摘要

马厂地区渐新统沙河街组沙三(3)亚段为大型推进式三角洲沉积。在埋藏成岩过程中经历了以组份溶蚀作用和溶蚀-沉淀作用为主的成岩变化。一次溶蚀作用产生于生油高峰期前

形成的溶孔是油气聚集的有效储集空间;二次溶蚀作用发生于生油高峰期后

热裂解气形成之前

对深部和超深部天然气的聚集具有重要意义。

Abstract

The Oligocene Sha-3 (3) submember in Machang region

Dongpu Depression is a large progressive deltaic deposit.It mainly underwent component-dissolution and dissolved-precipitation during the process of burial diagenesis.The first dissolution oc-curred prior to the peak period of hydrocarbon generation

and the dissolved pores areavailable spaces for hydrocarbon accumulation;the second dissolution happened after thepeak period and prior to the formation of cracking gas

the pores formed may have consid-erable significance for gas accumulation in deep and superdeep strata.
