The Study On The Single Well Productivity Evaluation Of S Wellblock Y10 Reservoir Of Ordos Basin

S wellblock Y10 reservoir of Ordos basin are typical of low permeability reservoir. At present, in the S wellblock development process, Petroleum Geology and development issues have become increasingly prominent, in order to reduce inefficient and dry wells, maximize the reduction of the risks, you need to optimize productivity evaluation of suitable technologies and methods, so as to quickly identify S wellblock of the size and distribution of oil and gas enrichment zone capacity and deployment guide S wellblock district development programmes.This papers to Ordos basin S wellblock extended Y10 reservoir for research object, based on research district geological, and rock heart, and measuring wells and production dynamic information, carried out has research district purposes layer of formation fine divided and compared, and sand top micro constructed features and sand body exhibition cloth law research, and storage layer non-are mass characters features research, and measuring wells information pretreatment, and "four characters " relationship and the measuring wells information II times explained research, and to stress features research, and oil water real characters lower research, and storage layer parameter distribution features research and capacity evaluation.Studies have shown that Y10 reservoir in the study area was divided into extension 101 and the extension 102 two small layers. Among them, the extended 101 for the main layer, as the object of this paper; construction is nearly North-South direction, there are two structural highs, axis to the East, about 3 km in length North-South width of 1.5 km, structural decreases from East to West. Sand body is since North East to southwest of article banded exhibition cloth, ductility compared good, plane shàng connected characters good; extended 101 rendering strong non-are mass characters, real characters poor; extended 101 reservoir pore degrees lower for 13.5%, reservoir resistance rate is greater than 42 Ω.m, AC is greater than 237 μs/m, containing oil saturated degrees is greater than 53.5%; research district of hole, and infiltration in plane exhibition cloth shàng has must of similar characters, containing oil saturated degrees and constructed has must of similar characters; To stress value is rendered as the depth increases progressively larger trends but as the depth increases, the increase in stress is also changing; capacity were used in the study area comprehensive index method and quantitative prediction method of multivariate linear regression analysis capacity, analysis and forecasting methods and results, a variety of evaluation methods have advantages and disadvantages, so in the end select. The research carried out and completed, can greatly promote oil and gas exploration and development in the study area, is of great theoretical and practical significance.
