本文主要叙述马20断块注水开发进入到中后期阶段调整开发层系的实例。随着油田开发的进展,油井在多层合采条件下,层间干扰严重,含水量上升快,产油量迅速递减。为了确保油田稳产,对原来一套层系合采,细分为三套开发层系。在开发调整中应用多方面资料,在搞清油层油水分布情况的基础上部署调整井,并对每口井进行水淹层测井,掌握各个油层的水淹状况,然后整体地对注采井别进行调整和确定新油水井射孔井段。调整后取得了较好的效果。
This article describes the Martin 20 fault block water injection into the middle and late stages of adjustment of the development strata examples. With the progress of oilfield development, under the condition of multi-layer and combined production, the inter-layer interference is serious, the water content increases rapidly and the oil production decreases rapidly. In order to ensure stable oil production, a set of layers of the original mining system, subdivided into three sets of development strata. In the development and adjustment of the application of a wide range of information on the basis of the oil and water distribution to find out the deployment of adjustment wells, and each well waterlogging logging, grasping each reservoir flooding conditions, and then the overall injection well Do not adjust and determine the new oil well perforated section. After adjustment has achieved good results.
