Detailed Reservoir Description For MU-118Block

Detailed reservoir description is an important foundation to find out the distribution ofremaining oil, explore the more potential of developed reservoir, and continuouslyimproveing of recovery efficiency. It is also the key to keep the development of the oilfieldstable, in the medium-late term of oilfield exploitationMU-118block has been in the late high water stage through35years of development. It ishard to stable oil production and water control, the low level of recovery, the potentialdirection is unknown.It is a serious impact on the effect of block development. Against theactual development of the contradictions and geological features, stratigraphy, sedimentology,and development geology theory as a guide, do the formation of fine contrast with dividedmicrofacies research, logging the second explained, reservoir characteristics,three-dimensional geological model of the establishment of detailed reservoir studies.Work through the MU-118block of detailed reservoir description and understanding ofreservoir characteristics of the constructed system, the distribution of sand bodies and themicrofacies plane and space distribution; Understanding the distribution of reservoirparameters of the heterogeneity of the reservoir characteristics and the implementation ofgeological reserves; Using Jason software and create high-precision three-dimensionalgeological model, clear and intuitive way to show the characteristics of each reservoir,provides the basis for the next step for the formulation of development programs.From researching on the subject, getting a clearer understanding of the block reservoircharacteristics, straighten out the relationship between injection and production, and clearlythe potential direction. Potential analysis and evaluation of the reservoir block. to maketargeted programs and recommendations about proposed water injection adjustment,measurestapping the potential, capacity to deploy, and fully tap the resource potential. All of the workprovided technical support for long-term stable and long-term development of the block.
