我国属于石油地质条件十分复杂的国家,低品位石油资源占有举足轻重的地位。应用水平井针对性解决层间矛盾能够有效解决低品位薄层油藏的开发难题,本文以W83块为例,对出砂严重的薄层稠油油藏,在准确识别油层的基础上,开展油藏工程设计,确定了水平井部署参数及原则,共部署水平井14口,采用精密防砂筛管完井有效解决了出砂难题,实施7口井均取得理想效果。
China belongs to a country with very complicated petroleum geological conditions, and low-grade oil resources occupy a pivotal position. The application of horizontal well-targeted solution to the problem of interlayer conflict can effectively solve the development problem of low-grade thin-layer reservoirs. Taking W83 block as an example, on the basis of accurate identification of the oil layer, The reservoir engineering design has determined the deployment parameters and principles of horizontal wells. A total of 14 horizontal wells have been deployed. The completion of well-controlled sand control screens effectively solved the sand production problems and achieved satisfactory results in 7 wells.
