【摘要】：低渗透油藏储量丰富,天然物性差,开发难度大,开采程度低。合理的井网形式及井网参数可有效改善低渗透油藏的开发效果。合理的开发井网研究一直是油田开发方案中非常关键的课题,它是确保油田持续进行生产和油田企业实现经济效益的重要技术。开发井网系统是复杂动态的油田开发系统的子系统,它由各个单井共同组成。目前低渗透油田开发井网系统优化遇到需要折中考虑的问题：从油田的地质特点和开发经济效益出发,人们普遍认为只有采用较小的井距和较大的井网密度,才能达到理想的开发效果,可这样会导致钻井数增加、投入成本提。因此,研究井网的适应性,选择合理的井网形式及井网参数,成为经济有效开发低渗透油藏的关键问题之一。本文以靖安油田虎狼峁区长6开发研究区为研究对象应用实验室实验数据及录井、测井等资料了解清楚长6油藏的构造特征、储层特征、流体特征、油藏类型及原始驱动压力类型等；在了解该地区地质和流体特征的基础上,以井区发展历程为参考对油田开发特征、油藏注水开发效果加以评价；以上两部分内容为依据,从开发方式和井网部署两方面入手进行针对长6井区的井网改造前后不同形式井网、井网密度以及井距合理性的研究。
[Abstract]:Low permeability reservoirs are rich in reserves, poor in physical properties, difficult in development and low in degree of exploitation. Reasonable well pattern and well pattern parameters can effectively improve the development effect of low permeability reservoir. Reasonable well pattern research has always been a key issue in oilfield development scheme. It is an important technology to ensure the continuous production of oil field and the realization of economic benefits of oil field enterprises. Development well pattern system is a subsystem of complex dynamic oilfield development system, which is composed of each single well. At present, the optimization of development well pattern in low permeability oil field meets some problems that need to be considered in the middle. According to the geological characteristics of oil field and the economic benefit of development, it is generally believed that only small well spacing and larger well pattern density can be adopted. In order to achieve the ideal development effect, it can lead to the increase of drilling number and the increase of input cost. Therefore, to study the adaptability of well pattern and select reasonable well pattern form and well pattern parameters is one of the key problems in economic and effective development of low permeability reservoirs. In this paper, taking the development and research area of Hulangmao-Chang 6 in Jingan Oilfield as the research object, using laboratory experimental data and logging and logging data to understand clearly the structural characteristics, reservoir characteristics and fluid characteristics of Chang 6 reservoir. Reservoir type and original driving pressure type, on the basis of understanding the geological and fluid characteristics of the area, taking the development history of the well area as a reference to evaluate the oil field development characteristics, reservoir water injection development effect, the above two parts as the basis, From two aspects of development mode and well pattern arrangement, this paper studies the rationality of well pattern, well density and well spacing in Chang6 well area before and after well pattern reformation.
