Research On The Condition Of Hydrocarbon Accumulation And Evaluation Of Project In Gaosheng Buried Hill

The condition of hydrocarbon accumulation consist of mother rock, trap, reservoir, caprock, migration and preservation.It is the first condition of hydrocarbon accumulation.Wheneach condition develop a good deploy in times and space,it can form hydrocarbonaccumulation.The condition of hydrocarbon accumulation can control the formation of bigreservoir.Gaosheng buried hill is the important target area in Xibu depression.with the depth studyof exploration activity, petroleum geological workers recognize that the condition ofhydrocarbon accumulation play important affect in Gaosheng buried hill. This paper analyzesthe condition of hydrocarbon accumulation in depth study and recognize that Gaoshengburied hill has good condition of hydrocarbon accumulation.The mother rock of Shasan andShasi in Taian sag and Chenjia sag offer material bastion for hydrocarbonaccumulation.Tectonic movement form some style of trap.Ganite of Archean Erathem andaposandstone and carbonate of Proterozoic offer the good reservoir. The heavy overlyingbasalt is the good capping formation.on the base of the study,the paper conclude the modelsand control factor of Gaosheng buried hill.It recognized that Gaosheng buried hill has themodels of two-way oil servicing and mother rock, trap and reservoir is the control factor ofhydrocarbon accumulation.The end,the paper evaluate the favor project in Gaosheng buriedhill.It systematically studied the tectonic format and find favor trap area62km2, forecastresource amount8668×104t.It proposed ten proposition of geometric arrangement of wellsand deployed six exploration wells.It opened the new phase of buried hill prospect in thenorth of Xibu depression.
