Low Permeability Reservoir Production Relation Theory Research And Application

Test oil production is a trial of a quite oil material important parameters, it is theimportant basis for formulating development plan, also is the important developmentDingChan reference. Because the geological engineering, the differences between the two, tryoil production and development by production have very big difference.So we know lowpermeability reservoir test oil production and development of the difference of the earlyproduction flexibility and the reasons, and study the relationship between them which canprovides the basis for making the block development scheme.This article through the consult literature at home and abroad and according to thepractical geological conditions of daqing oil field, this paper expounds the concept of lowpermeability oil field boundaries and classification, the low permeable oilfield is divided intothree kinds, namely common, especially low and ultra low permeable oil fields. in view of theperipheral oil fields of daqing oil production of the well test data and production material.lowpermeable oilfield production equation is based on Darcy law and J.D upuit formula. Weanalyze the factors which include supply radius, the reservoir permeability, homogeneous andsedimentary microfacies, According to the oil Wells tower of oil parameter analysis andproductivity prediction practical application, result and the actual conform,and studying onthe unstable IPR theory of previous research and production material of statistical analysis,we get the relationship betweenputaohua reservoir and low permeability reservoir Fu Yangtest oil production and output production, and form two fixed production methodsthe, bystudying on the relationship between try oil production and the production output whichdirect production exploratory Wells effectively and ensure the production process in hasexploratory Wells stable production material, the change law of pressure data and submitblock reserves required parameters. Combining theory with practice, use oil production indexmethod to establish relation putaohua reservoir and low permeability reservoir Fu Yang try oilproduction and development of the relationship between the initial production, give formulasuitable conditions, using the yield, try oil stage production of the differential pressure andeffective thickness can compute the oil than try oil production index, the use ofdevelopment block to the average effective thickness to calculate the different productionpressure difference of stable yield under development, and through the actual productionverification, and sounding try oil production according to establishing a reasonable blockdevelopment plan and guide the new block development.
