The Research Of Fine Reservoir Description For Leaves107, Ning50Block

Fine reservoir description is a basic research work for the implementationof the geology; it plays a very important role for reservoir structure, reservoirproperties, preparation of reservoir adjustment scheme.Based on the careful combing and absorbing previous research results, reservoir description for107left, Ning50fault block were carried out. In the study area through the fine stratigraphic division and contrast,3D seismic interpretation, the further implementation of the research area of the whole structure system and the internal micro structure; at the same time found Ning50blocksouth of the micro structure, and has carried on the exploratory drilling, obtained remarkable result, recognize the fault block south of late50with the spreading edge and increasing storage potential.Through the study on the sedimentary environment, sedimentary background, has divided the sedimentary facies and microfacies study area, wherein theupper delta plain sand sediments, Dongying group is meandering river deposition. Based on the well, seismic combination, establish the structure and attributemodel of the study area, showing the reservoir geological morphology in three-dimensional space, realize the digitization and visualization of reservoir. By logging data re-processing, re-interpreted, established a new interpretation charts,calibrated with oil-bearing and oil abundance of the reservoir, the use of new logging interpretation results were upgraded109.6meters/42layers,/19layer51.1meters downgrade.Based on the review of reservoir, geological reserves in the study area was recalculated, and Ning50fault block in numerical simulation work, study on oil-water movement, has been clear about the reservoir remaining oil distribution and potential of; studies show that the remaining oil concentrated in largereserves of main sand body and the main sand body is still the main objectof late potential. The effect of carrying out block two main measures analysis,that left107block of early small dose profile control in block50, Ning latehigh dose depth of flooding is feasible, the next step can insist to continue topromote. On the basis of previous research results, formulate the developmentstrategy of the late two fault block.
