Fine Structure Interpretation Of Fuyu Reservoir In Gaotaizi Oilfield

Fuyu reservoir in Gaotaizi oilfield formed in the basin sedimentation period, give priority to with deltaic deposit. After the implementation of 3 d seismic, to make full use of new technology, better understanding and accurately depict fuyu reservoir accumulation characteristics in the district, to further excavate its potential, therefore, Fuyu reservoir in Gaotaizi oilfield of fine structure are studied.Based on the theory of high-resolution sequence stratigraphy, sedimentology, combined with the research area of well logging, seismic and logging data of Fuyu reservoir in Gaotaizi oilfield of stratigraphic sequence has carried on the comprehensive analysis, reservoir subdivision into two cycle for a long time, six medium-term cycle and 17 short cycle, high resolution sequence stratigraphy framework was established.Using 3 d seismic data in the study area, in combination with drilling, logging,cross-hole seismic data, using synthetic seismogram, 3 d seismic data visualization, trend of similarity analysis, spatial analysis, spatial validation- section identification, such as when slicing, longitudinal profile proportion amplifier, more attributes- method and trend surface analysis and a series of technical fuyu reservoir in the studied area fine horizon interpretation,fault interpretation and micro structure interpretation. fuyu oil layer in the study area as a whole tectonic framework for " high in the south and low in the north, high east and low west,the central uplift", Top surface integral for a long axis near north north east to anticline,Fracture in the area are developed very well, larger faults, mainly distributed in the anticline axis direction for north west, limbs fracture times, due to the faults cutting action, and complicate the anticline form, forming a series of small anticline, graben and horst, fault terrace structure. And there are three main evolution period.Combined with drilling analysis in the study area has faulted anticline reservoir, fault-lithological oil pool, reverse fault terrace structural reservoirs. Integrated structure research,Integrated regional geological conditions, trap, reservoir, sedimentary facies, reservoir forming condition and production situation of adjacent Wells to determine the two favorable targets.
