Mid-Saertu Gaotaizi Oil Reservoir In Well Pattern Optimization Adjustment Method Research

Mid-Saertu Gaotaizi oil reservoir in high platform reservoir put into development in1982, so far, comprehensive water cut of 94.6%, has entered for determining the development phase. With the deepening of the oil field development and residual oil distribution is complex, rising, interlayer contradiction between Wells, based on drilling Wells in the development of long and large injection-production well spacing, etc., which resulted in the large difference of the use of the reservoir, and low level of production problems, according to the actual circumstance of reservoir, Mid-Saertu Gaotaizi oil reservoir well pattern adjustment method is studied and formed a high platform overall adjustment model, reservoir formation pattern, for the future Mid-Saertu Gaotaizi oil reservoir formation in well pattern adjustment provides the technical support.This paper analyzes Mid-Saertu Gaotaizi oil reservoir at present problems in using condition and remaining oil distribution, to determine Mid-Saertu Gaotaizi oil reservoir well pattern adjustment is required. And through the analysis of the main control factors of interlayer interference, and to establish a conceptual model, the numerical simulation research,it is concluded that formation during restructuring combined permeability reservoir permeability differential, injection-production well spacing and technical limit, formed Mid-Saertu Gaotaizi oil reservoir formation pattern overall adjustment model, and two parts of Mid-Saertu Gaotaizi oil reservoir formation well pattern adjustment scheme design,Increase the total recoverable reserves 173.0×104t, realized the solve the contradiction in the development, the biggest potential in residual oil, enhanced oil recovery.
