苏里格东部马5五储层特征及成藏控制因素
Reservoir Characteristics and Controlling Factors of M55 Sub-member of Majiagou Formation in the East of Sulige Area
摘要
Abstract
As the new member of oil-gas exploration,breakthrough in oil-gas exploration has been made in resent years at M55 Sub-member of Majiagou Formation in Ordovician. On the basis of the survey of core of well drilling,analysis of well logging, identification of lamela,analysis of physical characteristics,the article studied the reservoir characteristics and analyzed the controlling factors of reservoir in M55 Sub-member of Majiagou Formation in the east of Sulige Area. It suggested that the main reservoir is a dolomite gas pool in M55 Sub-member in the east of Sulige Area and there is fine corresponding relationship between the gas pool and dolomite. The intercrystalline pore is the main type of reservoir space. Among all kinds of rocks,the medium crystalline dolomite,fine crystalline dolomite and powder crystalline dolomite have the best physical characteristics of reservoir. The sedimentary microfacies mainly provided the material basis for the development of reservoir and the dolomite controlled the distribution of effective reservoir. Besides,the diagenesis of buried period in the middle and later period is the most beneficial to the reservoir development. Meanwhile,nose structure has certain influence on the gas pool,while paleokarst takes little effect on reservoir in M55 Sub-member.关键词
