【摘要】：遼河坳陷結(jié)晶基底油氣資源豐富,在遼河的三大凹陷基底潛山以及中央凸起均發(fā)現(xiàn)規(guī)模油氣藏。本文通過(guò)系統(tǒng)分析巖芯、巖屑和旋轉(zhuǎn)井壁取芯熒光、鑄體和傳統(tǒng)巖石薄片,對(duì)遼河坳陷太古宙基巖及其中的侵入體的巖石類型、含油性、儲(chǔ)層成因及影響因素等進(jìn)行了綜合研究。結(jié)果表明,遼河坳陷結(jié)晶基底巖石包括2大類、14個(gè)亞類、30多種巖石類型;巖石的含油性與巖石類型、構(gòu)造作用和古風(fēng)化溶蝕淋濾作用的改造密切相關(guān)。在對(duì)不同巖性巖石的物理特征與測(cè)井曲線特征大量對(duì)比分析和研究基礎(chǔ)上,建立了巖性與測(cè)井曲線的對(duì)應(yīng)關(guān)系,實(shí)現(xiàn)了基巖巖性的測(cè)井識(shí)別,為勘探部署、儲(chǔ)量計(jì)算等奠定了基礎(chǔ),也為類似基巖油氣藏的勘探研究提供重要借鑒。
[Abstract]:The crystalline basement of Liaohe depression is rich in oil and gas resources, and scale reservoirs are found in the basement buried-hill and central uplift of Liaohe depression. The rock types, oil content, reservoir genesis and influencing factors of Archean bedrock and its intrusions in Liaohe depression are studied. The results show that the crystalline basement rocks in Liaohe depression include 2 types and 14 subclasses of more than 30 kinds of rocks. The petroliferous properties of rocks are closely related to the transformation of rock types, tectonics and paleo-weathering dissolution and leaching. On the basis of a great deal of comparative analysis and research on the physical and logging characteristics of different lithologic rocks, The relationship between lithology and logging curve is established, the logging recognition of bedrock lithology is realized, which lays the foundation for exploration deployment and reserves calculation, and also provides important reference for exploration research of similar bedrock reservoirs.
