辽河Ng油藏SAGD生产过程中储层变化及影响
摘要
Abstract
A large amount of high temperature steam is continuously injected into the reservoir during SAGD production and strong physical and chemical reactions will inevitably take place among the solid, liquid and gas phase substances in the formations, especially the water - rock interaction will cause the partial character and pore structure of reservoir rocks to change. Through analysis of the core data from the coring wells in the test area, it is considered that such changes as dissolution and transformation of rock minerals , swelling of clay minerals and migration and blockage of particles have taken place in the Ng reservoir during SAGD production , leading to the change of and damage to reservoir physical property and pore structure. The key factors and mechanism of reservoir damage were analyzed and some recommendations were given to eliminate the damage, which has provided a basis for adjusting the SAGD performance.关键词
