuan oilfield. Based on the problems in construction and the measures adopted, some suggestions were put forward for borehole wall stability in old area of Zhongyuan oilfield.
