摘　　要：汪家屯气田是大庆外围试采较早、整装的中浅层气田,主要开采泉头组三、四段的天然气储层,气田单井产量低、井控储量小、开采效益差、动用程度较低。为加快气田开发,明确气田潜力,一方面,通过加深区域地质认识,结合开发特征,预测气田潜力区,部署加密井;另一方面,通过建立气水层解释标准,进行老井潜力评价,制定老井挖潜措施。新老井挖潜措施取得了较好效果,加深了气田开发地质认识,提高了气田采收率。Wangjiatun Gasfield is a middle-shallowlayer gasfield characterized by earlier production test and uncompartmentalized configuration among Daqing peripheral oilfields. The main produced reservoirs are No. 3 ＆ 4 Members of Quan Formation, the production of individual well is rather low, the controlled reserves are limited, the exploiting benefit is poor and the developed degree is rather lower. In order to speed up the development and make clear of the gasfield potentials, on the one hand, the potential blocks of the gasfield are predicted and the infilling wells are deployed by means of deepening regional geological understandings and integrating with the development characteristics; on the other hand, through the establishment of interpreting standards of gas and water layers, the potentials of the old wells are evaluated and moreover the contermeasures are determined. In the end, the much better results are achieved, the understandings of the gasfield development geology are deepened, the recovery factor is enhanced.
