全压力史拟合法的应用

油田在开发过程中常常遇到稠油、低渗油藏，而多相流动等更进一步降低了储层的渗注能力。对这类井进行压力测试，深沉由于测试时间短、探测半径过小，无法获取足够的地层信息。鉴于此，提出了全压力史拟合方法，即细查全井生产动态资料，结合实际经验，以软件进行产量校正，从而建立完整的符合生产实际的全井产量史进行整体拟合分析及精细解释。对于低渗、超低渗油藏，该方法能够从较短时间的测试资料中获取足够的地层信息，给开发生

Application of All Pressure History Match Approach

In the process of oilfield development, viscous and low permeability oil reservoir is very popular, while multiphase flow further decreases percolation flow capacity of the reservoir,pressure test to these wells is often impossible to get enough reservoir information due to short test time and very small radius of investigation. For this purpose, this paper puts forward an all pressure history match approach, that is to carefully examine dynamic production data of whole well, combined with actual experience, correct the production rate with the software, therefore to create a complete whole well production history corresponding to productive reality for integral match, analysis and fine interpretation. To low permeability and extremely low permeability reservoirs, this approach is able to get enough reservoir information in very short time and to provide a guidance to oilfield development.
