Laboratory Research On The Diversity Of Horizontal Well Thermal Fluid Drive

Multiple thermal fluid drive is an efficient heavy oil technology, in recent years, due tothe viscous oil development technology, conventional tight crude oil supplies and the impactof high oil prices, among other factors, heavy oil gradually reveal its status as a replacementfor regular oil and energy strategies. Major fields in efforts to increase heavy oil recovery.Current domestic oil thermal recovery of heavy oil has been largely is, methods include steamswallow, steam flooding and the situ. Exploitation on steam drive in usually experiences bothin the process. The one hand, steam flooding many times in front of steam Huff and formationpressure decrease more quickly, and steam alone may not be permanently maintained andadditional formation pressure on the other, due to the steam and the flow of crude oil capacityvaries widely, rush at the steam drive process occurs in a single layer, single well gaschanneling phenomena such as, steam overlap, resulting in significant reduction in thermalefficiency of steam flooding. Multi heat flow body drive technology in both at home andabroad of test research also comparison less, is a started stage, this article based on steamdrive theory of based Shang, used test of method, through application level well a dimensionacting model test equipment, optimization has different of injected temperature, and differentof injected volume, and different of drive on behalf of way on multi heat flow body drive ofeffect, uses three dimensional real die test equipment research has injected multi heat flowbody Hou temperature field of exhibition cloth, and development effect and productiondynamic.35-2nanpu oilfield mining provides a feasible basis.
