At present, Most oil field' exploitation of our country have went into middle and later periods, actual conditions of oil reservoir have reflected that the geological materials in the past can't already be more detailed, so the one that is being developed the fine distribution of describing and studying the surplus oil of oil reservoir is paid attention to. This paper as research object , utilize many kinds of means carry on this oil reservoir describe with surplus oil distributing with Zhongyuan Oil Field Wen 15 broke piece law synthetically study.Production indicate that Wen15 is already at high containing moisture stage, adjust well, upgrade from nearest one well is it think to come, still have certain potentiality, mend and make " difference storey " of some wells to produce oil. Phenomenon these prove this piece for greater potentiality on one hand, on the other hand prove geological characteristic in this piece not enough understand, one layer of departments of original development still has some questions to make up. So launch the oil reservoir and describe meticulously, set up the accurate geological model, strengthen dynamic analysis, carry on the numerical simulation of oil reservoir, study the surplus oil, propose the comprehensive administration scheme, achieve the goal of giving stable high yields irrespective of drought or water logging in the oil field finally. Because Shasanshang reservoir is the main oil reservoir, fine describe also with Shasanshang oil reservoir as the main fact oil reservoir have. Calculating and distributing the law to study with the surplus oil for the meticulous research of the structure, reserves especially in research.To in the above contradiction, according to the rock characteristic and rock physical parameter, compare meticulously with the foundation and divide the unit of flowing with the stratum. Adopt the " fastenning the contrast of answering, control in grades " method at first, carry on the rough contrast among the wells, look for and control layer steadily. Some sand group store the whole marker bed that district distribute steadily in, that can regard as the flow first class control sign of unit to divide. Is it fetch every analysis, sampling well test materials is it log well curve to combine to utilize secondly, confirm and flow the quantity of division and sign of the unit. Third, regard fetching the heart well as the centre, choose the skeleton section, and confirm it marks the distribution state in the whole district that the unit of flowing is divided. Fourth, radiate with skeleton section to around well , carry on the whole district flow Entrance is divided and the the whole district close. The fifth set up the unit of each flowing and divide one layer of databases. Through subdividing the unit of flowing, meticulous research does not store layer the quality and influence developed to water flooding, combine numerical simulation technology, seek the distribution of the surplus oil more accurately.According to fine oil reservoir describe and various kinds of oil reservoir geological model parameter offered that rebuild, again with leave unit of calculating on unit, estimate Wen15 geological reserves, flow Entrance in the level and vertical distribution characteristic that have each to understand, offer the reliable geological basis for tapping the latent power in further adjustment of the oil field.Regarding deepenning geology of oil reservoir to know and describe with the oil reservoir meticulously as the foundation. Adjust with oil reservoir well water logging layer explain and oil well produce liquid section, note well absorb water, adopting and synthesizing with ration -half ration, adopt the numerical simulation law of oil reservoir and use every static behavior of oil reservoir and produce the dynamic materials in an all-round way, after fitting in history, get underground surplus oil in the oil reservoir more accurate quantitative description.On the basis of the thing that describe and deepen study the surplus oil, make sure practice -know-course that practise again, dispose, implement in turn wholly, surplus oil taping the...
