Optimization of horizontal well pattern in low permeability layered reservoir

The southern part of Jin45 fault block is a low permeability layered reservoir with thin oil layer thickness. And the development horizontal well pattern has good economic benefit in block. distribution quite different. main stable, but non-main unstable. In this study, through engineering method and numerical simulation method, direction, form, spacing length are optimized to determine layer. On basis, according principle "parallel deployment wells sharing injection-production pattern", preliminarily designed ensure effect greatest extent.
