Effect of slope break belt on facies and reservoirs in Erlian Basin
Online published: 2010-12-15
Various slope break belts are widely developed in Erlian rifted basin. According to the genesis, they can be divided into four types, including faulted, flexural, erosional and depositional slope break. They can also be classified into antecedent, syngenetic and epigenetic slope break according to their formation time. Among them, antecedent and syngenetic slope breaks have control effect on layers, facies and sandstones. Different types of slope breaks form various styles of slope break belts laterally and experience transformation vertically. And consequently, different types of hydrocarbon reservoirs are spatially distributed in a complex pattern. Slope break belt is one key factor for the formation of hydrocarbon reservoirs. Therefore, different slope break belts should be especially distinguished. In addition, it is necessary to analyze their control effect on layers, facies, sandstones and reservoirs, so as to provide instruction for hydrocarbon exploration.
