黄骅凹陷孔南地区已经历经40多年的勘探开发,进入持续递减开发阶段,新增资源品位逐渐变差,油田储采比逐年降低,后备资源不足,原油生产形势严峻,所管辖的枣园、王官屯等7个油田,其中低动用储量3862万吨,未动用储量7763万吨。而这些低品质的低动用和未动用储量具有油藏埋藏深、储层物性差、构造复杂、岩性变化大、单井产能低等特点或难点。如何有效提高动用率,实现经济有效开发,完成新区产能建设,实现原油稳产和上产,需要开展深入的研究,形成配套开发技术对策。
Kongnan area of Huanghua Depression has gone through more than 40 years of exploration and development and has entered a phase of continuous decline and development. The grade of new resources gradually becomes worse. The ratio of oil and gas reserves to production and mining has been decreasing year by year. The reserve resources are insufficient and the crude oil production situation is grim. Zaoyuan and Wangguantun And other seven oil fields, of which 38.62 million tons of low-use reserves, unused reserves of 77.63 million tons. However, these low-quality low-utilization and non-utilization reserves have the characteristics or difficulties of deep buried oil reservoirs, poor reservoir physical properties, complicated structures, large changes in lithology and low single well productivity. How to effectively improve the utilization rate, achieve economic and effective development, complete capacity building in the new district, and achieve stable production and production of crude oil requires in-depth research and development of technical measures for supporting development.
