Xifeng Oilfield XX District8Special Factors Of Low Permeability Reservoirs Stable

Xifeng Oilfield of Chang8special low permeability reservoirs located in northernShaanxi slope west. As the mining depth, the study area there are some production anddevelopment issues that affect the long-term and stable development of the reservoir, so bystudying its geology, fluid properties and other characteristics, and the study area of staticand dynamic data analysis to identify the impact of the study area the main factors and stable,and suitable for the study area to develop the current stable production measures and proposeappropriate comprehensive measures to achieve stable production development purposes.①The study area of Chang8Reservoir delta depositional systems, mainly developedunderwater distributary channel delta front sedimentary microfacies; poor reservoirproperties, strong heterogeneity; moderate-Weak Min, moderate acid sensitivity, weak-nospeed-sensitive.②The study area of Chang8reservoir studies to develop water-based, reservoir wellproduction is relatively high, the production decline is relatively small, the formation energylevels remain relatively stable oil recovery can basically meet the standard recovery.③Through the development of reservoir characteristics and regularity of results ofChang8ultra-low permeability reservoir development Countermeasures widespread problem,according to work out a reasonable and stable development of countermeasures to study wellarea of production parameters to be adjusted to achieve stable production purposes.④Based on sound and stable development of technology policy research, based on theexisting well pattern, injection systems, and stable sound reasonable countermeasures;through the deployment of encryption adjusted well to enhance oil recovery; strengthengovernance sectional injection wells to increase water level of driving, so as to improve theeffect of oilfield development to ensure sustained and stable development of the reservoir.
