摘要
By use of seismic data interpretation and drilling data,it conducts the required minimum late activity intensity of fault in hydrocarbon accumulation and preservation in Shaer member of western depression of Liaohe Qijia-Yuanyanggou area,the results show that there are four faults with the same strike in Shaer member,in the period Guantao Group to Quaternary after the end of Dongying to Guantao deposition,activity intensity of f1 fault is maximum,followed by f3 fault,again is f4,the activity intensity of f2 fault is weakest.There is a close relationship between oil and gas distribution and late activity intensity of fault,the smaller parts of strength of post-event of fault,the more enriched oil and gas,and drilling success rate is higher;the other hand the more low.
