小砂体薄油层开发方式优化研究

随着勘探开发的不断深入,胜利油田可供开发的优质储量越来越少,挖潜难度也越来越大,因此,工作重心已逐渐向小油砂体和薄油层等非主力油层方向转移,如何合理的开发小油砂体和薄油层,就成为当务之急.针对孤东油田七区西301个小油砂体的石油地质储量,运用油藏工程与数值模拟相结合的方法,对不同类型的小油砂体和薄油层的合理开发方式进行了综合优化研究,确定出了不同类型小油砂体经济可行的开发方式,这对今后提高类似老油田的采收率和可采储量具有重要的指导意义.

OPTIMAL RESEARCH OF DEVELOPMENT SCHEME FOR SMALL OIL SAND BODIES AND THIN OIL FORMATION

Along with ceaselessly deeper of exploration and development, high quality reserves are less and less. At present, the target had gradually been diverted to small oil sand body and thin oil formation, and more and more difficult to develop. Under this kind of development status, and how to reasonable develop small oil sand body and thin oil formation, and it is a key problem. This article contraposed number 301 small oil sand bodies and geological reserves of Qiquxi Block in Gudong Oil-field, and applying the methods of petroleum engineering combining numerical simulation, the reasonable development scheme of small oil sand body and thin oil formation is optimized researched and the economic and feasible development scheme for different small oil sand body and thin oil formations are determined. It is significant to enhance recovery factor and recoverable reserves of old oilfield.
