复杂断块油藏溶解气可采储量研究方法优选

优选出适合复杂断块油藏地质特征的溶解气可采储量的研究方法十分必要，为此，在对东濮凹陷复杂断块油藏地质特征总结分析的基础上，对中原油田复杂断块油藏溶解气的可采储量进行了研究。以复杂断块——中老三块油藏溶解气可采储量标定为实例，用多种方法计算、评价其可采储量，优选采出程度法作为标定方法。进一步系统归纳总结了适合不同类型、处于不同开发阶段的油藏溶解气可采储量的研究方法，优选出适合复杂断块油藏溶解气可采储量标定的方法，对国内同类油藏溶解气的可采储量标定具有指导意义。

Optimum calibration method of the recoverable reserves of solution gas in the oil in complex fault blocks

It is necessary to optimize the calibration method suit-able for the recoverable reserves of solution gas in the oil reservoirs in complex fault blocks. For this reason, on the basis of analyzing the geological features of oil reservoirs in complex fault blocks in Dongpu Sag, this paper studies the recoverable reserves of solution gas in the oil in complex fault blocks. Taking Wenzhonglaosan block as an example, it gives calibration more ways for solution gas in oil reservoirs, evaluate recoverable reserves, and takes optimum recovery percent of reserve as calibration method. Then it summarizes the calibration method suitable for recoverable reservoirs oil reservoirs in different developing phases and in different oil types. It optimizes the calibration method suitable for the recoverable reserves in complex fault blocks with consideration of the practices in Zhongyuan oilfield. This method offers instructive meanings lor calibration of recoverable reserves of the same kind of solution gas in the oil reservoirs inland.
