为最大程度减缓钻关对油田开发的影响,以及为今后水井钻关提供指导,本论文根据某区块南屯组油层储层渗透率差异较大,断层发育的地质特点和各井组吸水状况及开采程度不一、地下动态变化大、压力分布不均衡的实际情况,在应用精细地质研究成果基础上,综合动态、测试资料研究了钻关水井压力变化的规律、影响因素及对周围油井产量递减的影响程度,并确定了不同压降特征水井的钻关时机以及加密调整后钻关水井的注水调整思路。
In order to minimize the impact of drilling off on oilfield development and to provide guidance for drilling in the future, according to the different permeability of reservoir in Nantun Formation in a certain block, geological features of fault development and water absorption of each well group Based on the results of fine geology research, based on the comprehensive dynamic and test data, the law of pressure variation in drilling well and its influencing factors and the influence on the production of surrounding oil wells Decreasing degree of influence and determining the timing of drilling and closing of wells with different pressure drop characteristics and the idea of adjusting the water injection of the drilled wells after the encryption adjustment.
