鄂尔多斯盆地安塞油田长10油层组富油因素分析
Research on the rule of reservoir enrichment of Chang10 Formation in Ansai oilfield of Ordos Basin
摘要
Abstract
Based on the fundamental geological elements of the reservoir forming, some influences and controlment effects on the reservoir forming were analyzed, such as the source rocks,sedimentary systems, association of reservoir rock and rap rock, reservoir perfect area,paleostructure and paleotopography of lake basin. The effective source rock of Chang7 and Chang9 Formation controlled by the distribution of deep lake provided oil sources for Chang10 Formation of Ansai oilfield. Distributary channel sandbodies delta plain was the main places for reservoir forming. What's more, secondary porosity formed by diagenesis improved properties of reservoirs, good association of reservoir rock and rap was also formed in the delta -lake sedimentary system. Corresponding sequence stratum and development of sand was controlled by paleostructure and paleotopography of lake basin.关键词
