对油气田储量和采收率的新认识

容积法探明地质储量管理方式弊多利少，探明地质储量的计算不可避免地存在着误差，开发过程中又很少考虑其变化，其采收率与油气藏地质特征往往不相符、横向可比性较差，不适应当前市场经济环境和国际接轨的要求。而在一定条件下，油气田动态地质储量可靠、实用，其采收率符合油气藏实际特征、横向可比性强，既涉及油气藏的地质静态和动态特征，又考虑到经济因素，根据大量的动态资料确定的可采储量，不仅准确程度较高、符合油气藏实际地质特征、突出了经济价值，而且适应当前市场经济及国际接轨的要求。因此，应淡化探明地质储量和采收率，重视可采储量。

RE-UNDERSTANDING RESERVES AND RECOVERY FACTOR OF OIL/GAS FIELDS

The reserves management with geological reserv es determined by the volumetric method has more disadvantages than advantages. T he calculation of the certified geological reserves has unavoidable errors. The reserves change is less considered in production, which makes the recovery facto r not fitting the geological features of the oil/gas reservoir and the lateral c orrelation poor. So it is not suitable for the recent market economy environment and the requirements to meet the international practice. Under certain conditio ns, the dynamic geological reserves of oil/gas fields are reliable and practical . Its recovery factor fits the real features of the oil/gas reservoir. The later al correlation is good. The dynamic geological reserves consider not only the st atic and dynamic geological features of the oil/gas reservoir but also the econo mic factors. The recoverable reserves determined by large dynamic data not only have high accuracy, fit the real geological features of the oil/gas reservoir, a nd stress the economic value but also meet the requirements of the market econom y and the international practice. Therefore, more attention should be paid to th e recoverable reserves, and the certified geological reserves and the recovery f actor should be used less and less.
