锦626块目前存在的主要问题是整个区块水淹严重，且水淹具有见水较早、水淹速度快、见水量大、水淹情况复杂等特点。通过对水侵规律进行研究，该区块的水侵在纵向上及平面上具有生产井段内高渗层、下部层相对水侵较严重、边底水沿压降梯度大的方向呈指形或线形侵入等特征。引进先进的监测手段和技术，获取了产液剖面监测资料，从而对水淹区边底水水侵状况及剩余油分布规律等有了较为清晰的认识，与堵水、补层等措施紧密配伍，应用于锦626块东部整个水淹区，不断挖潜层间剩余油，提高了储层的动用程度。

At present, Block Jin 626 is seriously flooded with water, which is the main problem of the whole block. Early water
breakthrough and fast and complex watered out are the current situations of this block. Through the study, we have found that the
block flooding has some characteristics that it is deeply penetrated and seriously flooded in the lower layer which is being produced.
The water invasion along the direction of larger pressure gradient is in finger or linear shape. Advanced monitoring technologies are
introduced and liquid-producing profile data are acquired. At the same time, we have got a more clear understanding of the
remaining oil area by using advanced monitoring tools and technologies and matching with other measures like water plugging and
layer adding. In the entire eastern zone of the block, these technologies are used to enhance the reservoir producing extent
