Application Of Logging Data In The Development Of High Permeability Reservoir

Currently, water injection is the main development mode in each big oilfield.With the long time of water flooding, worse formation heterogeneity and ineffectivecirculation phenomenon will further increase the difficulty of elevating the recoveryrate. The application of new technologies, such as polymer flooding, threecomponents flooding oil and microbial flooding in the experiment of oil recoverymakes injected fluid more complex and meantime changes the formationparameters. Complex development form provides a wider space for the applicationof logging data.With the development of new production technology, complex changes happen,formation fluid properties of downhole tools are more complicated, variousreperforation, water plugging, fracturing, acidizing wells yield water controlmeasures to gradually increase, the contradiction of oilfield development in theincreasingly prominent, especially the two or three classes in high permeabilityreservoir, there are three the phenomenon of high moisture content, high residualoil, high mining difficulty. Facing with such a severe form of development, loganalysts concentrated their attention to the way to make full use of the logging dataand solve the contradictions in the development. Effective means of how to use thecontradiction in the development of diagnostic logging data and inspection oflogging data, the development of severe forms to logging technology has broughtchallenge and opportunity of development, logging technology in solving thecontinuous development and improvement process of development of thecontradiction. With some practical problems encountered in the development ofthe oilfield, the well logging data as the basis, to analyze and evaluate the variousproblems encountered in the process of oilfield development in high permeabilityreservoir in oil and water wells combined with geological static data and dynamicinformation of production, embodies the value of the application of testing data inhigh permeability reservoir development in conflict analysis and resolution in theprocess of.Along with the change of injected fluid, the contradiction of oilfielddevelopment are more diverse, there are a lot of, practical problems encounteredin the process of oilfield development in high permeability reservoir in such as: takeup the hole, water plugging the well stimulation, need to measure whether to aspecified location verification, need to evaluate the specific measures of how toreduce the effect; invalid inefficient circulation, improve oil displacement efficiencyetc.This paper mainly in Lamadian Oilfield as an example on logging data in thesolution of high permeability reservoir development of practical application problems: at present, injection of more than90%wells are stratified injection way,layered into the interlayer pressure difference will lead to the damage of casing,into the alkali liquid in oil and water wells three yuan pipe corrosion phenomenon ofcolumn scaling, serious, appear casing deformation, casing damage phenomenon.Electromagnetic defect detection logging technology to determine whether thedamage to tubing and casing. High permeability reservoir development process inthe middle, often working on the oil wells, operation process will involve the lowerpipe column, column depth if not accurate, will happen card layer phenomena, andthe magnetic positioning engineering logging can judge whether downhole tool to aspecified location, can guide the construction team to adjust tube column position.And with the development of oilfield, perforation, fracturing measures havebecome important measures to improve oil recovery. And the logging data to howspecific effects for the geological department evaluation of oil wells up after thehole, hole filling effect measures can provide reliable basis for long.④in latedevelopment stage of oilfield, thin and poor reservoirs become main researchobject to improve the recovery ratio, at present due to the instrument itself defectsand the well condition reason, conventional impedance type annular waterdetector can not satisfy the measurement of low fluid layer, and the ball collectingimpedance instrument can provide the output of each layer for low-yield wells, toprovide detailed data for geological development staff. The high permeabilityreservoir has high water cut, high residual oil phenomenon, interlayer contradiction,using isotope five logging parameters can understand the contradiction betweenlayers. In short, if meet the maximum extent in high permeability reservoirdevelopment needs, how to better for oilfield development provides the loggingservice, how to cope with the geological departments of logging of oil field, is theconstant pursuit of testing technical staff target...
