The characteristics, reservoir quality and types of lacustrine braid deltas

A braid delta is an important type of lacustrine deltas. Unlike fan deltas and normal deltas, the braid deltas are widely developed and characterized by well-sorted sediments, minor amount of matrix, relatively good porosity and permeability. The sandstone bodies always occur as sheets over a wide range of scales, and thus have significant reservoir potential. The sedimentary characteristic, reservoir quality and types of the braid deltas are discussed in detail in the present paper.
