摘要
浅层气指埋深小于1500m的各类天然气资源,主要包括生物气、油型气、煤成气、水溶气等。我国的浅层天然气资源主要分布在南方沿海小型中新生代盆地,东、西部含油气盆地及主要含煤盆地。气藏类型分为3种:原生超浅层微气藏、近源浅层小气藏和浅埋常规气藏。其开发特点是:压力低、产量小、开采工艺简单、投资规模小。
Abstract
Shallow gas is specialized to various natural gas resources buried shallower than 1 500 m, including biogas, oil gas, coal-formed gas, water soluble gas and etc..China's natural gas resources are primarily distributed in south China coastal regions, small Meso-Cenozoic basins, hydrocarbon-bearing basins in East and West China and major coal basins.Gas pools could be divided into three kinds: 1.super-shallow primary micro-pools; 2.proximal shallow small pools; 3.shallow conventional pools.The exploration of shallow gas is characterized by lower pressure, small production, simple technique and less investment.
