Research status of hydraulic fracturing fracture propagation in conglomerate
With the proportion of conglomerate oil and gas reservoirs in newly proved re-serves increasing year by year,its development value is becoming more and more prominent.However,due to the unique geological characteristics,complex pore structure,strong hetero-geneity and weak conductivity of conglomerate oil and gas reservoir,the effective utilization of its reserves faces many challenges.Among many stimulation technologies,hydraulic frac-turing is one of the better choices to solve such problems.However,due to the existence of gravel,the propagation of hydraulic fracturing fracture network becomes extremely complicat-ed,the construction difficulty is greatly increased,and the stimulation effect is not ideal.The purpose of this paper is to summarize the research status of hydraulic fracturing fracture propagation in conglomerate,clarify the law and influencing factors of hydraulic fracturing fracture propagation in conglomerate,and expect to provide certain reference significance for the development of conglomerate oil and gas reservoirs through research and discussion.
