Study On Characteristics And Adjustment Countermeasures Of Conglomerate Reservoir In Area 530 Of Karamay Oilfield

We conducted in-depth study of the conglomerate reservoir geological features in the 530 well lower wuerhe reservoir of district no.8 in kelamayi oilfield base on core datum, thin section and analysis assay datas. Besides, on the basis of above, combining production ynamic information on oil layer producing degree, recovery capacity, pressure characteristic, water cut trends, decline law and water breakthrough characteristics a systematic analyze and evaluate, and combined with the actual production characteristics of the reservoir, the reservoir further effective development of countermeasures were developed, the research of development adjustment principles, adjust the timing, series of strata adjustment, injection-production well adjust, well patterns and spacing adjustment are studied, too.Through the research results, it shows that the 530 well lower wuerhe reservoir of district no.8 in kelamayi oilfield depositional environment is mainly piedmont diluvial, the reservoir rocks are mainly fine-grained small conglomerate, ranging from fine-grain conglomerates with thin conglomeratic sandstone combination of thick massive deposits, poor roundness and poor sorting, composition and structure of the low maturity, lowporosity and permeability resevoir. In the longitudinal direction, resevoir are mainly distributed in P2W2, followed by the upper P2W3 and lower P2W1.Among them, the P2W2-2 have the best reservoir properties. In study area, the reservoir is controlled by both tectonic and depositional. The major structural impact maily reflected on that the distribution of northern resevoir is controlled by faults of 415 wells and 85,407 oil wells, and the oil-water boundaries and reservoir distribution of eastern reservoir are controlled by the eastward tilt strata. The reservoir is divided into three blocks of Ⅰ, Ⅱ, Ⅲ. The Ⅰ area wells have high oil production, the Ⅱ area wells are generally low-yielding but stable, and the Ⅲ area basically has lost production capacity due to the influence of formation water and serious water channeling.Some feasible countermeasures have developed to make the reservoir development adjustments base on the 530 well lower wuerhe conglomerate reservoir of district no.8 in kelamayi oilfield features analysis and research.
