摘要
赛东洼槽低孔隙度、低渗透性储集层发育,压裂改造是提高单井产能的主要技术手段,压裂选层成为重要课题。根据录井对该区30口探井精细地层对比,对阿尔善组、腾一段、腾二段储集层的岩性、物性、含油性等特征进行分析,并根据试油、试采资料,研究油气产能与储集层特征的关系,最终建立了该地区碎屑岩储集层压裂录井参数标准。在赛东洼槽S 108井、S 80井腾二段碎屑岩压裂井的试验表明,其应用效果较好,有望在二连探区各富油凹陷主力储集层段进行推广。
Low porosity and low permeability reservoirs in Saidong trough are well developed.Fracturing treatment is the main technical means to improve the productivity of single well.Fracturing horizon optimization has become an important topic.Fine stratigraphic correlation of 30 exploration wells in this area was made based on mud logging,the characteristics of reservoir lithology,physical property and oil-bearing capability in A′ershan formation,the first member and the second member of Tengge′er formation were analyzed.According to the data of potential test and production test,the relationship between oil gas production capacity and reservoir characteristics was studied.Finally,the standards of mud logging parameters for fracturing clastic rock reservoir in this area were established.The test results for fracturing the clastic rock reservoirs in the second member of Tengge′er formation of wells S 108 and S 80 in Saidong trough show that the application effect is good,and it is expected to be popularized in the major reservoirs of oil-rich sags in Erlian exploration area.
