| 摘 要： | 马五13是靖边气田统5井区的主力产气层,其岩性主要为潮上带及潮间带含膏(结核和晶体)泥-粉晶白云岩.马五13经历了准同生白云石化、准同生石膏生长和交代作用、重结晶作用、表生岩溶作用、埋藏白云石化作用、埋藏溶解作用、矿物充填作用和去白云石作用等8种主要成岩作用,其中对马五13白云岩储层演化影响较大的是表生岩溶作用、埋藏溶解作用和各种矿物对孔洞缝的充填作用.在对成岩作用研究的基础上,把马五13划分为4个成岩作用区.Ⅰ、Ⅱ区是储层发育有利区,Ⅲ区有少量储层发育,Ⅳ区储层不发育. |
| 关 键 词： | 统5井区 马五13 成岩作用 储层发育有利区 |

| Abstract: | M513 is mainly gas productive reservoir,which lies in the Well Block Tong5 of the Jingbian gas field.The lithology is chiefly gypseous(crystal and tubercle)micritic-powdered dolomite rock which is supralittoral or intertidal.M513 udergoes 8 kinds of diagenesises,which is penecontemporaneous dolomitization,penecontemporaneous gypseous growth and metasomasis,rejuvenation of crystals,epigenetic rock's dissolution,burial dolomitization,burial dissolution,mineral packing action and dedolomitisation.But epigenetic rock's dissolution,burial dolomitization and mineral packing action mainly influence on reservoir evolution.M513 is divided into 4 diagenesis blocks in Well Block Tong5. |
| Keywords: | Well Block Tong5 M513 submember diagenesis reservoir range of profitability |
