胜利海上油田大部分油井经过长期的高强度笼统合采,层间干扰现象越发突出,开采过程中对地层生产情况监测不清、难于及时的做出调整,为了解决上述问题,研究了海上油井防砂后的分采分测管柱。该管柱可以实现分层采油分层测试,针对出砂油藏可以利用砾石充填进行两个油层的大通径分层防砂,利用小直径可控开关实现分层开采。该管柱的测试部分采用了先进的光纤传感技术,随时监控井下生产动态,初步达到智能完井的目的。
In order to solve the above problems, the research on the effect of sand control of offshore oil well is carried out. The results show that, Subsection points after the test tube. The pipe string can realize stratified oil production stratification test. For sand production reservoir, gravel packing can be used for large-diameter sand control of two oil layers and stratified mining using small diameter controllable switches. The test section of the column using advanced optical fiber sensing technology, ready to monitor downhole production dynamics, the initial completion of intelligent completion of the purpose.
