摘要
通过精细对比和解剖苏里格气田苏20区块气层分布,总结苏20区块气层研究区的分布特征,发现苏20区块横向上气层分布具有多层叠置的特点,石盒子组及山西组各个层段均解释有气层或含气层,气层纵向上主要集中分布在盒8段和山1段。综合沉积相、砂体展布及储层发育特征,认为该区以盒8下亚段为主要储集层位,其他层位作为补充,具有一定的开发潜力。同时对气井依据储能系数,将气层划分为3类,储能系数大于0.5为Ⅰ类气层,储能系数0.3～0.5为Ⅱ类气层,储能系数0.1～0.3为Ⅲ类气层。
Through detailed comparison and anatomizing the distribution of gas-bearing formation of Block Su-20 in Sulige Gas Field,the vertical and horizontal distribution features were summed up,it was found that the horizontal distribution of gas reservoir of Blocks Su-20 was the characteristics of multi-layer overlay,Shanxi(S) Formation and Shihezi(H) Formation were the interpretation of the various layers or gas-bearing reservoirs,the gas reservoirs were mainly distributed vertically in H8 and S1.It is considered that the sedimentary facies and sand body characteristics of fabric and reservoir development are synthetically analyzed.It is found that the area in H8X is the main layer,the other reservoirs as a supplement have a certain potential for development.On the same time,based on gas storage coefficient,the gas reservoir is divided into three categories.Energy storage coefficient greater than 0.5 is type Ⅰ gas,energy storage coefficient of 0.3 ~ 0.5 is the type Ⅱ gas,energy storage coefficient of 0.1 ~ 0.3 is type Ⅲ gas reservoir.
