摘要: 将断层封闭性分为侧向封闭性和垂向封闭性两部分,利用断层两盘砂泥对接概率模拟的方法研究断层的侧向封闭程度,利用断面压力计算法研究断层垂向封闭程度;将两个分析结果组合判断断层的综合封闭能力.该研究可将同一条断层在三维空间上各不同位置处的封闭能力较客观地反映出来,具半定量特点.汤原断陷的断层封闭性实际分析结果正确,证明该方法可信.

Abstract: Fault sealing is divided into two parts,lateral seal and vertical seal.Sandshale juxtaposition probability is simulated to study the laterally-sealed ability of faults,the pressure of fault surface is calculated to study the vertically-sealed ability of faults.The two analysis results are composed to study the synthetic sealing ability of the faults.The sealing ability of every different state of a fault in three-dimension space can be abjectively evaluated in semiquantitative way.The analysis results of the fault sealing in the north of Tangyuan fault depression are correct.So the method is proved to be trustworthy.
