The Reseaching Of Applying The WELL ERT Technology At The Reservoir Of Low Porosity And Low Percolation Of Yanhewan Oil Region

Low porosity and low percolation of oil and gas resource are very important in the oil and gas resource of our country, and it must be more important and more larger proportion in the pace of the developing of exploring level in the future . At present, changqing oil field has been explored 61% of the low porosity and low percolation reservoir and the yield of this reservoir has occupeded 54.4% of the yield of whole year.So, low porosity and low percolation of reservoir must be the main battlefield of the oil exploring now even for more longer time , reseaching the low porosity and low percolation reservoir are very important to the developing smoothly of the oil industry of our country .The paper mainly begins with the geological background of yan25 well region of ordors basin, applying Geology, Well logging, DST, Test and production materials to establish reservoir parameter interpretation, oil and water identifying plots. Carry out re-processing of logging data, reseach of four poroerties relations ,reseach the geology base of well ERT(Electrical Resistance Tomography) and ERT inverse,tablished 3D geological model through the software of PETREL.Then take the resistance of region of ERT inverse and the technoloigy that is under the control of facies ,seting up the 3D geological model of resistance of reservoir ,GR,the degree of saturation of oil and oil's thickness . Through all of that predict the prospective area go step of further.
