Evaluation Of The Effect Of Oilfield Development SZ36-1 Water Flooding

Offshore oilfield development starts late in China. SY/T6219-1996,The oilfield development level grading, issued in1996, which is only for onshore oilfield.Restricted by the development environment, offshore oilfield waste conditions are significant differences with onshore oilfield waste conditions.Using the industry standard is not applicable to evaluate the effect of offshore oilfield waterflooding development effect. Therefore, how to establish a set of evaluation system and evaluation standards for offshore oilfield development effect,according to the characteristics of marine oil field development, correct and reasonable evaluation of the effect the development of the offshore oil field has important theoretical significance and practical value.Taking SZ36-1oilfield as an example, in view of the offshore oil field development effect evaluation technology present situation and existing problems, and mainly carried out the following research work and obtained the corresponding results1)On the basis of analysing and evaluating the adaptability of the industry standard to evaluate the offshore oilfield development,we established a hierarchy of index system suitable for the offshore reservoir development evaluation at first time;2)Key development effect evaluation index calculation methods,which were suitable for the Bohai ordinary heavy oil field, were studied to obtain the variation of the critical development impact indicators;3)We established indicators of the five levels of the standard for key development effect evaluation index which were suitable for the Bohai ordinary heavy oil field, based on the indicator of the theoretical variation, Combined together the former ministerial industry standards, the achievements of early water injection development effect evaluation research and the actual dynamic of typical oilfield;4)We combined SZ36-1oilfield reservoir characteristics and development of dynamic to analyzes the effect of the development of Bohai typical heavy oilfield, then,analyzed the key indicators of the actual and theoretical reasons for the differences, and proposed the development of technology policy.
