Sazhong Zone Injection-production System And The Potential For Adjustment Method

Sazhong zone Gaotaizi oil layer deposition is relatively stable, and obviously cycles, the overall trend is gradually thickening from north to south, Fine lithology changes, the color changes from shallow depth. Vertical, can be divided into high-â… ,â…¡high, high III, IV four high oil group, 26 Sandstone Group, 92 sedimentary units.â… of which five Sandstone Group, 17 sedimentary units; Group II high nine Sandstone Group, 34 sedimentary units; Group III high six Sandstone Group, 23 sedimentary units; Group IV high six Sandstone Group, 18 sedimentary units. Sazhong zone Gaotaizi oil delta front facies distributary channel and the sand inside and outside the front sheet sands, Its sedimentary type of division, the Portuguese formation with Savimbi, under which a single delta cycles of sedimentary background, previously margin sandstone type to further delineate its delta type. At present, the Central West, Central East, an area constantly North West, North East a zone broken, Western and North Western on January 2nd row Gaotaizi oil layer of the low rate of decrease, the rate of decline of 10% in developing good effect. Well in the current network conditions under which West, Western, North January 2nd row Gaotaizi oil layer of the greatest ultimate recovery. Gaotaizi reservoir water flooding control generally higher, East Gaotaizi. South East Gaotaizi water flooding control of a higher degree Eastern and Western Gaotaizi Gaotaizi compared to other Gaotaizi water flooding control block less. From the point of view Layer, Layer subdivision mining areas of water flooding a higher degree of control over mining area of water flooding control level. Well from the Internet, constantly West 5:00 Act and using irregular 5:00 a law of South East Gaotaizi water flooding control of a higher degree.
