沙参2井喜获高产油气流,这一重大突破不仅开拓了人们在该盆地找油的新思路,而且促使人们对以往通过各种手段所得到的宝贵地质资料作出新的判断和认识。众所周知,重力勘探是廉价而有效的勘探手段,它能反映出地壳深部的物质成分、结构,结晶基底的内部成分、构造、表面起伏状况以及沉积岩内部的物质成分和构造。早在五十年代末 The success of Shashen 2 well in high-yielding oil and gas flows has not only opened up new ideas for people to look for oil in the basin, but has also led to new judgments and understandings of valuable geological data obtained through various means in the past. It is well-known that gravity exploration is a cheap and effective exploration method. It can reflect the composition and structure of the deep crust, the internal composition of the crystalline basement, the structure, the surface undulations, and the composition and structure of matter within the sedimentary rocks. As early as the late fifties
