【摘要】：该研究项目结合最新的层序地层学理论和计算机等信息化手段,综合应用沉积学、地球物理等多学科最新成果,借鉴、汇总前期研究的基础上,综合利用地震反演、岩性测井、岩屑录井、岩心观察、古生物化石等资料,对松辽盆地北部嫩江组地层进行系统研究,实现地质分层与地震分层的有机结合。共完成了10个地震剖面的T1层、T07层、T06层、T03层4个主要地层界面细分,重点建立了长垣及其以西地区嫩江组黑帝庙油层划分对比标准方案,系统总结了长垣及其以西地区嫩江组各段划分特征标志、黑帝庙油层砂组发育特征及其分布规律,编制了嫩江组黑帝庙油层连井地层对比剖面图,丰富了长垣及以西地区嫩江组的地层学成果,为大庆探区嫩江组地质时代的标定和黑帝庙油层的勘探提供了科学的依据。项目的重要成果和认识,主要表现为以下四点:1)完成了5个三维地震工区174余口探井声波时差数据核查,开展25口重点井解剖、121口井单井合成记录,完成10条地震剖面T03、T04、T05、T06、T07和T1层解释,开展10条连井地层对比剖面图,分析录井图211份、标准测井曲线292份,丰富了区域资料储集;2)在LandMark的Openworks系统的运算下,通过Strataworks与Seisworks联动分析,应用井震结合统一解释,取得了较好的效果;3)对长垣及以西地区的嫩江组地层研究成果进行梳理,系统总结了6个地层界面的地质特征;4)通过地震剖面再解释,总结了T06、T05、T04及黑帝庙油层划分对比方案。
[Abstract]:This research project combines the latest sequence stratigraphy theory and computer and other information means, comprehensively applies the latest achievements of sedimentology, geophysics and other disciplines, draws lessons from and summarizes the previous research, and makes comprehensive use of seismic inversion, lithologic logging, cuttings logging, core observation, paleontological fossils and other data to systematically study the strata of Nenjiang formation in the north of Songliao Basin, so as to realize the organic combination of geological stratification and seismic stratification. A total of 10 seismic profiles have been subdivided into four main strata: T1 layer, T07 layer, T06 layer and T03 layer. The standard scheme for dividing and comparing Hedimiao reservoir of Nenjiang formation in Changyuan and its west area has been established, the characteristic marks of each section of Nenjiang formation in Changyuan and its west area, the development characteristics and distribution law of sand formation in Hedimiao reservoir of Nenjiang formation have been systematically summarized, and the strata correlation profile of Hedimiao reservoir in Nenjiang formation has been compiled. It enriches the stratigraphy results of Nenjiang formation in Changyuan and its west area, and provides a scientific basis for the calibration of geological age of Nenjiang formation and the exploration of Hedimiao oil layer in Daqing exploration area. The important achievements and understandings of the project are as follows: 1) the acoustic time difference data of more than 174 exploration wells in 5 3D seismic areas have been verified, 25 key wells have been dissected, 121 wells have been synthesized, 10 seismic profiles T03, T04, T05, T06, T07 and T1 have been interpreted, 10 connected formation correlation profiles have been carried out, 211 logging maps and 292 standard logging curves have been analyzed, which enriches the regional data reservoir; 2) under the operation of Openworks system of LandMark, through the linkage analysis of Strataworks and Seisworks, good results have been obtained by combining well earthquake with unified interpretation; 3) the research results of Nenjiang formation strata in Changyuan and west areas are combed, and the geological characteristics of six strata interfaces are systematically summarized; 4) through seismic profile reinterpretation, the division and correlation schemes of T06, T05, T04 and Hedimiao reservoirs are summarized.
