对安塞油田杏河地区长X储层的地质特征进行了论述,该油藏是受砂体展布和鼻状隆起双重控制下形成的岩性—构造油藏。该地区长X储层总体来说物性相对较好,地层压力低。针对储层的特点,进行了长X层压裂技术研究,提出了适合该区长X储层的压裂改造技术,并在近两年的应用中取得了良好的效果。 The geological characteristics of the Chang X reservoir in the Xinghe area of ​​Ansai Oilfield are discussed. The reservoir is a lithologic-structural reservoir formed under the dual control of sand body distribution and nose uplift. As a whole, the long X reservoirs in the area have relatively good physical properties and low formation pressure. According to the characteristics of reservoirs, the research on the fracturing technology of long X-layer was carried out. The fracturing technology suitable for the long X reservoir was proposed, and good results were achieved in the past two years.
