一、方法的研究在油气勘探中,常常遇到一些非构造运动作用成因的压实构造,如沉积时受古地形起伏不平和砂泥沉积不均等因素的影响,在向成岩方面转化的过程中引起的差异压实作用所形成的构造。这些构造对油气的分布、储量有一定的影响。由于差异压实作用在沉 I. Methodology In the exploration of oil and gas, some non-tectono-tectonic compaction structures are often encountered. For example, due to the fluctuation of palaeo-topography and uneven deposition of sand and mud during deposition, during the process of conversion to diagenesis Differences caused by the compaction effect of the formation of the structure. These structures have a certain impact on the distribution and reserves of oil and gas. Due to the difference in the role of compaction Shen
