| In April2008,Ning51Wells had in20.91t/d long industrial oil flow in chang2oil test in Ningxian, the early production of the oil is6.2t/d, water cut7.6%; It showed the block2reservoir had a good development prospects. As of October2011, ning51area, a total of51Wells drilled well, average drilling in oil layer of3.4m,37wells had been put into production Wells initial average single well oil was1.41, water cut72.1%, the average single well oil1.2t, water cut of41.8%.13betting water Wells, injection, on average12.0m3. For better exploitation of the block, In this paper, based on chang2reservoir geological characteristics in Ning51district, reservoir geological model is established, and we had research on the development and production of dynamic analysis, dynamic characteristics analysis of water breakthrough, the actual pressure data analysis and evaluation of water drive control degree and water flooding effect evaluation, by using reservoir numerical simulation mode to study ning51reservoir remaining oil distribution features, and make the technical countermeasures to improve development effect. |
