砾岩油藏孔隙度低、储集层物性差,开发和稳产难度大,是一个世界级油气开采难题。2009年,新疆油田砾岩油藏二次开发深部调驱技术与应用被确定为中石油重大试验项目,并在克拉玛依油田六中区、七区的克下组砾岩油藏进行整体深部调驱技术攻关试验。试验分为2期,2010年初开始施工。克下组砾岩油藏是新疆油田二次开发的主体,含油面积312.9 km2.2012年4月,一期试验顺利完成。由于新疆油田砾岩油藏类型多、储集层复杂,一、两个区块的现场试验尚不能涵盖所有油藏类型。一些技术问题,诸如砾岩油藏深部调驱机理,深部调
Conglomerate reservoirs have low porosity and poor reservoir physical properties, making it difficult and difficult to develop and stabilize. It is a world-class oil and gas exploration problem. In 2009, the deep flooding control technology and application of secondary development of conglomerate reservoir in Xinjiang Oilfield was determined as a major pilot project of PetroChina. The deep submerged flood control technology was carried out in the Cretaceous reservoir of Kexia Formation in the six middle and seven districts of Karamay Oilfield Research test. The test is divided into two phases, beginning construction in early 2010. The lower Cretaceous conglomerate reservoir is the main secondary development of Xinjiang Oilfield, with an oil-bearing area of 312.9 km 2. In April 2012, the first-stage test was successfully completed. Due to the large number of conglomerate reservoirs and the complicated reservoirs in Xinjiang Oilfield, all the reservoir types can not be covered by field tests in one or two blocks. Some technical issues, such as the mechanism of deep flooding of conglomerate reservoirs, deep adjustment
