Research On Distribution Rule Of Thin Intercalation Inside Thick Oil Reservoir In Lamadian Oilfield

With sedimentary characteristic of sandbody and need of exploitation in ultra-high water stage inside thick oil reservoir and analysis principle of administrative levels, this paper gave the sedimentary model regulation about Lamadian Oilfield. on the analogy of outcrop by same sedimentary model in field from cause of formation, according to true core well data , modern fluvial sedimentary with large dynamic and static data, distinguished thin intercalation from sandbody of thick oil reservoir. Based on this ,the study system about distribution characteristic of thin intercalation inside thick oil-reservoir are brought forward. In addition ,Integrated feasibility of this means In theory and put forward identifying ways of thin intercalation inside thick oil-reservoir, established 4 types(straight line, curve, tree branch and latent spices and so on) 7 kinds of Space combination type and the corresponding type of remaining oil. By distribution characteristic of thin intercalation, and summed-up an impact of different types thin intercalation upon effect of gas-oil pervasion and corresponding method of tapping remaining oil. A set of method form gradually keeping with thick oil reservoir in ultra-high water stage and obtain enormous economic performance through several hard years. Research on reservoir Building construction is foundation of analyzing thin intercalation inside thick oil-reservoir sandbody which is gradually convinced. Factors of influencing remaining oil distribution are so many that we should take corresponding measure according to the main; is a course of point(well point)–line(section)—face(sedimentary faces belt)--body(sandbody) and is also a opposite and gradual acquaintance with sandbody. following oilfield exploitation going deep into and technique means of oil reservoir description advancement continuously ,acquaintance with sandbody will be close to impersonal status .
