Study On Sequence Stratigraphy In Moliqing Oilfield

In this paper, jilin oilfield reservoir in green area as the research object, guided by the principle of sequence stratigraphy, combining with the actual geological data in the study area, take well by single well analysis to union analysis method; On key strata in the study area, according to the seismic data of the profile features, logging and logging data, core description, the Murray analyzing green regional stratigraphic sequence and division; This paper for the first time in well combination of earthquake, mainly adopts rock log facies analysis in time frequency analysis technology division depositional cycle period time, the application layer principle of sequence stratigraphy, the contrast and division in the green area, established the sequence stratigraphic framework of green area. Constraints on the sequence stratigraphy framework system, deepening the hydrocarbon accumulation and the sequence of the corresponding relationship between understanding, analysis of oil and gas distribution, found out the oil reservoir in high water system tract, the water into the system domain, and the distribution of the lowstand system tract. Again on the basis of the sedimentary system and reservoir characteristics of this area in the research and evaluation, and combining the relevant geological and geophysical software was applied to the comprehensive analysis, using the log constrained inversion wave group technology for sand body distribution prediction of favorable area, analyzing the distribution of favorable sand body plane trend; And use a variety of hydrocarbon detection technology to find "dessert"; Corresponding achievements of geological maps; To forecast favorable oil and gas blocks, and hope that this research results to the future development of this area have the effect of a topic.
