摘要
台105地区动态和静态特征研究表明,油田受天然微裂缝、砂体沉积微相类型、微构造等地质因素制约,注采矛盾突出,开发效果较差。综合研究指出:及时发现天然微裂缝是确定合理注采井网的关键;砂体沉积微相差异导致油层层间、平面矛盾加剧,注水在纵向以及平面上不均衡;微构造是油田注采不受效的主要因素。
Dynamic and static characteristics show that Tai 105 oilfield is restricted by natural microfracture, sedimentary microfacies of sands and microteclonics, presenting injection - production problem and poor development effect. It has been pointed out through comprehensive study that to discover natural microfracture in time is critical for determining rational flood pattern; the differences in sedimentary microfacies of sands has resulted in sharpening of interlayer and areal problems and disproportionate vertical and areal injection; and micro-tectonics are major factors of ineffective water flooding.
