According to those analysis and the background of geological evolution of basin, the kind of hydrodynamics was regarded as compaction before y3 and then as compaction - osmosis after y3. futhermore, the key time of oil and gas reservoir formation was summarized, it is furthermore, the main cause of high pressure formation was believed that the compaction was not enough in paleogeothermal gradient, meanwhile, analyzing the cause of the low pressure nowadays, it was the uplift and erosion of stratum or pressure divulgence because of seal and so on
另外，還確定油氣成藏的關鍵時期為伊敏組沉積末。再者，認為欠壓實是最大埋深狀態下，超壓形成的主要原因，同時分析了形成現今負（低）壓的原因，其原因為地層抬升剝蝕、壓力因封閉層的泄漏等。最後，恢復出各主要目的層的古流體勢的演化歷史，從伊敏組末至現今，油勢分佈特徵具有較好的繼承性。 -
The effect of overburden separation dynamic development under key stratum on grouting for bed separation space was analyzed, in order to deal with the problem that the current bed separation growing technology can not prevent the key stratum from breakage, put forward the isolated section - grouting technology for overburden bed separation space, integrated the virtue of growing for bed separation space and partial extraction, the bed separation grouting bodies, key stratum and isolated section pillars were made to constitute the load - carrying body all together, and to reach the purpose of reducing subsidence effectively, increase the coal seam extraction ratio, and accelerate the development of isolated section - growing technology for overburden bed separation space
摘要分析了關鍵層下離層動態發育對離層充填的影響，針對目前離層區充填工藝不能阻止覆巖關鍵層初次破斷的問題，提出了「覆巖離層分區隔離注漿充填」技術，它綜合離層充填與條帶開采技術的優點，通過離層區充填置換或減小分區隔離煤柱寬度，使「離層區充填體關鍵層分區隔離煤柱」形成共同承載體，從而達到有效減緩地面沉降的目的，提高了煤層采出率，促進了覆巖離層充填減沉技術的發展。 -
