Changbei gas field is a river lothology-stratigraphic trap gas pool on the west trend monocline background, it is located in the east of the basin, it has thin bed, low-porosity, low-permeability, low-pressure, low-deliverability character and develop difficulty(HeGuang-huai, 2002), especially to develop this thin bed and unhomogeneity seriously river sandbody gas pool is much difficulty.

长北气田位于盆地东部，属于西倾单斜构造背景上的河道岩性-地层圈闭气藏，具有薄层、低孔、低渗、低压、低产和非均质性强等特点，开发难度大，尤其是利用水平井开发如此薄层的非均质性严重的河道砂岩气藏难度更大。

But the geological and geochemical analyses showed that there existed a set of high quality marine source rock in the platform slope facies of Middle Ordovician Pingliang Formation. The oil and gas generated from the source rock of Pingliang Formation was accumulated firstly in the central Palaeo-uplift and its surrounding regions. The thermogenic asphalt in palaeo-uplift carbonate reservoir indicated that oil accumulation completed transition from oil to gas in the Lower Crataceous. Along with the palaeo-uplift axis convection and the formation of westward monocline in the Late Crataceous, gas from the palaeo-reservoir was finally accumulated in the weathering crust of Majiagou carbonate reservoir.

地质和地球化学分析证实，盆地西、南缘台缘深水斜坡相的中奥陶统平凉组存在优质海相烃源岩，其形成的油气最早富集在中央古隆起及其周围；伴随着中央古隆起带轴部的向东迁移和早白垩世末盆地西倾大单斜的定型，平凉组烃源岩在早白垩世生烃高峰期生成的天然气和早期古油藏裂解气，由中央古隆起带向北东方向发生二次运聚，最终在盆地中部奥陶系马家沟组风化壳中聚集成藏，即形成靖边大气田。

The aforementioned gas mixture comprises natural gas and/or naphtha or refinery gas or two or more of said gases.

The conventional development fashions for the gas condensate fields mainly are natural depletion and cyclic gas injection: using the method of gas injection require know clearly about the formation and need more investment, so this method is used few in our country; although a good deal of condensate oil is loss in the formation because of the appearance of retrograde condensation by the method of natural depletion, it is the main development method in China because of the lower investment and lower perception level abut the formation .

凝析气藏主要有衰竭或循环注气两种开发方式：注气开发对地质条件以及资金投入要求较高在我国仅有少数气田采用该方式：虽然采用衰竭开发方式大量的液态烃由于反凝析而损失在地层中，但是由于其低的投资费用、对地质认识程度要求不高，该方式在我国仍然是主要开发方式。

Ii. Tap water, heating, air conditioning, hot water, coal gas, lipuefied petroleum gas, naturalgas, methane gas, coal/charcoal products for household use
