【摘要】：川中磨溪—高石梯地區(qū)龍王廟組可劃分為兩個三級層序。通過大量巖心、薄片以及測井資料綜合分析,磨溪—高石梯地區(qū)龍王廟期整體屬于局限臺地沉積,可劃分為臺內(nèi)灘、灘間洼地以及o_湖亞相。以臺內(nèi)灘顆粒含量、沉積構(gòu)造以及單層灘體沉積厚度為基礎(chǔ),結(jié)合測井響應(yīng)特征分析,將臺內(nèi)灘劃分為灘核、灘翼以及白云巖坪等微相,并建立了臺內(nèi)灘的3種典型沉積序列:灘翼—灘核—白云巖坪、o_湖—灘間洼地—臺內(nèi)灘,以及灘間洼地—臺內(nèi)灘。層序格架內(nèi)臺內(nèi)灘的縱橫向發(fā)育特征表明:SQ_2時期較SQ_1時期更為發(fā)育,灘體單層厚度和總厚度均較大,層序界面附近的灘核—白云巖坪沉積序列上部為最有利的儲層發(fā)育相帶。
[Abstract]:In Moxi Gaoshiti area and Longwangmiao formation can be divided into two three order sequences. Through a large number of core, thin section and well logging analysis, grinding Longwangmiao period - Xi Gaoshiti area belongs to the whole local platform sediment can be divided into interplatform beach, the beach between the lowland and o_ Lake subfacies. On the beach in particle content, sedimentary structure and sedimentary thickness of single-layer flat body, combined with the characteristics of logging response analysis, taiwan beach beach beach is divided into nuclear, wing and dolomite flat microfacies, and set up 3 kinds of typical sedimentary sequence of interplatform Beach: Beach wing beach nuclear Baiyun Yan Ping o_, Lake Beach - intraplatform depressions, and the beach - intraplatform depressions. The sequence framework intraplatform vertical development characteristics show that SQ_2 is more than SQ_1 during the period of development, the beach body monolayer thickness and total thickness are large, sequence near the interface core dolomite flat beach sedimentary sequence The Department is the most favorable reservoir development phase.
