生产动态测井资料在J油田开发中的应用

Application of Production Dynamic Logging Data in J Oilfield Development

J油田已开发50年,大部分区块都已进入到注水阶段,均存在综合含水上升、产油量下降的问题。为了了解油层的动用情况以及油、水分布状况,弄清高含水层、低产液层以及未动用层的确切位置,利用生产动态测井所提供的注水剖面和产液剖面等资料,掌握注水井中每个层位的绝对注入量、相对注入量和生产井中每个油层的油、气、水产量,对油层污染进行判断,验证封堵及堵水情况,为油田增产提供有利的理论依据。

J Oilfield has been developed for 50 years and the most of blocks have entered into the water injection stage,where existed the problems of comprehensive water content increase and the production decline.In order to understand reservoir producing and the distribution of oil and water,clarify the exact positions of high water content and low liquid producing layers and the non-producing layers,the data of injection profile and liquid producing profile obtained from production dynamic logging are used to provide absolute and relative injection volumes of each layer,oil,gas and water production of each reservoir is used to judge the formation damage to check the sealing and water blocking,it provides a theoretical basis for enhancing oil production of the oilfield.
