摘要：

南堡油田M区是冀东油田的主力注水开发区块,目前已进入中含水阶段,主体区域注水效果显著,局部区域受井间砂体连通性认识不清的影响,注水效果不明显,水驱储量动用程度较低。准确判定井间的砂体连通性,对于完善该区注采井网,提高采收率意义重大。该区砂体横向变化快,纵向砂体层数多而薄,叠置关系复杂,井间砂体连通认识难度大。针对这个问题,通过地质、地震、测井、油藏等多学科综合技术来判定井间砂体连通性,其中包括地震相技术、地震属性技术、地震反演技术、油藏动态分析技术等。井震藏结合的技术手段,已广泛应用于该区的井间砂体连通性判定,并在开发实践中取得了良好效果。研究成果提高了该区井间砂体连通性判定的准确率,为指导该区的油藏开发调整提供了有利依据,对同类型油藏的井间砂体连通性判定具有较好的借鉴意义。

Abstract:

M area in Nanpu Oilfield is the main water injection development block of Jidong Oilfield, and it has entered the middle water cut stage at present. The water injection effect in the main area is remarkable, but in some areas, the effect is not obvious due to the unclear understanding of inter-well sand body connectivity, and the utilization degree of water injection reserves is low. An accurate evaluation of inter-well sand body connectivity is of great significance for improving injection and production well pattern and enhancing oil recovery in this area. The sand bodies in this area change rapidly in transverse direction, and the number of layers in longitudinal direction is large and small, thus it is difficult to recognize the inter-well sand body connectivity. In order to solve this problem, the inter-well sand body connectivity is evalued by the multi-disciplinary comprehensive technology including including seismic phase technology, seismic attribute technology, seismic inversion technology and reservoir performance analysis technology. With the combination of well, seismic and reservoir, this technology has been widely used to determine the inter-well sand body connectivity in this area, and achieved good results in development practice. The research improves the accuracy of inter-well sand body connectivity evaluation, and provides a favorable basis for guiding reservoir development adjustment in this area. It is of good reference for the evaluation of the inter-well sand body connectivity in the same type reservoir.

Key words: Nanpu Oilfield, inter-well sand body connectivity, combination of well,seismic and reservoir, seismic phase technology, seismic attribute technology, seismic inversion technology, reservoir performance analysis technology
