随着油田开发的不断深入,地下油水分布越来越复杂,加上大庆外围低渗透油田储层发育较差,砂体分布零散,给油田动态分析和动态调整造成一定困难。本文在结合油田生产实际需要的基础上,有效地利用油水井压力监测及注入剖面、产液剖面等资料,研究油层动用状况和剩余油潜力分布,提高油田动态分析的正确性,检验注水井浅调剖效果,指导油田注水结构、产液结构和油田动态调整,为水井细分,以及油水井压裂、酸化、堵水等措施挖潜提供依据,从而达到改善油田开发效果、提高经济效益的目的。
With the deepening of oilfield development, the distribution of oil and water in underground is more and more complicated. In addition, the reservoirs in the peripheral low permeability oilfield in Daqing are poorly developed and the sand bodies are scattered. This makes it difficult for dynamic analysis and dynamic adjustment of the oilfield. Based on the actual needs of oilfield production, based on the actual needs of oilfield production, effective use of oil and water well pressure monitoring and injection profile, production profile and other data to study the reservoir utilization and residual oil potential distribution, improve the correctness of dynamic analysis of the oil field, The profile control effect guides the oilfield water injection structure, liquid production structure and dynamic adjustment of the oilfield to provide basis for subdivision of water wells and tapping potential of fracturing, acidification and water blocking of oil and water wells so as to achieve the purpose of improving the oilfield development effect and improving economic benefits .
