随着东濮凹陷勘探开发程度的不断加深,中原油田已进入高成熟勘探阶段,勘探对象逐渐转为勘探程度相对较低的深层低渗透油气藏和复杂断块油气藏。针对此类油藏复杂的地质条件,按一般的勘探开发程序,必然导致建设周期长,勘探开发效益差。面对新的勘探开发形势,如何提高勘探开发效益,坚持滚动勘探开发一体化及滚动勘探新技术、新方法的应用,是实现油田少投入、多产出、早收益的有效途径。本文通过近几年来东濮凹陷滚动勘探开发的实践,概述了多层系、低渗透、复杂断块油气藏滚动勘探开发的新思路及取得的主要成果,形成并建立了一套适合东濮凹陷地质特点的滚动勘探开发技术序列,对高成熟地区的增储稳产具有较好的借鉴意义。

At present , the exploration of Zhongyuan area has come into a mature stage and the exploration target has been gradually turned to the deep layered and low permeable reservoir Since this kind of reservoir have complicated geological structures , the conventional exploration and development program will cause longer construction period and Poor exploration and development efficiency Facing this new exploration and development situation , the most effective way of realizing“less input , more output and early benefit”is found to enhance exploration and development efficiency , to adhere to systematic progressive exploration and development , and stick to application of systematic progressive exploration and development and to the application of new technology and methods This paper brieflyexplain & new technologies and methods through practice of several years progressive exploration , and get the new ideas of progressive exploration in multilayered , low permeable reservoir and the synthetic evaluation technology in Dongpu Depession The paper can also provide some references for adding more reserves and stabilizing production in the area with mature exploration degree.
