In the oilfield development process, reservoir minute description plays a basic role.This article analysises geological characteristics of Liao He oilfield Huan 2-14-16 block of DalingHe reservoir, establishes a three-dimensional geological model, divises exploitation phase and studies in-depth each stage's mining characteristics, according to development process and characteristics carries on further research and discussion,studies distribution of remaining oil in the same time, carries on fine description of Huan 2-14-16 block DaLingHe reservoir,and provides scientific advices of comprehensive adjustment and potential seeking in the next step.This has important practical significance for Huan2-14-16 DaLingHe block reservoir development mode oil change, enhanced oil recovery level to achieve sustainable development of oil fields.This article takes detailed reservoir geological characteristics, the remaining oil distribution, regularity and control factors as the research objects, to promote the efficient development of oil fields and enhanced oil recovery and residual oil to provide detailed geological model for the target. The content mainly around reservoir fine geological characteristics, three-dimensional geological modeling found, development stage and characteristic, development effectiveness analysis and residual oil distribution in several ways。The main results are:1.Through detailed study of Huan 2-14-16 block DaLingHe reservoir geological characteristics, through the micro-structural characteristics, sedimentary facies, reservoir characteristics and hydrocarbon distribution and comprehensive evaluation to determine the reservoir type and its controlling factors combined with reservoir fluid properties, pressure and temperature on the block to re-estimate the oil and gas reserves, so as to achieve the fine geological reservoir description of the purpose.2. In understanding the tectonic graspeing fracture system premise, buiulds model in use of geological result directly. This block belongs to the old zone, the block also carried out a detailed interpretation, geological, tectonic and reservoir studies, and the block meets the conditions of modeling and establishes a three-dimensional geological model with the use of Schlumberger's Petrel2004 software.3. In deep understanding of the development process and the development features of the block, analysis of various of effects development, carries on detailed analysis of the effects of block development by production decline from the block, effect of water flooding, water conditions, oil production rate and other aspects evaluating the current Well adaptability, the use of oil wells and the utilization of reserves and identifying problems in block the development process.4. Through numerical simulation and remaining oil distribution study determines the block's development potential and gives scientific advices on the next step of the potential deployment and adjustion.The innovation of this paper are:(1)through the establishment of three-dimensional geological model, builds link and bridge for various disciplines such as seismic, logging, geological, and reservoir.We can analy effectiveness of various factors on the block development more intuitively;(2)takes fine analysis of the development of reservoir characteristics and development of reservoi effects to identify the key problems of restricting the block's development,and use numerical simulation to find out the remaining oil distribution, accurate analysis of the oil potential, to provide scientific advices of comprehensive adjustment and potential seeking in the next step.
