泥枪震源激发装备技术的初步研究

Research on the mud gun technology

随着石油勘探对环保要求的提高,在滩浅海过渡带及沼泽地区无法使用陆地可控震源和海洋气枪震源船,而当地政府和油公司也禁止使用炸药作为震源。因而,造成在这些地区施工时,没有符合环保要求的勘探激发源可用。本文首先介绍了泥枪的结构和工作原理,对泥枪沉放装备技术进行了探讨,同时对供气系统进行了匹配计算;并对样机进行了可行性试验,试验证明此技术可满足滩浅海过渡带等地区的非炸药施工要求。

With the enhancement of the environmental protection in oil exploration, vibroseis and air gun can＇t be used in transition zone. There is no appropriate source in those zones because explosive energy source is not al- lowed. The paper introduces the structure and operational principle of mud gun, and calculates the gas supply sys- tem, then conducts feasibility test. It is proved that the new technology could satisfy the exploration in transition zone.
