| The article takes detailed reservoir geological characteristics, the remaining oil distribution, regularity and control factors as the research objects, to promote the efficient development of Jin-25 block YuLou oil field 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 several ways.The main results are:1 Through 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 an the block to re-estimate the oil and gas reserves,so as to achieve the fine geological reservoir description of the purpose.2 The article carried out a detailed interpretation, geological, tectonic and reservoir studies, and in the article the block meets the conditions of modeling and establishes a three-dimensional geological model of Jin-25 block YuLou oil field.3 In-depth analysis of various of effect 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 is development potential and gives scientific advices on the next step of the potential deployment and adjustion. |
