STUDY OF HUAN 127 LOTUS REMAINING OIL DISTRIBUTION AND POTENTIAL COUNTERMEASURES

Huan 127 Lotus heavy oil reservoir has been the development later period of steam stimulation,the block close to the edge of the abandoned.Since 2005,based on the principle of oilfield late development,the detailed reservoir geological studies were carried out.The distribution of small layer remaining oil was described by using reservoir engineering methods,and the methods of improving development effect were put forward by sidetracking extended reach wellbore and horizontal well,and good results had been achieved.
