为明确麦捷让构造卡洛夫-牛津阶气藏的控藏因素、掌握油气富集规律,利用层拉平技术研究了麦捷让构造的形成与演化,明确了麦捷让古构造和现今构造的形成时期以及规模;通过研究油气的生成、运移与构造形成之间的时空匹配关系,解决了卡洛夫-牛津阶气藏控藏因素不清的问题。研究得出,现今构造对麦捷让气藏的形成影响小,古构造是影响气藏形成的主控因素,古构造的大小决定了气藏的储量规模和油气分布规律。通过控藏因素的研究,不仅明确了气藏类型,也探索和掌握了气田的高产富集规律,即在古构造高点或古构造的上斜坡,储层物性好、气井产量大,远离古构造高点或位于下斜坡,则储层物性差、气井产量低。
In order to clarify the controlling factors for the construction of the Karlov-Oxford gas reservoirs by McGrath and to master the laws of oil and gas enrichment, the formation and evolution of the structures of Magneto were studied by using the layer leveling technique. The formation period and the scale of the reservoirs; and solved the problem of unclear reservoir holding factors in the Kalov-Oxford reservoirs by studying the space-time matching relationship between the formation, migration and tectonic formation of oil and gas. The study shows that the present structure has little influence on the formation of gas reservoirs by Mai Jie, and the palaeostructure is the main factor that affects the formation of gas reservoirs. The size of the paleostructures determines the reserves scale and the distribution rules of oil and gas reservoirs. Through the study of reservoir holding factors, not only the types of gas reservoirs but also the laws of high-yield and enrichment of gas fields are explored and mastered. That is, at paleocontinental or paleo-structural upper slopes, reservoir properties are good, gas well production is large, Tectonic high or located in the lower slope, the reservoir physical properties, low gas wells.
