贝尔凹陷基岩潜山油成藏主控因素及模式
MAIN CONTROLLING FACTORS AND MODEL OF THE BURIED OIL RESERVOIR FORMATION IN THE BASEMENT ROCK OF BEIER SAG
摘要
Abstract
Obtained from both the anatomies of the oil reservoir or oil accurence wells and the studies of the space matching relation between the reservoirs/well and the formating conditions of oil reservoirs, the type of the buried hill oil reservoirs in basement rock if Beier Sag is considered to be faulted buried-hill oil reservoir. The reservoirs are mainly distributed at the rises of both between the delves and in the lows. The reservoir formation and distribution are principally controlled by the following 4 parameters; the source rock in Nan No. 1 Member controls the oil reserovir formation and reservoirs' distribution; the above two rises are the favorable positions of oil accumulation and distribution; the dissolved pores and caves provide the accumulation space for the reservoirs; the extended faults in the early stage not only present the barrier conditons and structural background of the oil enrichment, but connect laterally with the source rock in Nan No. 1 Member. The oil reservoir forming model in the basement rock is that under the action of buoyancy, the oil generated in the resource rock laterally migrates through the unconformity surface and then connects with the high faulted & buried hill trap at the rises between the delves and in the lows and finally forms oil reservoirs.关键词
