摘　　要：针对文东非均质多油层油田开发中存在的突出问题及采油工艺现状，在国内首次正式提出了一套井网、多套层系、强注强采、高速开采的逐层段上返开发的新思路，丰富了细分层系的概念，并选择试验区开展先导试验。试验取得了成功，其成果直接应用于文东油田的开发调整，获得较好的开发效果。该方法从根本上解决了非均质多油层油田层间矛盾突出、剖面动用状况差、储量水驱动用程度低等问题，实现了用较少的钻井达到细分层系、加密井网、高速开采、提高采收率的目的。In order to solve the problems existing in the development of Wendong heterogeneous stratified Oilfield, a new thought of upward bed-by-bed waterflood development with a set of well patterns for forced injection and high-speed production in stratified reservoir has first been presented by us in China,which enriched the concept of subdividing a series of strata. An experimental area was chosen for the pilot test. In consequence, the successful experimental result has been directly applied to the development adjustment in Wendong Oil- field,and a good profit is gained. The test puts an end to the problems of the conspicuous contradictories among layers,lowly-producing profile and low recoverable reserves of water-drive in heterogeneous stratified reservoir,the goals of subdividing a series of strata,infill drilling,high-rate development and EOR with few wells are achieced.
