Development and prospects of logging evaluation technologies for reservoirs in Shengli Oilfield
摘要
Abstract
Shengli Oilfield has abundant oil and gas resources,with multiple types of reservoirs,and logging evaluation plays an es-sential role in exploration and development.The development history and the characteristics of logging evaluation technologies for reservoirs were systematically reviewed to celebrate the institute's 60th birthday.Summarizing experience and predicting the future have positive significance for the development and application in the professional logging field.A series of mature evaluation tech-nologies formed in three types of reservoirs,including conventional sandstone reservoirs,complex reservoirs,and unconventional shale reservoirs,were systematically summarized according to the characteristics and evaluation difficulties of reservoirs.For con-ventional sandstone reservoirs,a highly applicable identification technology for oil layers was systematically developed,and an in-novative method for establishing electrical standards constrained by the lower limits of lithology and oil potential was developed un-der multi-layer joint testing conditions.In addition,a pioneering logging modeling technology was proposed based on different dia-genetic zones.Various technologies were developed for complex reservoirs,including logging identification of sandstone lithology in steep slope zones,effectiveness evaluation of low-permeability sandstone reservoirs,and identification and evaluation of oil lay-ers with low resistivity.For unconventional shale reservoirs,a logging evaluation technology of reservoir parameters was prelimi-narily developed to evaluate the storage properties and oil potential mainly based on two-dimensional nuclear magnetic resonance experiments.These logging evaluation technologies for different types of reservoirs reflected the combination of wellbore data and geological understanding,as well as the integration of rock physics and logging models,and they demonstrated the ability of log-ging to serve geology and reservoirs and achieved good application results.In the future,the remaining resources will mainly be dis-tributed in hidden oil and gas reservoirs and deep layers.In order to meet the needs of exploration and development,it is necessary to strengthen the analysis of experimental data,gas logging,and testing production data,combine logging evaluation and geology,intensify the application of new logging technologies such as logging while drilling,imaging,and nuclear magnetic resonance,carry out comprehensive research and evaluation,and expand the evaluation and prediction of production capacity of oil layers from the perspective of evaluation objectives.Moreover,it is necessary to fully rely on expert experience to select samples and deepen the application of big data/artificial intelligence on the basis of conventional technologies,which will definitely achieve good results.关键词
