摘要
通过文献调研,国内外学者在深层-超深层碎屑岩储层方面研究较少。为了研究深层-超深层碎屑岩储层的发育机制,基于国内外学者的研究成果,将影响深层-超深层碎屑岩储层及其物性的因素总结为沉积作用、成岩作用(压实作用、溶解作用、胶结作用)以及其他作用(异常高压、膏盐和泥质盖层、热循环对流、早期油气充注、埋藏方式、砂泥岩互层状况、构造裂缝、古地温梯度等)。
Scholars at home and abroad have done little research on deep-ultra-deep clastic reservoirs. In order to study the development mechanism of high quality reservoir, the research results of domestic geologists at home and abroad are synthesized in this paper. The factors affecting deep-ultra-deep clastic reservoirs and their physical properties are summarized as sedimentation, diagenesis(compaction,dissolution, cementation) and other processes( abnormal high pressure, gypsum salt and argillaceous caprock, thermal circulation convection, Early oil and gas filling, burial mode, sand-mudstone interbed condition, structural fracture, paleo-geothermal gradient, etc.).
