构造+岩性油气藏地震处理、解释一体化实例研究
Keywords: 相对保持提高分辨率处理,储层构造等时格架解释,储层沉积演化解释,砂体构型解释,地质构造成图
Abstract:
？构造+岩性油气藏正逐步成为油气藏勘探重要目标之一,构造+岩性油气藏的主要特点是构造简单,储层岩性复杂。构造+岩性油气藏勘探的主要难点是如何提高储层构造解释精度和储层沉积解释精度以及相应的速度求取精度和地震分辨能力。针对以上问题,基于珠江口盆地番禺油田开展了构造+岩性油气藏的地震勘探方法研究。研究区存在海底和第四系厚度变化较大、长波长空间变速、气云、地震分辨率、构造精度和储层沉积解释精度等问题。多次波压制、相对保持提高分辨率、高精度地震速度求取、储层构造等时格架解释、储层沉积演化与砂体构型解释,以及井震地质构造成图等是解决构造+岩性油气藏勘探问题的关键技术。后期开发井验证表明,对于研究区埋深约3000m的储层,通过以上精细处理和解释一体化系列技术,其构造+岩性的储层地震勘探精度可以达到千分之一的精度范围。
